MongoDb Tutorial For Beginners

 

MongoDB is a free and open-source document-oriented database program. It uses a document-oriented data model and a non-relational, or NoSQL, data management system. Here is a tutorial for beginners to get started with MongoDB:

1. Install MongoDB on your system by following the instructions provided on the MongoDB website.

2. Once you have MongoDB installed, open a command prompt and navigate to the location where you installed MongoDB.

3. Start the MongoDB server by running the command "mongod" in the command prompt.

4. Open a new command prompt and navigate to the location where you installed MongoDB.

5. Start the MongoDB shell by running the command "mongo".

6. To create a new database, use the command "use [database name]". For example, "use mydb".

7. To create a new collection (similar to a table in a relational database), use the command "db.createCollection('[collection name]')". For example, "db.createCollection('users')".

8. To insert data into a collection, use the command "db.collection_name.insert({data})". For example, "db.users.insert({name: 'John', age: 25, location: 'New York'})".

9. To query data from a collection, use the command "db.collection_name.find()". For example, "db.users.find()".

10. To update data in a collection, use the command "db.collection_name.update({query}, {data})". For example, "db.users.update({name: 'John'}, {$set: {age: 30}})".

11. To delete data from a collection, use the command "db.collection_name.remove({query})". For example, "db.users.remove({name: 'John'})".

This is a basic tutorial to get you started with MongoDB. There are many other commands and features available, and you can learn more by reading the MongoDB documentation.
