Document database implementation with MongoDB

We are now going to work on refactoring our RDBMS implementation—with JPA as our ORM provider—into a document database implementation, using MongoDB as our underlying database provider. MongoDB (from humongous) is a free and open source cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemas. MongoDB is developed by MongoDB Inc. and is located at https://github.com/mongodb/mongo.
