Answer 1

1つの提案：あなたのRDBMS

- Create triggers for each of your listening tables, this trigger 
should base on a new change on these table to update information to 
somewhere else 

- Create a table (named: datalogger)to store the data come from the trigger above, for example, when table1 has new record inserted, the 
trigger (named: trigger1) on table1 will be execute by RDBMS, then 
trigger1 will insert a new record into datalogger which describes 
the action event is "inserted", table name is "table1", and the 
inserted record id is "new_recordId" as example. The same process 
need to be applied for modifying action. 

- On your application, create a job, which will try to query the datalogger table periodically, (1ms, 10ms,... as your requirement) 
to find is there a new record in that table, if any, read the new 
record and find out what happened with your database based on the 
new record (determine by time or auto-increment id,..)
