Improving Scalability and Performance of Application

Abstract

Now-a-days, most of the enterprise and web application is using the conventional database which is Oracle DB. Oracle Database is uses a table structured data storing methodology. Because of that accessing tables to get the relevant data will be faster. But if the table column needs to be updated or a new column needs to be added then it adds up extra queries and additional work to the developer. MongoDB is an open-source document database, and leading NoSQL database. MongoDB is written in c++ . MongoDB is a cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on concept of collection and document. Collection is a group of MongoDB documents. It is the equivalent of an RDBMS table. A collection exists within a single database. Collections do not enforce a schema. Documents within a collection can have different fields. Typically, all documents in a collection are of similar or related purpose. A document is a set of key-value pairs. Documents have dynamic schema. Dynamic schema means that documents in the same collection do not need to have the same set of fields or structure, and common fields in a collection's documents may hold different types of data.AngularJs is advanced javascript which helps in many ways to access the mongodb directly from the front end. And it help the application to gain scalability and performance.
