Real-world persistence: Chameleon Persistence

Chameleon Persistence is a different persistence engine. It can be used for JavaBeans (in a classic O/R style), XML or other formats and is not constrained by traditional O/R requirements. Full native query language and complex query requirements are fully supported.

Features:

• Designed for real enterprise needs
• Not tied to JDBC-based databases
• Cross data store retrievals (the object graph is spread across databases)
• Very flexible data mapping (with or without JavaBeans)
• Not limited to JavaBean persistence
• Native data store query language support
• Minimum configuration for minimum use cases
• Expressions and scripts for query parameter substitution
• Client-Server architecture
