The OGSA-DAI Trigger component provides a mechanism to notify an OGSA-DAI server when a table in an SQL database has had its rows modified. It then executes a stored OGSA-DAI workflow to perform an action based on the notification. The trigger also provides the old and new values for the modified row which allows specific actions to be taken based on the exact database changes. These actions can use the full range of access, transformation, and delivery functionality available in OGSA-DAI.

Changes:
An example Scenario was added to illustrate how the triggers could be used with OGSA-DAI. A crash in the .dll caused by incorrect deallocation of a null pointer was fixed. Many updates and fixes were made to the documentation.
