For installing MongoDB, you can either download the installation package from here or you can use mLab, a cloud database service that hosts MongoDB databases. After installing you will get a connection string which is used to connect with the database. The connection string contains the server name, port number, database name and an optional user name, password and connection specific options. While using Mongoose we have to create models for each collection (table), where we can specify the property name, type, validations (if any) etc. Mongoose will validate the collection while inserting the data into the database. So if you are developing a complex application or an application which requires manipulations while inserting and retrieving data, Mongoose is recommended over MongoJS since it has many useful features like object mapping, model validations, wide range of query filters for fetching data etc. which will make the development much more easier.
Integration of MongoDB with Node.js is really easy, especially with the node packages like MongoJS and Mongoose. In an agile development model where the requirements change too often, working with a NoSQL database like MongoDB will save a lot of development time since the developers don’t have to change the database schema or constraints for every amendment. Here the developers can concentrate more on the application logic without worrying too much about the database which will make the development process quick and more flexible.
