Introduction:
MongoDB is an open-source, NoSQL database system that stores data in a flexible JSON-like format called BSON (Binary JSON). It uses dynamic schemas, meaning that, unlike relational databases, MongoDB does not require a predefined schema before you add data to a database. You can alter the schema at any time and as often as necessary without having to set up a new database with an updated schema. It is designed to handle large volumes of data and provides high performance for both read and write operations. Developers and organizations deal with large and evolving datasets and use MongoDB for its scalability, flexibility, and ease of use.
Steps:
- Go to www.mongodb.com and navigate to the community server section.
- Select the version of MongoDB Community Server-7.0.11
- Select Windows system -x64.
Select .msi and click Download.
2. Click Next on the MongoDB setup wizard.
3. Check the box in the end-user license agreement and click Next.
4. Check the box for Install MongoD as a service and click Next.
5. If you want to install MongoDB Compass, check the box. Otherwise, uncheck the box and click on Next.
MongoDB Compass: MongoDB Compass is a graphical user interface (GUI) tool provided by MongoDB to interact with MongoDB databases. It allows developers and database administrators to visually explore their data, run ad hoc queries, manage indexes, and perform various other tasks related to MongoDB databases.
6. Click Install to begin the installation.
7. Click Finish on the Installation Setup Wizard.
8. Click on Downloads, select the folder, and you can see Windows Installer.
9. Now, go to C drive, select Program files, and click on MongoDB.
10. Select Server.
11. Select 7.0 (version).
12. Select bin.
13. Click on the drop-down arrow and select the path
C:\Program Files\MongoDB\Server\7.0\bin
14. Search Environment Variables, you will see Edit the system environment variables (Control Panel) and select Open.
15. Click on Environment Variables in the System Properties window.
16. Select the path and click OK.
17. Select New, copy the path, and click OK.
18. Now, install MongoDB Shell. MongoDB Shell is required to interact with MongoDB Server. Go to the Google search bar and type MongoDB shell; it will automatically take you to the MongoDB website.
MongoDB Shell: MongoShell, also known as the MongoDB Shell or simply Mongo, is an interactive JavaScript interface to MongoDB that allows developers and administrators to interact with MongoDB instances directly through a command-line interface (CLI). It’s a powerful tool that provides a way to perform various operations, such as querying and updating data, managing indexes, and executing administrative commands.
- Select the latest version, 2.2.9.
- Select the platform (x64).
- Select the package-.msi. Click on Download.
19. Go to Downloads, open the folder, and click mongosh-2.2.9-x64.
20. Click Next on MongoDB Shell Setup Wizard.
21. Uncheck the box and click Next on MongoDB Shell Setup.
22. Click Install on MongoDB Shell setup.
23. Click on Finish to complete the installation.
24. Now, cmd prompt in the search bar, select Command Prompt and select Open to check MongoDB and Mongo shell installations.
25. Type mongod –version in the command prompt.
Command: C:\Users\Drushti 5>mongod --version
26. If the MongoDB installation is successful, we get a message as shown below.
It will show the version as V7.0.11.
27. Go to Command prompt again and type mongosh.
Command: C:\Users\Drushti 5>mongoshIf mongosh installation is successful, we get a message as shown below.
28. We can test it by typing the command show dbs (it shows all the databases that are currently available on the MongoDB server).
Command: test> show dbs
29. The image below shows the successful mongosh installation and the databases that are currently available in MongoDB:
To create a new database, type use ss (ss is the name of the new database).
Command: test> use ss
Now, it switches to the new database, which is SS.
30. To create the collection in the current database, type db.createCollection(“students”).
Command: ss> db.createCollection(“students”)
A message is displayed saying that 1 collection is created in the MongoDB.
{ok:1}
We can work on MongoDB by giving different commands.
FAQs
Q1. What is the concept of MongoDB?
Answer: MongoDB is a non-relational document database that provides support for JSON-like storage. The MongoDB database has a flexible data model that enables you to store unstructured data, and it provides full indexing support, and replication with rich and intuitive APIs.
Q2. What is MongoDB mostly used for?
Answer: MongoDB is built on a scale-out architecture that has become popular with developers of all kinds for developing scalable applications with evolving data schemas. As a document database, MongoDB makes it easy for developers to store structured or unstructured data. It uses a JSON-like format to store documents.
Q3. Which database is used in MongoDB?
Answer: MongoDB is a NoSQL distributed database program. Because data doesn’t need to fit within the confines of a strict relationship, MongoDB can operate as a general data store. This database provides several advantages. In this type of database, data is stored in MongoDB and maps to a flexible schema.
Q4. Which tool is best for MongoDB?
Answer: Studio 3T is also the only MongoDB tool that has an SQL migration feature and is compatible with all major SQL databases. This makes it easy for teams to move from SQL to MongoDB. Unlike other GUIs, it also lets you import an entire database, preview documents, and customize table-to-JSON relationships.
Q5. What data type is MongoDB?
Answer: MongoDB uses JSON documents to store records. However, behind the scenes, MongoDB represents these documents in a binary-encoded format called BSON. BSON provides additional data types and ordered fields to allow for efficient support across a variety of languages.
