title: same code for different type database
body: <p>I am going to start an application in Asp.Net. In this app the database can be different but I want to use same C# code. That means for right now the database is SQL Server and its connection string will be defined in Web.Config file. But in later database may be MySQL or NETEZZA(IBM). But I want that only changing connection string but my C# logic should be same. How would I do it? Please suggest me. So For now I can not use any object of sql like SQLConnection or SQLCommand. I want to make it like generic.</p>
