5. 1. Go to http://www.mongodb.org/downloads
Click on Community Server link. Then you will find
like below for windows.
Download and install it .

6. 1. Go to C drive if you have installed mongodb in c drive.
2. Create folder db inside data. (c:datadb)
3. Open command prompt.
4. Type mongod. Server will start on port 27017.
5. Open another command prompt.
6. Type mongo
Now you are ready to do CRUD operations.
We will use test database which is by default.

7. CRUD means Create, Read, Update, Delete
Create Operations
Create or insert operations add new documents to
a collection. If the collection does not currently exist,
insert operations will create the collection.

8. Syntax for read or query documents:
db.COLLECTION_NAME.find()
Example:
db.mycollection.find();

9. Method for update documents:
Syntax:
db.COLLECTION_NAME.update(SELECTIOIN_CRITERI
A, UPDATED_DATA)
Example:
db.mycollection.update({name:’Anand’},{$set:{name:’ak’}});

10. Method for delete documents:
Syntax:
db.collection_name.remove (DELETION_CRITERIA)
Example:
db.mycollection.remove({name:’ak’});
