About the ProductModel.CatalogDescription xml Column
Using Adventure Works for illustration, catalog descriptions for bicycle product models are stored as XML in the CatalogDescription column. Each product model can contain several individual products. For example, Road 450 is a bicycle product model that includes several bicycles such as Road 450 red 25 and Road 450 Green 48. The primary difference among the bicycles in a product model is the color and the size.
You can query these product descriptions, apply XSL transformation to them, and generate online catalogs. The catalog information stored in the CatalogDescription column does not use an industry-standard schema. Therefore, if required, you can write queries to build an industry-standard XML product catalog.
This is a typed xml column. The schemas used for this column can be viewed at this Microsoft Web site. This column uses the AdventureWorks ProductModelDescription and ProductModelWarrAndMain XML schemas.
