 # Short-Description: An object/document-oriented database
 # Description:       MongoDB is a high-performance, open source, schema-free 
 #                    document-oriented  data store that's easy to deploy, manage
 #                    and use. It's network accessible, written in C++ and offers
 #                    the following features:
 #                    
 #                       * Collection oriented storage - easy storage of object-
 #                         style data
 #                       * Full index support, including on inner objects
 #                       * Query profiling
 #                       * Replication and fail-over support
 #                       * Efficient storage of binary data including large 
 #                         objects (e.g. videos)
 #                       * Auto-sharding for cloud-level scalability (Q209)
 #                    
 #                    High performance, scalability, and reasonable depth of
 #                    functionality are the goals for the project.
