BaseTen is a new, open source Cocoa database framework for working with PostgreSQL databases. BaseTen has been designed with familiar, Core Data -like semantics and APIs.

The initial Developer Preview 1 release is intended for evaluation purposes only, but new versions should follow shortly. The feature highlights include:

• BaseTen Assistant imports Core Data / Xcode data models
• Discovers the database schema automatically at runtime, including 1-1, 1-many and many-many relationships
• Database changes are propagated to clients automatically, without polling
• In-memory database objects are uniqued, and objects fetched via relationships are faults by default
• Support for RDBMS features like database-driven data validation, multi-column primary keys and updateable views
• Autocommit and manual save/rollback modes, both with NSUndoManager integration
• A BaseTen-aware NSArrayController subclass automates locking and change propagation
• Fetches are specified with NSPredicates (the relevant portions of which are evaluated on the database)

Requirements:
PostgreSQL 8.2 or later
