# 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.
