Learn about Referenced Documents, Embedded Documents and how to model data in MongoDB in this tutorial.
To connect to the MongoDB database we are going to use a module called Mongoose. We will need to install mongoose module just like we did with express. Go to your terminal and enter the following command. npm install mongoose --save. This will install the mongoose model and add it as a dependency in our package.json.

A bunch of documents would then make up a collection in MongoDB. In this article, you will learn - How to Creating a database using “use” command; Creating a Collection/Table using insert() Adding documents using insert() command; Creating a database using “use” command. Creating a database in MongoDB is as simple as issuing the "using" command. The following example shows how this can be done.

Now, let's connect to our database. It is interesting to note that we don't need to create one. When Mongo sees that database doesn't exist, it will create it for us: DB database = mongoClient.getDB("myMongoDb"); Sometimes, by default, MongoDB runs in authenticated mode. In that case, we need to authenticate while connecting to a database. An Introduction to Mongoose for MongoDB and Node.js A Mongoose Model is then mapped to a MongoDB Document via the Model's schema definition. Once you have defined your schemas and models, Mongoose contains many different functions that allow you to validate, save, delete, and query your data using common MongoDB functions. I'll talk about this more with the concrete code examples to follow. MongoDB Delete Database - Tutorialkart.com
