----------------------------------------------------------- From: Sijin Message 2 in Discussion Hi Bisht, First of all DB independent apps tend to fizzle out after a certain scale. So if you are going in for a medium to enterprise level project, i would suggest that you stick to one DB provider. Now coming to your question, First of all you need to make your DB layer in your code DB independent. I would suggest looking at the Microsoft Data Access Application Block (Abstract Factory) , It is a DB helper Application block which uses the AF pattern to abstract DB ops. For the configuration part you can use either XML config files or the registry to determine which conn. string to use to connect to the DB. One thing you will need to take care of is that there a lot of inconsistencies between the DBs itself, so you must test your DB implementations on all supported DBs before going ahead. Incompatibilities may arise in type definitions SP support, auto numbering etc. Sijin Joseph http://www.indiangeek.net http://weblogs.asp.net/sjoseph ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/BDOTNET/_emailsettings.msnw Need help?
