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.
In markup languages, Schematron is a rule-based validation language for making assertions about the presence or absence of patterns in XML trees. It is a structural schema language expressed in XML using a small number of elements and XPath. In a typical implementation, the Schematron schema XML is processed into normal XSLT code for deployment anywhere that XSLT can be used. Schematron is capable of expressing constraints in ways that other XML schema languages like XML Schema and DTD cannot. For example, it can require that the content of an element be controlled by one of its siblings.
