Normalized Views

Normalized Views

When the Designer generates a normalized view, it establishes the root element and the multiple-occurring elements that become views in an XML definition.
The following figure shows a DTD file and the elements that become views in a normalized XML definition:
The elements include store, address, product, employee and sales.
Store is the root element. Address, product, employee, and sales are multiple-occurring elements.
The following figure shows a source definition based on the DTD file from the figure above:
The XML definition includes the properties Name, XPath, and Datatype. The Name and XPath properties list the store, address, product, employee, and sales element data. The Datatype property lists the multiple-occurring elements, such as xsd:integer and xsd:string.
The definition has normalized views. The root view is Store. The Address, Product, and Sales views have foreign keys to Store. The Sales view has a foreign key to the Product view.
The following table shows the rows in a data preview for the Store view:
