XML Web Service Introduction
An XML Web Service is a programmable entity. He offers special functional elements. For example: application logic. Use some universal internet standards (XML and HTTP) to access potentially separate systems. The XML Web Service relies widely in an accepted XML and other Internet standards to establish an infrastructure that supports application systems. He solved many problems that have previously hampered this try.
An XML Web Service can not only be used on a separate internal application, but can also be used in many external applications over Internet. Because it is accessed through standard interface, different systems are allowed to work together to a separate web computing.
XML Web Service pursues data and system interoperability, rather than code transplantation. XML Web Service uses XML messages as the basic method of data communication, which can bridge the difference between systems, operating systems, and programming languages of different component modules. Developers can build an app by weaving XML Web Service from different resources. Previously, developers used components to create a distribution application.
One core feature of XML Web Service is that the service is established and used by using an XML message mechanism between the highly abstract existence of execution and extinction of a service. XML Web Service Customers and Services only need to know input, output, and locations.
XML Web Service started a new era in distributed application development. He is not a war of object modules, or is a beautiful competition in programming languages. He has expanded the interoperability of the application when the system and the foundation have the foundation. XML Web Service enhances interoperability to a new level to offset the hostility of opponents. When the next revolutionary development next revolution, XML Web Service will become the infrastructure of all computing device.
