Description
XML Schema is an incredibly powerful - and complex - document
schema language with capabilities such as strong typing, modularity,
inheritance, and identity constraints. The World Wide Web consortium
to replace XML's DTDs as a specification has defined the XML Schema
language.
To leverage the full power of XML, companies need shared vocabularies
to base their documents & scripts upon. XML Schema makes it
possible to create those shared vocabularies.
From declaring elements, attributes and complex content models
to working with multiple namespace the student will see how XML
schemas can mimic object-oriented features of many languages.
Practical examples will illustrate how the design and creation
of schemas work in the world of relational databases, e-commerce
applications and document management.
