Application Information
You are a database administrator for a manufacturing company. You have an application that stores product data. The data will be converted to technical diagrams for the manufacturing process.
The product details are stored in XML format. Each XML must contain only one product that has a root element named Product. A schema named Production.ProductSchema has been created for the products xml.
