Oracle Workspace Manager

"Oracle Workspace Manager, often referred to as Workspace Manager, provides an infrastructure that lets applications conveniently create workspaces and group different versions of table row values in different workspaces. Users are permitted to create new versions of data to update, while maintaining a copy of the old data. The ongoing results of the activity are stored persistently, assuring concurrency and consistency. Oracle Workspace Manager can be installed on any computer with Windows operating system."
