For re-running an application as it was released some time ago you'll need not only the rules but also Java classes and, possibly, other files, e.g., data tables. The Java stuff is bound to be more than just the data model as you might have it in Guvnor.<br>
<br>So, full Configuration Management usually has to deliver more that Guvnor (as far as I know) is ready to provide - or else it would compete with svn, git and whatnot.<br><br>A term like "snapshot" is usually different from "release", and the use case presented by our banker is based on releases. Otherwise they'd be in trouble.<br>

@Ansgar, it looks like you are doing in a database the work that it's<br>
being done by Guvnor, that keeps a lot of meta data for all the<br>
snapshots and it's ready to keep the snapshots forever, exposing them<br>
via a service, so you applications can get the right version. In the<br>
same way that you mention just knowing the ID of the snapshot that<br>
it's required.<br>
Using Guvnor, there is no need to remove snapshots, each snapshot will<br>
only contain the rules associated with it and not a complete<br>
application.<br>
