Download BaseTen for Mac - Cocoa database framework for working with PostgreSQL databases. MacUpdate Mac Libraries Software Downloads

DESCRIPTION

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

The BaseTen 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)

WHAT'S NEW

Version 1.7:

Features
- Database metadata fetching has been rewritten and is now much faster.
- BaseTen-specific SQL tables and views have also been optimized to require a smaller number of queries when making a connection.
- Queries sent after receiving change notifications from the database have also been made simpler.
- Database metadata is now shared across database contexts.
- Thread safety in metadata classes.
- Query logging is possible again. Query results are logged as well.
- Rewrote most parts of generic connection panel implementation. The panels should now work more reliably.
- Host existence is now checked before asking the user for login credentials.
- BXSynchronizedArrayController now sets created objects' foreign key fields if its content is bound to another synchronized array controller.
Bug fixes include:
- BaseTen
  - Self-updating collections now work even if they were initially empty.
  - Reconnecting after system sleep no longer requires SSL if set to prefer.
  - Password will only be stored into the Keychain if it's known to work.
  - Importing entities with equal names from an Xcode data model now works.
  - BaseTenModifications.sql is now included in the framework bundle.
  - More errors are reported, such as fetching from an inexisting entity.
- BaseTenAppKit
  - User-supplied IPv6 addresses are now handled correctly.
- BaseTen Assistant
  - SQL syntax in certain queries.
  - Helper tables are now removed before replacing entities.
  - Making changes to an Xcode data model no longer requires the assistant to be restarted.
  - Port number field now accepts an empty value after it has been filled once.
  - The main window's position is now stored into preferences.
  - The assistant's help now works.
