Creating an OLE DB Driver for SQL Server application involves these steps:
- Establishing a connection to a data source.
 - Executing a command.
 - Processing the results.
 
Note
When possible, use Windows Authentication. If Windows Authentication is not available, prompt users to enter their credentials at run time. Avoid storing credentials in a file. If you must persist credentials, you should encrypt them with the Win32 cryptoAPI.
