Pathfinder

Relational optimiser and code generator.

The library provides FFI bindings to the Pathfinder relational optimiser and code generator. Specifically, the library allows for

• optimisation of table algebra (a variant of relational algebra) expressions

• and compilation of table algebra expressions into SQL:1999 queries

Note that the C source bundle of Pathfinder is also included in this package. The C sources are automatically built along with the Haskell FFI bindings. There is no need to download and install Pathfinder separately.
