BaseTen, a new Mac framework for PostgreSQL databases
Posted on 2007-01-02
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)
- Foundation, Mac OS X 10.4-era and later; PostgreSQL 8.2 and later
- AppKit for the optional BXSynchronizedArrayController
