FAQs on Database Management System(DBMS)

Q.1 what is database.

A database is a collection of organized data which can easily be created, updated, accessed, and managed. Records are kept maintained in tables or objects. A tuple (row) represents a single entry in a table. DBMS manipulates data from the database in the form of queries given by the user.

Q.2 What are different languages present in DBMS?

DDL (Data Definition Language) : These are the collection of commands which are required to define the database. E.g., CREATE, ALTER, RENAME, TRUNCATE, DROP, etc. DML (Data Manipulation Language) : These are the collection of commands which are required to manipulate the data stored in a database. E.g., SELECT, UPDATE, INSERT, DELETE, etc. DCL (Data Control Language) : These are the collection of commands which are dealt with the user permissions and controls of the database system. E.g, GRANT, and REVOKE. TCL (Transaction Control Language) : These are the collection of commands which are required to deal with the transaction of the database. E.g., COMMIT, ROLLBACK, and SAVEPOINT.

Q.3 What are the ACID properties in DBMS?

The full form of ACID is Atomicity, Consistency, Isolation, and Durability these are the properties of DBMS that ensure a safe and secure way of sharing data among multiple users. A – Atomic: All changes to the data must be performed successfully or not at all. C – Consistent: Data must be in a consistent state before and after the transaction. I – Isolated: No other process can change the data while the transaction is going on. D – Durable: The changes made by a transaction must persist.

Q.4 What are the Advantages of DBMS?

The followings are the few advantages of DBMS : Data Sharing: Data from the same database can be shared by multiple users at the same time. Integrity: It allows the data stored in an organized and refined manner. Data Independence: It allows changing the data structure without changing the composition of executing programs. Data Security: DBMS comes with the tools to make the storage and transfer of databases secure and reliable. Authentication and encryption are the tools used in DBMS for data security.

What is DBMS?

DBMS stands for “Database Management System.” It’s a software system designed to manage, store, organize, and retrieve data from a database. A database is a structured collection of data organized and stored to allow for efficient querying, manipulation, and analysis.

A DBMS provides an interface and tools for users and applications to interact with the database without worrying about the underlying complexities of data storage and retrieval. It offers various features and functions that facilitate data management.

Common examples of DBMSs include MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, SQLite, and MongoDB. Each DBMS has its strengths, features, and use cases. The choice of a specific DBMS depends on factors such as the nature of the data, scalability requirements, performance considerations, and application needs.

What are the Types of DBMS?

Several types of Database Management Systems (DBMS) are designed to cater to specific data management needs and scenarios. Here are some of the main types of DBMS:

Relational DBMS (RDBMS)

This is one of the most common types of DBMS. It organizes data into tables with rows (records) and columns (fields) and establishes relationships between tables using keys. SQL is typically used to query and manipulate data. Examples include MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, and SQLite.

Object-Oriented DBMS (OODBMS)

These systems are designed to handle complex data structures, including objects with attributes and methods. They are useful for applications that deal with object-oriented programming languages. Examples include ObjectStore and ObjectDB.

Document DBMS

Also known as document stores or NoSQL databases also store and retrieve data in flexible, schema-less document formats like JSON or XML. They are well-suited for storing and managing semi-structured or unstructured data. Examples include MongoDB, Couchbase, and CouchDB.

Key-Value Stores

These databases store data as key-value pairs, where each value is associated with a unique key. They are efficient for simple read-and-write operations, making them suitable for caching and high-throughput scenarios. Examples include Redis, Amazon DynamoDB, and Riak.

Columnar DBMS

These systems store data in columns rather than rows, which can provide significant performance benefits for certain analytical workloads. They are optimized for data warehousing and business intelligence applications. Examples include Apache Cassandra and Google Big Table.

Graph databases store data in nodes and edges, representing entities and relationships between them. They are designed for managing and querying highly interconnected data, such as social networks or recommendation systems. Examples include Neo4j and Amazon Neptune.

Time Series DBMS

These databases are designed to handle time-stamped data, such as sensor data, logs, and financial market data. They provide efficient storage and querying mechanisms for time-series data patterns. Examples include InfluxDB and OpenTSDB.

NewSQL Databases

These are a new generation of relational databases whose main aim is  to combine the advantages of traditional databases via scalability and performance capabilities. For examples CockroachDB and NuoDB.

Spatial DBMS

These systems, such as geographic information systems (GIS), are specialized for storing and querying spatial data. They enable efficient manipulation and analysis of location-based information. Examples include PostGIS and Oracle Spatial.

In-Memory DBMS

These dbms projects store data completely in memory by offering high-speed data retrieval and processing. They are often used for real-time analytics and applications that require rapid data access. Examples include SAP HANA and VoltDB.

DBMS Project Ideas

The following are some easy and exciting dbms project ideas. Choose one according to your requirements:

1. E-commerce Platform

You must’ve seen multiple online retail platforms. Some great examples of such platforms are Amazon and Flipkart. In this DBMS project, you’ll have to develop a similar e-commerce platform, where a customer can register and buy a product.

You can also consider doing our  Java Bootcamp course  from upGrad to upskill your career.

Your developed platform should have a registration window where the user will provide their name, bank name, and bank account number. This information will enable them to make transactions easily. After they’ve registered, the system should give them unique user IDs and customer IDs. They should have the option to set up their passwords. 

Any e-commerce platform would be incomplete without having any products to sell, wouldn’t it? So it should have product listings as well, classified according to their prices (or some other criterion). The user should have the option to buy one or more products from your platform. And after the user makes a purchase, the system would generate an invoice, which will contain the user’s name. The system can allow ordering from different suppliers according to availability. 

Featured Program for you:   Fullstack Development Bootcamp Course

Using DBMS for an e-commerce platform will give you extensive experience in this technology. It’ll help you understand how online platforms use and interact with databases. Still, this project will undoubtedly take some time and effort. 

This project makes for one of the most relatable database projects , as e-commerce uses databases for tracking the transactions, and products database, the marketing team also uses the DBMS to track the traffic, acquire potential customers and retain the existing customers. The e-commerce industry is running on having a strong database because it is online and data is the new oil. Also, just having data is not enough, having the strong ecosystem of having a string core database is what makes it all efficient.

2. Inventory Management

Every organization has an inventory to manage, which takes up a lot of resources. Usually, an organization would assign the duty of inventory management to two or more people who’ll keep an eye on it and ensure that all the supplies are available. If any item is missing, the manager would order the same. This system works effectively if the organization is tiny, but that’s not always the case.

You can solve this problem of businesses and build an inventory management system. The goals of your design would be the following:

• Increase the inventory turnover
• Optimize the inventory and the stock levels
• Reduce the number of safe stock levels
• Get low material prices.
• Make it easy to understand and access.
• Reduce the operational costs of the inventory (storage cost, insurance cost, etc.)
• Classify the objects in the inventory according to their stock levels

As you can see, an inventory management system will allow its client to save a lot of time and resources. They can find the stock levels in their inventory and plan accordingly. It will make the enterprise more efficient and productive. 

This is one of the beginner-level database projects on this list. You can work on it even if you don’t have much experience with developing database solutions. 

This is one of the good database project ideas , as inventory is the core of any business. Especially after the pandemic hit, most businesses have turned online. Not only the recently turned online businesses but the recent and old businesses were well. If an organisation has a solid core management system for inventory tracking, they could not only increase the business but also can understand the leakages.

The following can be the sub-topics-

• What is inventory management?
• Why inventory management?
• How DBMS is useful for inventory management?
• What are the methods?
• Micro, Medium, and Macro level businesses that use DBMS for inventory.

3. Railway System

The railway network of our country is one of the most complex public establishments. You can design a database solution for this network and make the management of the same more natural. Your system should have the following pieces of information:

• Station names
• Tracks that connect those stations (to keep things simple, you can assume that only one track runs between two stations)
• Train IDs with names
• Schedules of the trains 

The train schedules should have information on the stations from where the train starts and by when it reaches the destination. It should also include information on which stations it passes through during its journey. 

To keep things simple, you can assume that every train completes its journey within a day, and they run daily. However, you’ll also need to store information on the sequence of the stations a train passes through. For example, if a train starts from Delhi and goes to Kolkata through Lucknow, then you’ll need to add the arrival and departure times of the train for all these stations. Keeping the stations in sequence will allow easy management of trains and their data.

Also visit upGrad’s Degree Counselling page for all undergraduate and postgraduate programs.

Till here, the project is rather easy. You can make it more challenging by adding the passenger information of every train such as its coaches, seat numbers, types of coaches, passenger names, and so on. This project might take some time to complete, but it’ll help you showcase your knowledge of database management solutions while solving a significant issue of a public authority.

India has a very big network of railways, not only that but the metros also have become a very significant part of commutation over the country. Both these types of railways have a wide network and people’s daily commutes depend upon them. Keeping a track of the train’s arrival, departure, first time of arrival at a particular station and last train departure also have a big role to play as people plan their schedules accordingly. Keeping a track of these is really important. Not only that but also keeping the tracks safe from collisions and any haphazard also is important for the smooth operation of the network. This brings another factor which is revenue, the need for revenue generation arises because of the large number of users. Keeping a track of tickets, and distance travelled is necessary in order to track the overall revenue which eventually helps in the country’s GDP. This is why is one of the important topics for the database project topics .

The sub-topics could include the following-

• What are the types of railway networks?
• How DBMS could be used in the railway industry?
• Advantages of using DBMS in the railway industry.
• Disadvantages of not using the DBMS in the railway industry.

4. college data management.

Colleges have multiple departments where every department offers many courses. These departments have a head (HOD) and various instructors. Even though there are many instructors, one instructor can only work in one department. As you can see the organization structure of a college is quite complicated and requires a lot of effort to manage. 

In this database project, you can build a solution to tackle this problem. It would store all this information about the college and its departments. However, the information we’ve discussed above isn’t sufficient for a college. We need to mention the courses as well.

A course can have only one instructor, but an instructor can have multiple classes. You’d need to add this information to the database system as well. You can make this project more advanced by adding the course enrollment information. 

You can add the enrollment information of the students as to how many students have taken a particular course. 

The system should allow easy access. Your developed DBMS-based solution would allow a college to save a lot of time and resources; moreover, the user could see all the college information from one place and modify it accordingly. 

Along with that, colleges or universities hold a lot of sensitive information about their students’ such as-

• Personal information
• Bank Details
• Parent’s information, etc.

These kinds of personal information need to be secured from online theft and unauthorised access. The security of this information is the responsibility of the college and universities. And this is why the university management system is one of the important topics for database projects.

The sub-topics could include-

• What is university database management?
• Why is university database management important?
• Advantages and disadvantages of DBMS for university database management.

5. library data management.

If you’re an avid reader, then chances are, you must’ve gone to a library. And you may already know how many books a library has to keep track of. Libraries don’t have a lot of staff, but they have to keep a record of all the books they have and the books they have lent. You can simplify the management of a library’s data. 

You should start with students and faculties, i.e., people can get books from the library. Now, there would be a significant difference between the number of books a student can get and the number of books a faculty can get. So, add those limits in your system as well. Then, every book would have a unique ID.

Books with the same title and author would have different IDs according to their copies. You’ll have to add entries for every book. And then, add the details of who issued the book and when with the duration of their ownership. Your DBMS-based solution should also have details on the books that people haven’t returned and the due fines. 

Along with keeping the labeling organised for the books, it is equally necessary to modify the data and keep constant track of the books which keeps getting published and returned. Also keeping the track of the worn-out books, restock, newly added books, etc. Along with that, libraries also maintain the data genrewise. All of these constitute the library database management system that helps the libraries run their operations on autopilot and also helps the librarians.

6. Solution for Saving Student Records

You can build a solution that saves student records for an educational institution. Handling student records is no easy feat. You need to keep their name, subjects, fees, any provision of concession, and their academic progress. A DBMS-based solution will allow the client to save a lot of time and effort.

Your design goal should be to have separate files for each student where the data will store information about the student. You can start by adding the following sections:

• Student’s Name
• Subjects (or Stream)
• Grades (or Marks)
• Concessions (or Scholarship)
• Additional Information

It’s one of the easy database project ideas. You can take it a step further, and add the option to include students of different grades or sections. Your designed system should allow the admin to enter the details mentioned above. And the admin should be able to access it easily. 

7. Hospital Data Management

Hospitals have unique data requirements. Not only do they have to maintain the medical records of their patients, but they also have to manage their staff and its multiple departments. You can solve the data-related problems of hospitals by creating a DBMS solution. 

First, you should assign unique IDs to the patients and store the relevant information under the same. You’ll have to add the patient’s name, personal details, contact number, disease name, and the treatment the patient is going through. You’ll also have to mention under which hospital department the patient is (such as cardiac, gastro, etc.).

After that, you should add information about the hospital’s doctors. A doctor can treat multiple patients, and he/she would have a unique ID as well. Doctors would also be classified into different departments. 

Patients would get admitted into rooms, so you’ll need to add that information to your database too. Apart from that, there would be distinct rooms (ICUs and Operation Theaters) in the hospital. Then, you’d have to add the information of ward boys and nurses working in the hospital and assigned to different rooms. 

You can start with a small hospital and expand it as you move on. Make sure that the data is easily understandable and accessible. 

Also, the hospitals have a lot of information with them such as the patient’s history, pharmacy, test results, number of beds, information about the helping staff, etc. All of this data needs to be managed as they are crucial to the hospital’s operations and helps in its smooth functioning. This database management helps in routine or emergency visits as well.

• What are the advantages of DBMS in the healthcare industry?
• What are the disadvantages of not using DBMS in the healthcare industry?

8. Blood Donation Management

Another DBMS project idea is to create a blood donation clinic. You should start by adding donor names and assigning them unique IDs. Add their details and relevant information such as blood type, medical report, and contact number. Similarly, add patient names with unique IDs, details on their medical conditions, and blood types. 

After you’ve created a database of patients and donors, you can work on a database for the blood bank. There, you’ll have to add the name of the blood bank, its staff details, operating hours, and address. 

DBMS is helpful in the blood donation industry by keeping the track of the acceptors and donations. This helps the hospital in keeping a record of the blood donors as well in case of any emergency. And also to help them keep track of the storage.

9. Payroll Management Solution

Managing payroll is one of the most crucial aspects of an organization. So you can create a database solution for this purpose as well. Here, you’ll first have to assign a unique ID to every employee. And then, you’ll need to add the details of the same employee, such as their name, role, department, etc. You’ll have to add information on the unpaid salary of the employee, and the date on which the salary has to be released. Similarly, you’ll have to add the time from which the salary is due. 

After that, the database would need the information on the HRA, DA, medical allowance, and other additions to the basic pay. Similarly, you’ll need to add data on the deductions you need to make (if there are any) such as extra leaves. You can add more difficulty to the project by creating a management solution for a significant organization. In this one, make sure that you add the departmental details of the employee under his/her ID.

Frequently Asked Questions (FAQs)

Database Management System (DBMS) software applications essentially structure and organize data files to provide easy access and standard data assortment. It essentially categorizes the data system so that the user can derive the required information from heaps of data. While Structured Query Language (SQL) isn’t a database management tool, it’s a programming tool that helps access the database. It is linked to the Relational Database Management System (RDBMS), wherein specific user queries are processed to retrieve desired data from the system.

Database Management Systems (DBMS) have made data storage and retrieval much more accessible. Any DBMS needs to have an excellent design for the data to be stored systematically. The DBMS must be designed so that users can access and navigate through the system quickly. A good design ensures uniformity in the data structure to create a reliable DBMS. It should strategize data to avoid duplication of results and increased storage usage. Data design focuses on creating a simple design structure to prevent complexity in locating data and reduce DBMS maintenance.

A file system is essentially categorized as a Database Management System (DBMS) owing to its purpose. However, compared to DBMS, a file system stores data comparatively primordially. Files are taken and stored categorically; however, like DBMS, their relevancy or connection is not mapped out. Hence, retrieval of files gives a limited search result without deep profiling of the particular file. The file system doesn’t manage repeated data files and update data files from different users either. This creates redundancy in the data system and increases storage usage. The file system categorizes data but doesn’t store it in desirable categories.

Data model creation is crucial because it provides a structured representation of data, enabling organizations to understand their data assets better. It helps in organizing, defining, and documenting data requirements, relationships, and constraints, which aids in developing efficient databases and information systems.

Data modeling is the process of creating a conceptual, logical, and physical representation of data to understand its structure, relationships, and constraints. It helps in designing efficient databases and information systems.

Data modeling offers several benefits, including improved data understanding, reduced data redundancy, enhanced data integration, easier database design, and alignment of data with business objectives.

The conceptual data model includes essential components such as entities (representing real-world objects), attributes (characteristics of entities), and relationships (connections between entities). It provides a bird's-eye view of the data without delving into implementation details.

The logical data model offers a detailed representation of data elements and their interrelationships. It abstracts the data from any specific database technology, making it independent of the physical implementation. The advantages include improved data understanding, easier database design, and facilitating seamless data integration.

DBMS Database Management Systems

DBMS • A collection of programs that enables you to store, modify, and extract information from a database. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes. The following are examples of database applications: • Computerized library systems • Automated teller machines • Flight reservation systems • Computerized parts inventory systems

DBMS • One of the most important tools in business and Management Information Systems (MIS) • Changed the way computer applications are developed • Changing the way that companies are managed

DBMS • The database approach begins with the premise that the most important aspect of the computer system is the data that it stores. • The purpose of a database management system is to provide shared access to data, answer questions, and create reports from the data.

Relational Databases • The goal of a relational DBMS is to make it easy to store and retrieve needed data. All data is stored in tables, which consist of columns with rows of data. • Each table has a name and represents objects or relationships in the data. For instance, most businesses will have tables for customers, employees, orders, and inventory.

Relational Databases • Tables • Rows • Columns • Primary keys • Data types • Text • Dates & times • Numbers • Objects Customer Table Phone Name Address City 312-555-1234 Jones 123 Main Chicago 502-555-8876 Smith 456 Oak Glasgow 602-555-9987 Juarez 887 Riviera Phoenix 612-555-4325 Olsen 465 Thor Minneapolis Orders Table Customer Date Salesperson Total_sale 502-555-8876 3/3/04 2223 157.92 602-555-9987 4/4/04 8876 295.53 612-555-4325 4/9/04 8876 132.94 502-555-8876 5/7/04 3345 183.67

DBMS • Requests for information from a database are made in the form of a query, which is a stylized question. For example, the query SELECT ALL WHERE NAME = "SMITH" AND AGE > 35 Requests all records in which the NAME field is SMITH and the AGE field is greater than 35. • The set of rules for constructing queries is known as a query language. • Different DBMSs support different query languages, although there is a semi-standardized query language called SQL(structured query language). • Sophisticated languages for managing database systems are called fourth-generation languages, or 4GLs for short.

QUERY There are three general methods for posing queries: • Choosing parameters from a menu: In this method, the database system presents a list of parameters from which you can choose. This is perhaps the easiest way to pose a query because the menus guide you, but it is also the least flexible. • Query by example (QBE): In this method, the system presents a blank record and lets you specify the fields and values that define the query. • Query language: Many database systems require you to make requests for information in the form of a stylized query that must be written in a special query language. This is the most complex method because it forces you to learn a specialized language, but it is also the most powerful.

QUERY BY EXAMPLE In database management systems, query by example (QBE) refers to a method of forming queries in which the database program displays a blank record with a space for each field. You can then enter conditions for each field that you want to be included in the query. For example, if you wanted to find all records where the AGE field is greater than 65, you would enter >65 in the AGE field. *QBE systems are considered easier to learn than formal query languages.

Access Query Screen (QBE)

Computations • Sum • Avg • Min • Max • Count • StDev • Var SQL SELECT Count(C#), AVG(AccountBalance) FROM Customers ; QBE

RECORD • In database management systems, a record is a complete set of information. • Records are composed of fields, each of which contains one item of information. • A set of records constitutes a file. For example, a personnel file might contain records that have three fields: a name field, an address field, and a phone number field.

FIELD • A space allocated for a particular item of information. • A tax form, for example, contains a number of fields: one for your name, one for your Social Security number, one for your income, and so on. • Fields are the smallest units of information you can access. • In spreadsheets, fields are called cells. Most fields have certain attributes associated with them. • For example, some fields are numeric whereas others are textual, some are long, while others are short. In addition, every field has a name, called the field name.

FIELDS • In database management systems, a field can be required,optional, or calculated. • A required field is one in which datamust be entered. • An optional field may be left blank. • A calculated field is one whose value is derived from some formula involving other fields. You do not enter data into a calculated field; the system automatically determines the correct value. • A collection of fields is called a record.

Linking Tables The Orders to ItemsSold relationship enforces referential integrity. One Order can list many ItemsSold.

CELLS • In spreadsheet applications, a cell is a box with a single piece of data. • The data is usually text, a numeric value, or a formula. The entire spreadsheet is composed of rows and columns of cells. • A spreadsheet cell is analogous to a field in database management systems. • Individual cells are usually identified by a column letter and a row number. For example, D12 specifies the cell in Column D and Row 12.

FORMULAS • In spreadsheet applications, a formula is an expression that defines how one cell relates to other cells. • For example, you might define Cell C5 (Column C, Row 5) with the formula =A4*D7 which means multiply the value in Cell A4 by the value in Cell D7

DBMS • The information from a database can be presented in a variety of formats. Most DBMSs include a report writerprogramthat enables the output of data in the form of a report. • Many DBMSs also include a graphics component that enables the output of information in the form of graphs and charts.

Sample Report with Groups

QUERY LANGUAGE • Query - a specialized language for requesting information from a database. • For example, the query SELECT ALL WHERE age > 30 AND name = "Smith" requests all records in which the Name field is "Smith" and the Age field has a value greater than 30. • The de facto standard for query languages is SQL

E-Business Databases Order Form Descriptions Prices Web page Internet Customer Page request Web Server Web program script <HTML> Text <% Database connection %> Queries and data

Database Servers • Specially designed computers that hold the actual databases and run only the DBMS and related software • Usually multiprocessor computers, with RAID disk arrays used for stable storage • Connected to one or more servers via a high-speed channel • Hardware database accelerators are also used in large volume transaction processing environments

Database Servers • A database server is a computer or program running on a computer which provides database services to other programs or computers. They typically provide a complete database management system of some sort, even if limited to only basic database creation, repair and deletion. • An alternative approach is to build the support for the information storage directly into the programs which are using it. This is common on less powerful computer systems or for applications which don't have complex requirements. • In the Internet context, it's very common for web sites to have web servers delivering pages which have their core content stored in a database server.

Database Programs Used at ECU • MVS (for registering students), SQL (Structured Query Language), DB2 (Database 2), Oracle, Access, and more • ITCS is in charge of programming databases and keeping them up and running. • Network support is in charge of keeping the databases connected to the network. • Student, faculty, and staff data are automatically updated on server at input.

What is SQL? • SQL stands for Structured Query Language • Allows access to a database • Is an ANSI standard computer language • Can execute queries against a database • Can retrieve data from a database • Can insert new records in a database • Can delete records from a database • Can update records in a database • Is easy to learn

SQL • SQL is an ANSI (American National Standards Institute) standard computer language for accessing and manipulating database systems. • SQL statements are used to retrieve and update data in a database. SQL works with database programs like MS Access, DB2, Informix, MS SQL Server, Oracle, Sybase, etc. • There are many different versions of the SQL language • To be in compliance with the ANSI standard, they must support the same major keywords in a similar manner (such as SELECT, UPDATE, DELETE, INSERT, WHERE, and others).

ACCESS Access 2003 provides a powerful set of tools that are sophisticated enough for professional developers, yet easy to learn for new users. Create or use powerful database solutions that make organizing, accessing, and sharing information easier than ever. MICROSOFT ACCESS TOUR

On Monday, April 8, the United States will experience a total solar eclipse — a rare astronomical event where the moon passes directly between the sun and the Earth, blocking out the sun’s light almost completely. The last total solar eclipse in the contiguous U.S. was in 2017, and the next one won’t be until 2044.

If the weather cooperates, people across the United States — from northeastern Maine to southwestern Texas — will be able to observe the eclipse using protective eyewear. Those in the path of totality , where the moon entirely covers the sun, will have the best view, but 99% of people in the continental U.S. will be able to see a partial eclipse. Weather permitting, those on the MIT campus and the surrounding area will see 93 percent of the sun covered, with the partial eclipse starting at 2:15 p.m. and reaching its peak around 3:29 p.m. Gatherings are planned at the Kresge Oval and the MIT Museum , and a live NASA stream will be shown in the Building 55 atrium .

Brian Mernoff , manager of the CommLab in the Department of Aeronautics and Astronautics, is an accomplished astrophotographer and science educator. Mernoff is headed to Vermont with his family to experience the totality from the best possible angle — but has offered a few thoughts on how to enjoy the eclipse safely, wherever you are.

Q: What should viewers expect to see and experience with this solar eclipse?

A: When you’re watching TV (the sun) and your toddler, dog, or other large mammal (the moon) blocks your view, you no doubt move over a bit to try to get a partial or full view of the TV. This is exactly how the path of totality works for an eclipse. If you are exactly in line with the moon and sun, it will be completely blocked, but if you start moving away from this path, your view of the sun will start to increase until the moon is not in the way at all.

The closer you are to the path of totality, the more of the sun will be blocked. At MIT, about 93 percent of the sun will be blocked. Those in the area will notice that things around you will get slightly darker, just like when it starts to become overcast. Even so, the sun will remain very bright in the sky and solar glasses will be required to view the entirety of the eclipse. It really goes to show how incredibly bright the sun is!

Within the narrow path of totality, the moon will continue to move across the sun, reaching 100 percent coverage. For this short period of time, you can remove your glasses and see a black disk where the sun should be. Around the disk will be wispy white lines. This is the corona, the outermost part of the sun, which is normally outshone by the sun’s photosphere (surface). Around the edges of the black disk of the moon, right as totality begins and ends, you can also see bright spots around the edges, known as Bailey’s Beads, caused by sunlight shining between mountains and craters on the moon.

But that’s not all! Although you will be tempted to stare up at the sun throughout totality, do not forget to observe the world around you. During totality, it feels like twilight. There is a 360-degree sunset, the temperature changes rapidly, winds change, animals start making different sounds, and shadows start getting weird (look into “shadow bands” if you have a chance).

As soon as totality ends, and you start to see Baily’s Beads again, put your solar glasses back on as it will get very bright again very fast as the moon moves out of the way.

Q: What are the best options for viewing the eclipse safely and to greatest effect?

A: No matter where you are during the eclipse, make sure you have solar glasses. These glasses should be ISO-approved for solar viewing. Do not use glasses with scratches, holes, or other damage.

If you are unable to obtain solar glasses in time, you can safely view the eclipse using a home-made projection method , such as a pinhole camera or even projecting the image of the sun through a colander.

The best view of the eclipse will be from within the path of totality, but even if you are not within it, you should still go outside to experience the partial eclipse. Use the NASA Eclipse Explorer to find the start, maximum, and end times, and then find a nice spot outside — preferably with some shade — put on your glasses, and enjoy the show.

For a closer view of the sun, find a friend that has a telescope with the correct ISO-certified solar filter. This will let you see the photosphere (or chromosphere if it is an H-alpha scope) in a lot more detail. If you do not have access to a telescope, NASA plans to livestream a telescope view throughout the eclipse. [The livestream will be displayed publicly on a large screen in Building 55 at MIT, rain or shine.]

The only time you can look at or image the sun without a filter is during 100 percent totality. As soon as this period is done, glasses and filters must be put back on.

After the eclipse, keep your glasses and filters. You can use them to look at the sun on any day (it took me an embarrassing amount of time to realize that I could use the glasses at any time instead of lugging out a telescope). On a really clear day, you can sometimes see sunspots!

Q: How does eclipse photography work?

A: This year I plan to photograph the eclipse in two ways. The first is using a hydrogen-alpha telescope. This telescope filters out all light except for one wavelength that is given off by hydrogen. Because it blocks out most of the light from the sun’s surface, it allows you to see the turbulent upper atmosphere of the sun, including solar prominences that follow magnetic field lines.

Because this telescope does not allow for imaging during totality as too much light is blocked, I also plan to set up a regular camera with a wide-angle lens to capture the total eclipse with the surrounding environment as context. During the 2017 eclipse, I only captured close-ups of the sun using a regular solar filter and missed the opportunity to capture what was going on around me.

Will it work? That depends on if we get clear skies, and how many pictures of my 1.5-year-old need to be taken (as well as how much chasing needs to be done).

If you would like to take pictures of the eclipse, make sure you protect your camera sensor. The sun can easily damage lenses, sensors, and other components. Here are some examples of solar damaged cameras . The solution is simple, though. If using a camera phone, you can take pictures through an extra pair of solar glasses, or even tape them to the phone. For cameras with larger lenses, you can buy cardboard filters that slide over the front of your camera or even buy ISO-approved solar film and make your own.

Q: Any fun, unique, cool, or interesting science facts about this eclipse to share?

A: If you want to get even more involved with the eclipse, there are many citizen science projects that plan to collect as much data as possible throughout the eclipse.

NASA is planning to run several experiments during the eclipse , and researchers with MIT Haystack Observatory will also be using four different technologies to monitor changes in the upper atmosphere , both locally and across the continent.

If you are interested in learning more about the eclipse, here are two of my favorite videos, one on “ unexpected science from a 0.000001 megapixel home-made telescope ” and one on solar eclipse preparation .
