The RDBMS backend allows you to map relational database tables, projections thereof, as well as arbitrary parametric SQL queries onto PowerLoom relations. Querying these relations in PowerLoom (either directly or during backward inference) then calls out to the database to bring in relevant data. Known bindings on the PowerLoom relation translate dynamically into appropriate WHERE constraints (e.g., during inference). This is useful to deal with large datasets or to build a simple deductive layer on top of a database. There is also some limited support to map PowerLoom assertions onto database table updates. We currently support MySQL and Oracle through a variety of different access interfaces (depending on whether this runs in Lisp, C++ or Java). The bad news (for you :-) is that we haven't released this yet. This is more or less ready but needs a bit more packaging and documentation. Releasing this has been on the TO DO list for a while, we just haven't gotten around to it yet.
