WSDL is a XML-based language used to describe Web Services and how to accessWeb Services.

4.14.1. WSDL

WSDL (Web Services Description Language) is a XML format used to describe Web Services.

To learn more about WSDL, please read our WSDL tutorial.

WSDL 1.1

As an XML format that can describe Web Services, WSDL 1.1 was recommended tothe W3C (by Ariba, IBM, and Microsoft) in a record in March 2001.

This record also describes how to use WSDL in combination with SOAP 1.1, HTTP GET/POST, and MIME.

W3C WSDL 1.1 is only a NOTE for discussion. The release of this record does not represent any degree of W3C approval.

WSDL 1.2

The first working draft was issued on December 17, 2001.

The latest working draft was released on June 11, 2003.

WSDL 2.0

The W3C XML Protocol working Group is currently working on WSDL 2.0.

4.14.2. WEB structure

The core of the Web structure is a Web server, which is generally undertakenby an independent server. The database server is the database server of theinformation management system. Each client data request is submitted by theWeb server to the database server, and then the Web server returns the client that sends the request.

The Web server here can be set as a gateway, one terminal is connected to the intranet of the information management system, and the other end is connected to the enterprise Intranet, which not only avoids the intranet being directly exposed to the outside, but also enables the internal to access the Web site.

《地理信息系统原理、技术与方法》  97

最近几年来，地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持，如城市管理、区划、环境整治等等，地理信息成为信息时代重要的组成部分之一； “数字地球”概念的提出，更进一步推动了作为其技术支撑的GIS的发展。 与此同时，一些学者致力于相关的理论研究，如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面，并且这两个方面构成了相互促进的发展过程。
