We have an accouting system that put its data in a sql server database. I would like to integrate another (billing) system of our, using the same database. For this to work, I guess I need to know wich tables and columns our accounting system uses and edits when transaction is putted in manually in the accounting system. Is there an easy way to monitor, or in some way recording the changes done in a database so I know where our billing program should write its data.
