XML Schema Summary

This tutorial has shown you how to describe the structure of an XML document.

You have learned how to use XML Schema to define legal elements of an XML document, just like DTD. We believe that XML Schema, as a replacement for DTD, will soon be used in most Web applications.

You have also learned that XML Schema is perfect. Unlike DTD, XML Schema supports data types (data type) and namespaces (namespace).

Please refer to our XML Schema 参考手册 For more information about XML Schema

Now that you have learned XML Schema, what will you learn next?

The next step is to learn WSDL.

WSDL is a schema-based language that describes Web service and how to access them.

WSDL can describe Web service, along with the message format and protocol details for Web service.

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
