Abstract
The present invention relates to systems and methods for employing a trigger based mechanism to detect changes in a database table, providing a notification when the database table changes and registering to receive the notification. The systems and methods employ a listeners table to store information associated with registered database tables. Alter a database table changes, a trigger mechanism associated with the database change facilitates a search of the listeners table for a parameter associated with the changed database table. If the changed database table is registered, the information from the listeners table is provided to a delivery service which transmits a message indicating the registered database table changed. After receiving the message, a notification runtime service can route a notification to a client(s) registered to receive the notification. The foregoing mitigates performing time intensive queries and utilizing inconsistent query results.
