5.6.1. Web Services Summary

This tutorial has shown you how to convert an application into a network application.

You have learned how to use XML to send messages between applications.

You also learned how to export a feature from an application (create a web service).

5.6.2. You have learned Web Services, what’s the next step?

Next you should learn WSDL and SOAP.

WSDL

WSDL is a XML-based language used to describe Web services and how to accessthem.

WSDL can describe web service, along with details of the message format and protocol used for web service.

If you want to learn more about WSDL, please visit our WSDL tutorial.

SOAP

SOAP is a simple XML-based protocol that enables applications to exchange information over HTTP.

Or to put it more simply: SOAP is a protocol for accessing 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.
