  • Achieving consistency and synchronization among multiple data stores that cooperate within a single system in the absence of transaction monitoring
    Patent number: 6226694
    Abstract: A system and method synchronizes multiple data stores and achieves data consistency in a non-transactional multiprocessing computer system. Processes are paused and later resumed according to their position in a dependency tree of the system. The data input sources of the system are in effect disabled and any data flow currently in progress in the system is flushed out the various data flow paths to the different data stores. When this process is complete, each of the multiple data stores is synchronized and the data is in a consistent state.
