title: Free tool to watch database for changes?
body: <p>I'm looking for a tool that can watch database(mysql and oracle) for changes.</p>
  
  <p>When someone inserts or updates something in any(or chosen) table i want to get to know about it. It could be very useful for working with others people code that do some magic in database.</p>
  
  <p>I know that it can be done using triggers (<a href="https://stackoverflow.com/questions/167254/watching-a-table-for-change-in-mysql">see this question</a>), but I'm more interested in some tool that can do it, something free.</p>
