"The Business Data Catalog allows structured data from line-of-business applications to be integrated into SharePoint in multiple ways through Web Parts, lists, people profiles, and search. Centrally managed connections to back-end systems can be defined once and then reused by end users to access back-end data without writing any code—easily making business data part of portal content. The Business Data Catalog also provides the ability for SharePoint Enterprise Search to integrate back-end business data into the search experience, without having to write any protocol handlers, iFilters, or custom code."
If you loved the Business Data Catalog feature in Sharepoint 2007, but don’t want to write the metadata needed to register the data sourde in sharepoint then check this post on Todd Baginski , it provides a tool which generate the metadata automatically with a nice interface.
