MADlib source code is organized such that the core logic of a machine learning or statistical module is located in a common location, and the database-port specific code is located in a ports folder.  Since all currently supported databases are based on Postgres, the postgres port contains all the port-specific files, with greenplum and hawq inheriting from it.  Before proceeding with this guide, it is recommended that you familiarize yourself with the MADlib module anatomy.
