Features

- Supports JDO 1.0.1.
- Implements the entire JDOQL query language, including several useful method enhancements.
- Auto-creates all necessary schema elements (tables, foreign keys, indexes) according to your apps classes and JDO metadata.
- Auto-validates expected schema structure at runtime, reducing failures from schema evolution.
- Can map Java classes to SQL views, and allows for direct SQL queries, to leverage SQL capabilities not normally accessible through JDO.
- Designed to be lightweight and fast.

A practical introduction to TriActive JDO
Transparently persistent data regardless of the underlying data store

TriActive JDO (TJDO) is a lightweight, open source implementation of
Sun's Java Data Objects (JDO) 1.0 specification. With it, developers can
use a transparent persistence mechanism with any JDBC-compliant
database and any Java object. In this article, Java developer Jeff Gunther
provides an introduction to TJDO by demonstrating how a domain model
can be persisted to a MySQL database. In addition to illustrating specific
implementation details for TJDO, the article reviews the basic concepts
and components of the JDO specification.
