关于 ProductModel.CatalogDescription xml 列
以 AdventureWorks2008R2 示例数据库为例进行说明，自行车产品型号的目录说明以 XML 存储在 CatalogDescription 列中。每个产品型号可包含若干单独的产品。例如，自行车产品型号 Road 450 包含若干自行车，如 Road 450 Red 25 和 Road 450 Green 48。同一产品型号的不同自行车的主要区别在于颜色和尺寸。
您可以查询这些产品说明，对其进行 XSL 转换并生成联机目录。存储在 CatalogDescription 列中的目录信息不使用行业标准架构。因此，如果需要，可以编写查询以生成符合行业标准的 XML 产品目录。
这是一个已类型化的 xml 列。可以在此 Microsoft 网站上查看用于此列的架构。此列使用 ProductModelDescription 和 ProductModelWarrAndMain XML 架构。
