The IDal interface provides methods that utilise the ADO.NET architecture in a vendor neutral way. The same code is written wether you are accessing a SQL Server database, an OLEDB compliant database, or an ODBC compliant database. This makes your code more portable and easier to maintain. The best thing overall is that less code has to be written and so less to maintain and debug
Objects returned via the GetDAL method support data access best practices with late opening of database connections and early closing to provide a more scalable solution.
|DALFactory||A factory class that creates objects that implement the IDal interface.|
