About the ProductModel.Instructions xml Column
The Instructions column in the ProductModel table stores manufacturing instructions as XML documents. These documents were created by using Microsoft Word .NET.
Each XML document contains the complete instructions for manufacturing a specific product model. However, each product model can contain several products. For example, Road 450 is a bicycle product model. There are several bicycles in this product model 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.
For example, the HH Mountain frame, LL Mountain Frame, and ML Mountain Frame are specific products with unique product IDs, but are all frame types within the Mountain bike frame product model.
The ProductID column in the Product table identifies each product. The ProductModelID column in the Product identifies the product model to which the product belongs.
The manufacturing process takes a product from one work center to another, and the XML document describes the manufacturing steps at each work center. In describing the manufacturing steps, the tools, materials, blue prints, and diagrams are all wrapped in XML tags. Therefore, you can query the tags. For example, you can use XQuery to find all the tools used in producing a mountain bike.
This is a typed xml column. The schemas used for this column can be viewed at this Microsoft Web site. This column uses the AdventureWorks2008R2 ProductModelManuInstructions XML schema.
