Summary
Implemented a PostgreSQL interface (PGInterface). With the interface, it is possible to connect to polypheny via the PostgreSQL JDBC driver.
Changes
The interface is mainly isolated from the rest of the code, so apart from the new features, no changes to the existing architecture were done.
Features
Tests
The tests were implemented in the dbms module.
ToDo
There are several starting points for future work. Some major points of interest are listed below, and smaller ToDo's are marked in the code.
