Stomach cancer is staged according to where the cancers found and how far it has invaded the stomach tissue, or if it has spread beyond the stomach and into other organs (stages 0 to IV). The treatment of stomach cancer depends on the size and location of the tumor, the stage of the disease and the patient's general health.
The star schema gets its name from the physical model's resemblance to a star shape with a fact table at its center and the dimension tables surrounding it representing the star's points.
Schematron. An XML schema that is used to validate an XML document. Unlike grammar-based schema languages, Schematron is made up of XPath patterns that define the tree structures and relationships. It can be used by itself or embedded within a W3C XML Schema or RELAX NG schema. The final draft of an ISO version of Schematron was made available in late 2004 and was published as an ISO standard in 2006. For more information, visit www.schematron.com. See XML schema.
