SharePoint 2007 - Business Data Catalog
I may have a need to use the Business Data Catalog (BDC) to import some data into SharePoint but don't really have the time to learn the syntax for the Application Definition file. Todd Baginski and Nick Swan have created a tool called BDC MetaMan that can be used to generate these files.
I am going to try it out for my needs and will be posting more about what I am using it for soon (provided what I am trying to do works...)
Check it out!
