Tommorow evening, Carl & I will be recording Episode #4 of DNRTV:SharePoint 2007. For those who are interested, also checkout DNRTV: SharePoint #1, DNRTV: SharePoint #2, & DNRTV: SharePoint #3. BDC is one of those topics that you just have to leave back the code you used in the demos. So I am chugging out a number of blog posts this weekend describing BDC, and I will be referencing these in DNRTV. So, here goes.

What is BDC?

Microsoft definition: BDC is a new feature in MOSS 2007, it provides you with an easy way to integrate line of business data in MOSS 2007, without any code.
Sahil defintion: BDC is a really cool thing available in the relatively more expensive versions of MOSS. If anything is accessible using an ADO.NET provider, or a web service, that data can be brought into SharePoint, and then you can use it in one of the following ways -

• In-built Webparts
• A simple "Hello World" example
• Extending the "Hello World" example
• Extending the "Hello World" example even further - adding specific finders
• Introducing custom actions on your entities
• Introducing associations between multiple entities
• Lists with Business data type columns
• Search
• User Profiles
• Other custom applications targeting a common runtime object model.
• Making it easier to author XML Applications: BDCMetaMan

In subsequent blogposts, I will cover the above one-by-one, and provide links to the above one by one.
