Using MongoDB removes the complex object-relational mapping (ORM) layer that translates objects in code to relational tables. MongoDB's flexible data model also means that your database schema can evolve with business requirements.
There are several persistent frameworks and ORM options in Java. A persistent framework is an ORM service that stores and retrieves objects into a relational database.
Object-relational mapping (ORM) techniques make it easier to work with relational data sources and can bridge your logical business model with your physical storage model. Follow this tutorial to integrate connectivity to MongoDB data into a Java-based ORM framework, Hibernate.
Before you start using MongoDB in your Java programs, you need to make sure that you have MongoDB CLIENT and Java set up on the machine. You can check Java tutorial for Java installation on your machine. Now, let us check how to set up MongoDB CLIENT. You need to download the jar mongodb-driver-3.11.
There are some. Start reading:
