Integrating Line Of Business Data

In SharePoint you can easily integrate line of business (LOB) data into SharePoint for easy collaboration and searching. To integrate this data you will be using the Business Data Catalog. The official Microsoft documentation says that BDC allows for the integration of line of business without using code. Although this is mostly true, you will need a good understanding of XML to create the BDC definition. Note that BDC is only available in MOSS, not WSS. Once you have the BDC set up you can use the data in web parts, lists, search, and user profiles. The following site has some good examples of using the BDC, creating the definition, and tools to aid in the creation of the definition files. Believe me, you don't want to build the BDC definition from hand.
