Can I use Hibernate for partial database migrations?
Posted on 2011-03-06
a hibernate newbie with a question:
I have an oracle database that is used in a client-server application (using Delphi).
I plan to migrate to a Java EE / Spring architecture using Hibernate as a persistence framework.
For this I would reverse engineer the existing oracle database (probably using hibernate tools in eclipse, this is ok and not part of the questions here)
And I would like to continue running the legacy system against the database.
The plan is to migrate one usergroup after another to the new architecture, this to avoid having to migrate the whole application at once.
* is this coexistence of one database running with the legacy CS application AND the new hibernate-based application possible? Do you see problems? Where? Any particular points to consider in Hibernate?
* what have other readers done to solve a similar problem?
* Do you see alternatives to Hibernate (in the java world, if possible using the Spring framework)?
Big questions, important questions, hence 500 points :)
Thanks a lot & regards,
