title: Perform .NET Action on Database Change
body: <p>We have a process that needs to fire when a change occurs to a specific database table in Oracle. At the moment a similar process has been developed using triggers and a bunch of subsequent database actions that occur when that trigger is fired.</p>
  
  <p>However, in this solution we want to call a .NET component (most likely a service) when the change occurs to a row or bunch of rows in a database table. Now, you could implement a polling mechanism that will check the table at regular intervals for those modifications and then instantiate the service when it finds any. However, I would prefer a more event driven approach.</p>
  
  <p>I assume this is something that has been done elsewhere so I was wondering what approaches other people have used for dealing with such requirements?</p>
  
  <p>Thanks in advance</p>
  
  <p><em><strong>Edit</strong>: The process that fires when a change occurs to the underlying data is essentially a call to an external web service using some of the related data. I am beginning to think whether this call should occur as part of the same process that is submitting the data into the database, rather than being triggered by the data change itself.</em></p>
