Lore is an object-relational mapping (ORM) implementation providing many features like prepared statements, (multiple) inheritance, a comfortable query syntax, highly customizable automated form generation, and result caching using memory mapping (MMap). It aims at performance, usability and - unlike most ORMs - high coverage of native SQL functions and features. Lore is currently using PostgreSQL as database backend.
