Recently we had an interesting thread about the realtive qualities of Hibernate and CMP.
One of the points that I picked up from the discussion, is that if you are only using CMP entities for persistent O/R based objects, then lightweight systems like Hibernate may provide a better and faster alternative. As Hibernate and CMP offer similar features in this area, it got me thinking whether it would be possible to have a pattern where you could use either system interchangeably as an implementation. So for example, you abstract the specifics of both technologies behind a Facade pattern. Depending on what implementation you use (Hibernate, CMP or another), you merely uses different implementations of the Facade. This would only be practical to do if you are using some sort of code generation system such as XDoclet or XSLT. The Facade would abstract the jobs of finding, creating and deleting instances of persistant objects. Does anyone else think this type of pattern would be useful? Or does it sound like science fiction? -- Peter Beck BEng (hons) - Managing Director, Electrostrata Ltd. http://www.electrostrata.com --+-+-- Experts in e-business and e-commerce ------------------------------------------------------- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
