A MongoDB connection contains relational schemas which are transformed from the collection schemas in a MongoDB data source. MongoDB uses BSON as the data storage and network transfer format for documents in collections. Designer supports extracting of the metadata from the documents of a collection, and transforming schemas to relational tables. You can then add the collections and tables to the MongoDB connection from the transformed relational schemas and tables, and access them in the same way as JDBC-supplied tables. Designer supports MongoDB 1.8 and above.
