Sitefinity 4 custom modules: OpenAccess necessary or not

With Sitefinity 4, is it a must to use OpenAccess, is it recomme开发者_如何学Pythonnded, or is it just an alternative option?

OpenAccess is the ORM used by Sitefinity, so it is certainly recommended and encouraged. However, if you are developing your own modules, user controls, etc and want to use your own data source you're free to do so. Check out this example on building a simple hello world module for Sitefinity 4 that doesn't use openaccess at all.

I hope this is helpful!
