SharePoint Lessons Learned – Don’t forget to use proven design patterns and practices(Via Hugo)

“SharePoint should be seen as another layer in the technology stack that your code will interact with. But just because you are using this layer you should not forget to follow good and proven design practices. The following points describe some of the principles that sometimes seem to be forgotten when using SharePoint:

1. Create a data access layer to access your lists.

After all you would be doing this if you were programming against a database table so why not do the same for a SharePoint list. The last thing you want is to have several components of your application accessing the same list in several different ways. If the list schema, name or location changes then you would need to change the code in every component that uses that list (this could be acceptable for small proof of concept applications but not for enterprise applications). In a future post I'll be giving an example of designing and coding a simple SharePoint data access layer.”
