Asp.net+xml Web service clients Create Web services

An XML Web service is a programmable entity that provides a particular functional element, such as application logic, and can access many potentially disparate systems using ubiquitous Internet standards such as XML and HTTP. XML Web services, which rely on widespread acceptance of XML and other Internet standards, use them to create an infrastructure that supports application interoperability, addressing many of the problems that have hindered interoperability in the past.

XML Web services can be used in a single application, or the Internet is used by many applications. Because an XML Web service can be accessed through a standard interface, it allows multiple different systems to collaborate on a single network computation.

XML Web Services do not pursue the ability to migrate code, but rather provide a viable solution to enhance interoperability of data and systems. XML Web services use xml-based messages as a basic data communication method, bridging the bridge between systems that use different component models, operating systems, and programming languages. Developers can use the same approach as creating a distributed application using components to create applications that assemble XML Web services from different sources.

One of the core features of XML Web Services is the high level of abstraction that exists between implementing and using services. By using xml-based messages as a mechanism for creating and accessing services, both the XML Web service client and the XML Web service provider do not need to know anything about each other except inputs, outputs, and addresses.

XML Web Services can usher in a new era of distributed application development. There is no longer a contest between object models or a pageant of programming languages. This is done at the expense of application interoperability when the system is tightly coupled with proprietary infrastructure. XML Web services provide interoperability at a new level, completely denying the competition between those counterproductive systems. As the next revolutionary advance of the Internet, XML Web services will become the basic structure of connecting all computers.
Simple Service

The most basic solution to the implementation of the XML Web service is to provide some basic functional modules for the customer to use. For example, an E-commerce application is challenged by the need to calculate charges for different freight modes. Such applications need to obtain the current shipping cost form from each shipping company in these calculations.

Applications can use standard transport protocols such as HTTP to send a simple xml-based message over the Internet to an XML Web service that calculates freight costs. This message may provide the weight and size of the package, the point of delivery and receipt, as well as other parameters such as service levels. The shipper's XML Web service then uses the latest price list to calculate the freight cost, and uses a simple xml-based response message to return this number to the calling application to calculate the customer's overall cost.

Application integration

You can use XML Web services to integrate an existing application that looks completely different on the surface in an integrated fashion. Most companies have customized software for each department, producing a series of useful but isolated data islands and business logic. Because of the changes in each application environment and the evolving nature of technology, it is very important to create a feature set from these applications.

With XML Web services, it is possible to expose data and functionality from existing applications as an XML Web service. You can then create an integrated application that uses the collection of these XML Web services to enhance interoperability between the components of your application.

Work Process Solutions

XML Web Services can provide a very powerful mechanism for applications to create End-to-end workflow solutions. Such a solution is suitable for long running scenarios such as business to business transactions.

The BizTalk Framework provides an additional protocol layer that defines the mechanisms for identifying and distributing messages, defines their lifecycle, encapsulates them (usually with attachments), delivers them securely to their destinations, and ensures the security of authentication, integrity, and confidential content.

Microsoft BizTalk Server provides the infrastructure and tools to route, transform, and record infrastructure for rule-based business documents. This infrastructure enables companies to consolidate, manage, and automate business processes by exchanging business documents, such as purchase orders and invoices, within their internal or other institutions.

BizTalk Orchestration is a technology that is contained in a BizTalk Server that defines the state of a single XML Web service and as a component of an XML Web service that constructs multipart business processes.
