W3C WSDLActivity
WSDL is an XML-based language used to describe Web Services and how to access them.
WSDL
WSDL (Web Services Description Language) is an XML format used to describe Web Services.

WSDL 1.1
As an XML format that can describe Web Services, WSDL 1.1 was submitted to the W3C as a note in March 2001 (by Ariba, IBM, and Microsoft).
This note also describes how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.
W3C WSDL 1.1 is only a note for discussion (NOTE). The publication of this note does not represent any degree of endorsement by the W3C.
WSDL 1.2
The first Working Draft was published on December 17, 2001.
The latest Working Draft was published on June 11, 2003.
WSDL 2.0
The W3C XML Protocol Working Group is currently working on WSDL 2.0.
Web Architecture
The core of the Web architecture is a Web server, which is generally handled by an independent server. The database server serves as the database server for the information management system. All client data requests are submitted by the Web server to the database server, and then returned to the requesting client by the Web server.
The Web server here can be set up as a gateway, with one end connected to the internal network of the information management system and the other end connected to the enterprise Intranet. This avoids direct exposure of the internal network to the outside while also allowing internal access to the Web site.
