We can ascertain compliance without looking at the contents of the database. Our system can function as a drop-in addition to an existing database system, adding additional functionality in a robust manner. The policies are written in the AIR language, and the reasoners and wrapper scripts in C++ and Python. We discuss the design and implementation of this system in detail.</dim:field>
