Ode Triggers: Monitoring the Stock Market

The Ode object‐oriented database provides sophisticated trigger facilities. We illustrate their use and capabilities by writing a non‐trivial trigger application–a stock market monitoring application. We will then describe our experiences in using the Ode trigger facilities to build the stock monitoring application. Our experiences with the performance and expressiveness of Ode triggers reveal advantages and limitations of the current system. Finally, we propose future work to remove the limitations. ©1997 by John Wiley & Sons, Ltd.
