Um die Leistung von XML als selbstbeschreibende und erweiterbare Sprache zu nutzen, brauchen wir eine Möglichkeit, den zulässigen Inhalt jeder Art von XML Dokument zu definieren und zu beschreiben. Früher wurde dies mit DTDs erreicht, aber diese haben in vielerlei Hinsicht die Anforderungen für die Arbeit mit Daten unterbrochen. XML-Schemas wurden entwickelt, um einen leistungsstärkeren und flexibleren Mechanismus zur Beschreibung der zulässigen Dokumentstrukturen mit XML-Syntax zu bieten. Sie bieten eine Reihe von integrierten Datentypen, die die objektorientierten Mechanismen vieler Sprachen nachahmen, Unterstützung für Namensräume und Einrichtungen für die automatisierte Dokumentation bieten. Professionelle XML Schemas erfassen die W3C XML Schema-Sprache umfassend und lehrt das neue Syntax auf intuitive und logische Weise. Vom Deklarieren von Elementen und Attributen, Erstellen komplexer Inhaltmodelle und Arbeiten mit mehreren Namespaces werden Sie fortfahren, um zu sehen, wie XML-Schemas in realen Situationen verwendet werden. Eine Reihe von praktischen Fallstudien veranschaulicht das Design und die Erstellung von Schemen in den verschiedenen Welten von relationalen Datenbanken, Dokumentenverwaltung und E-Commerce-Anwendungen. Dieses Buch umhüllt: Eine komplette Anleitung zu XML Schema Syntax Using XML Schema Built-in Types, and Leiving New Types.
