How many violations are needing to be submitted at one time from the front-end? Or are you passing them to the database one-at-a-time? I am thinking table-valued parameters may be useful here to pass the data...but that is sort of an aside to the question being asked.
If it's one violation per call then SCOPE_IDENTITY() might be all you need. If it's more than that OUTPUT could most likely help you. Can you provide the DDL for the tables and sample data that you would send to the database that you would want committed to the four tables and linked accordingly?
