Hello, If you want to build a client/server database where : Server : somewhere on the network, Client : needs to have a quasi realtime "mirror" from the main database in its own client memory. They need to have the data in their own memory, because the clients need to be able to perform very fast lookups in the table. I am really looking for a 'smart' system, so not one where I do a refresh every x seconds. I investigated to do it with ADO components, but aparently there does not seem to be any trigger mechanism from the server to the client to indicate that records were changed/inserted/deleted. Is Interbase maybe a solution ? Can anyone give me a clue about where to start ? Thanx.
