I've been working on a database schema management system for the past six months. All approaches I've investigated fell short in one aspect or another. Support for branching is a big concern. Also, none of the solutions I've investigated made any distinction between tables and programmables. Concurrent changes are also important. I've written a 2-tier java swing app that manages a repository of database artifacts, by organizing them into projects. The design in inspired by industry standard versioning techniques and is artifact driven. I've made a lot of progress; I am putting the finishing touches on the oracle schema import feature. It will import and provide a base-line for tables, constraints, indexes, views, functions/sps, packages, and sequences... More work remains, certainly. http://picasaweb.google.com/lh/photo/RmLccBaZbI5_f3fVwCiSNtdGpmyed42E2H64xNBONNA?feat=directlink
