Abstract
A Unit of Work object class for an object oriented database management system provides concurrent processing through Unit of Work levels and instances while maintaining the integrity of the data in the database. Each new Unit of Work assigned to a task is an instance of the Unit of Work object class. A Unit of Work manager controls each step such that manipulation of the data occurs to the copies at that particular level for that particular instance. Only after all levels have been completed satisfactorily will a 'Commit' occur to the data in the database. If completion is not satisfactory, Rollback of the levels occur, thus preserving data integrity. The Unit of Work manager can also switch control between Unit of Work instances, thus permitting simultaneous performance of tasks.
