Make entity engine a standalone database access tool/API
--------------------------------------------------------

                 Key: OFBIZ-4153
                 URL: https://issues.apache.org/jira/browse/OFBIZ-4153
             Project: OFBiz
          Issue Type: Improvement
          Components: framework
            Reporter: Raj Saini
            Priority: Minor


From the user mailing list:

I was picturing the entity engine as a lower level artifact - like a jar file. I don't have all of the details worked out yet, but what I picture is this:

1. An application needs a database-agnostic data store.
2. The application accesses the data store though the entity engine API/ jar library.

Ofbiz has a very convenient way of defining databases, tables, and views as XML files. Plus, it has the ability to create/modify table/index structures during start-up. I believe that would be a very handy tool for anyone wanting to create any application that requires data storage.

Wrapping the entity engine jar file in an OSGI bundle would be trivial.

If anyone is interested in exploring this further, then they should create a Jira issue and we can take it from there.

Adrian Crum commented on OFBIZ-4153:
------------------------------------

Some preliminary work was done on this idea in a branch:

https://svn.apache.org/repos/asf/ofbiz/branches/executioncontext20090716

That branch is a little old, and the changes in it encompass more than just the entity engine, but it should provide some general direction for this effort.
