title: Communication Between 2 Databases
body: <p>I have 2 databases and want to implement triggers on table update of database1 to do do some updates on database2's tables.</p>
  
  <p><strong>Example</strong>:<br>
  db1 has a table 1t1 <br>
  db2 has a table 2t1 <br>
  on inserting  a touple into 1t1 i want to insert corresponding touple into 2t1
