Hi, first of all, I want to tell you that a lot of us have been in the same situation. When I converted my paradox apps to multiuser I got lots of problems, the paradox lock file isn't so good to get multiuser environments. Finally I had to port them to client server, so I recommend you to port your application to a client server architecture, (firebird is a good solution). If you want to (or have to) keep the paradox backend, then you could use a n-tier architecture (only one app access the paradox data, then it serves it to the clients). This is much more difficult than porting your app to client/server with firebird. > - Can we handle 5 to 6 Node thru Parodox for building Robust > Applications ? I know one multiuser paradox app working with 5 clients, but it isn't an easy task, and needs more maintenance than a client/server one. > - Is there any alternate solutions for getting a solution ? Any client/server aproach or n-tier architecture. > - Will Interbase backend fit for my Proposal? Of course, but give a look at Firebird (free version of interbase). I am handling tables with 200.000 records and lots of users simultaneusly without problems. > > - Is there any books or Technical articles for builing Multiuser > applications(If so please give me the target). There are a lot of books and documents, a simple search in google about "firebird delphi" will give you a starting point. A good printed book is "The dark side of delphi" since it handles the options. One more thing, if you don't plan to change your database (eg. firebird ) to another one in a future, use specific components like IBObjects, because they will give you more performance than BDE components. good luck ;) -- un saludo Dario Guerrero [EMAIL PROTECTED] ----------------------------------------------------- Home page: http://groups.yahoo.com/group/delphi-en/ To unsubscribe: [EMAIL PROTECTED] Yahoo!
