ASP.Net Services Muzaffargarh

Introduction

We can now use ASP.NET to create Web Services based on industrial standards including XML, SOAP, and WSDL.

A Web Service is a software program that uses XML to exchange information with other software via common internet protocols. In a simple sense, Web Services are a way of interacting with objects over the Internet.

A web service is

• Language Independent.
• Protocol Independent.
• Platform Independent.
• It assumes a stateless service architecture.
• Scalable (e.g. multiplying two numbers together to an entire customer-relationship management system).
• Programmable (encapsulates a task).
• Based on XML (open, text-based standard).
• Self-describing (metadata for access and use).
• Discoverable (search and locate in registries)- ability of applications and developers to search for and locate desired Web services through registries. This is based on UDDI.

Web Service History

• Microsoft coined the term "Web services" in June 2000, when the company introduced Web services as a key component of its .Net initiative, a broad new vision for embracing the Internet in the development, engineering and use of software.
• As others began to investigate Web services, it became clear that the technology could revolutionize (be the next stage in) distributed computing.
• Web services encom a set of related standards that can enable any two computers to communicate and exchange data via a network, such as the Internet.
• The primary standard used in Web services is the Extensible Markup Language (XML) developed by the World Wide Web Consortium (W3C).
• Developers use XML tags to describe individual pieces of data, forming XML documents, which are text-based and can be processed on any platform.
• XML provides the foundation for many core Web services standards (SOAP, WSDL, and UDDI) and vocabularies (XML-based markup for a specific industry or purpose).
• Almost every type of business can benefit from Web services such as expediting software development, integrating applications and databases, and automating transactions with suppliers, partners, and clients.
