Claim 14

The apparatus of claim 9, wherein the unit of work request is coordinated by requests selected from a group comprising prepare, commit, rollback, precompletion, and postcompletion.

Claim 15

The apparatus of claim 8, wherein the instance manager comprises means for controlling a datastore manager for the external non-object-oriented datastore by issuing one or more commands selected from a group comprising an open command and a close command.

Claim 16

The apparatus of claim 8, wherein the schema mapper comprises means for translating queries to specific instructions for a datastore manager for the external non-object-oriented datastore, wherein the instructions are selected from a group comprising a select instruction, an insert instruction, an update instruction, and a delete instruction.

Claim 17

A program storage medium readable by a computer having a memory, the medium tangibly embodying one or more programs of instructions executable by the computer to perform method steps for managing datastore persistent objects and datastore collections in an object-oriented environment, the method comprising the steps of: creating one or more datastore persistent objects in a memory of the computer, wherein the datastore persistent objects encapsulate logical units of data retrieved from an external non-object-oriented datastore stored on a data storage device coupled to the computer; creating one or more schema mappers associated with the datastore persistent objects in the memory of the computer, wherein the schema mappers translate common elements between the logical units of data retrieved from the external non-object-oriented datastore and the datastore persistent objects; creating one or more datastore collections in the memory of the computer for organizing the datastore persistent objects; and tracking the datastore collections, schema mappers and datastore persistent objects in the memory of the computer using an instance manager.
