ABSTRACT:
A data processing system includes at least one transaction processing application and a plurality of data managers which can be accessed by the transaction processing application. Each data manager is responsible for managing a separate data base. The system further includes a work-in-progress store and a work-in-progress store manager for managing the work-in-progress store. Whenever the transaction processing application instructs a data manager to perform an update, the data manager passes information concerning the update to the work-in-progress store manager which records this information in the work-in-progress store, and whenever the application completes a transaction, the data managers perform updates to their respective databases and the work-in-progress store manager is instructed to discard the contents of the work-in-progress store relating to this transaction.
