I need to replicate data from one master table to another table on a similar database in real time, both have the same structure.Every insert and update on the master table will be replicated to the second table.
Users will be able to add data to the second table on a different key range so we'll have no problems while integrating data from the master table. Data from the second table will never be pushed back to the master.
What is the easiest way and cost-effective way to do this, without using dynamic sql : - we have thougt about triggers and scripts but miss time to develop them - I have just discovered about updatable materialized view which should do the trick? If I understand it seems to allow to update my second table, and to allow users to update and add data to the second table. But every documentation I read talks about data being pushed back to the master if it doesn't exist on the master: is it mandatory or not? Is it possible to make a one-way updatable materilized view and how? How is there another technical solution which would be better?
Thanks in advance for your advice and your help, liz
