Relational databases are used store financial records, keep track of inventory and to keep records on employees. In a relational database, information is stored in tables. The expensive of setting up and maintaining the database system Advances in the complexity of information databases have limits on field lengths and type. Mongo DB is a cross-platform document-oriented database program, Classified as a NoSQL database program and Mongo DB uses JSON-like documents with schema. It is non relational database technologies which arose under the NoSQL banner for use in big data applications and other processing jobs involving data that doesn't fit well in a rigid relational model Document databases store semi-structured data and descriptions of that data in document format. They allow developers to create and update programs without needing to reference master schema. Document databases are used for content management and mobile application data handling. Mongo DB has developed a tried and tested approach to constructing an Operational Data Layer. This process for constructing an Operational Data Layer has been successfully implemented with many customers. A successfully implemented ODL is a springboard for agile implementation of new business requirements.
