What is Webservice??

Web服务是独立的，模块化的，分布式的动态应用程序，可以通过网络进行描述，发布，定位或调用以创建产品，流程和供应链。这些应用程序可以是本地，分布式或基于Web的。 Web服务建立在TCP / IP，HTTP，Java，HTML和XML等开放标准之上。



Web服务是通过其进行通信的客户端和服务器应用程序万维网（WWW）超文本传输​​协议（HTTP）。如万维网联盟（W3C）所述，Web服务提供了在各种平台和框架上运行的软件应用程序之间进行互操作的标准方法。由于使用了XML，Web服务的特点是具有良好的互操作性和可扩展性，以及它们的机器可处理描述。 Web服务可以以松散耦合的方式组合以实现复杂的操作。提供简单服务的程序可以相互交互，以提供复杂的增值服务。

Web Services are self-contained, modular, distributed, dynamic applications that can be described, published, located, or invoked over the network to create products, processes, and supply chains. These applications can be local, distributed, or Web-based. Web services are built on top of open standards such as TCP/IP, HTTP, Java, HTML, and XML.

Web services are client and server applications that communicate over the World Wide Web’s (WWW) HyperText Transfer Protocol (HTTP). As described by the World Wide Web Consortium (W3C), web services provide a standard means of interoperating between software applications running on a variety of platforms and frameworks. Web services are characterized by their great interoperability and extensibility, as well as their machine-processable descriptions, thanks to the use of XML. Web services can be combined in a loosely coupled way to achieve complex operations. Programs providing simple services can interact with each other to deliver sophisticated added-value services.

Why we use Webservice??

Web服务的主要优点包括：



跨越多种硬件和软件平台的分布式应用程序之间的互操作性



使用Web协议通过防火墙轻松，广泛地访问应用程序



一种跨平台的跨语言数据模型（XML），有助于开发异构分布式应用程序


由于您使用标准Web协议（如XML和HTTP）访问Web服务，因此Web上的各种异构应用程序（通常已经了解XML和HTTP）可以自动访问Web服务并且彼此沟通。



这些不同的系统可以是Microsoft SOAP ToolKit客户端，Java平台，企业版（Java EE）版本5应用程序，遗留应用程序等。它们是用Java，C ++，Perl和其他编程语言编写的。应用程序互操作性是Web服务的目标，取决于服务提供商是否遵守已发布的行业标准。

如何在Asp-Net中创建网络服务 [ ^ ]

Major benefits of Web services include:

Interoperability among distributed applications that span diverse hardware and software platforms

Easy, widespread access to applications through firewalls using Web protocols

A cross-platform, cross-language data model (XML) that facilitates developing heterogeneous distributed applications

Because you access Web services using standard Web protocols such as XML and HTTP, the diverse and heterogeneous applications on the Web (which typically already understand XML and HTTP) can automatically access Web services and communicate with each other.

These different systems can be Microsoft SOAP ToolKit clients, Java Platform, Enterprise Edition (Java EE) Version 5 applications, legacy applications, and so on. They are written in Java, C++, Perl, and other programming languages. Application interoperability is the goal of Web services and depends upon the service provider's adherence to published industry standards.
