Web Service Definition and when it is use and not to use


What is web service and its use.

Web services 
The Definition Web Service A web service is any part of software that makes available over the network and uses a XML (Full form of XML is Extensible Markup Language (XML) is a markup language in a format which is both human-readable and machine-readable.) format messaging system. XML is used to encode all communications to a web service. Any application which has permission to access service can use service from anywhere. It is platform independent. 

(sometimes called application services) are services (usually including some combination of programming and data, but possibly including human resources as well) that are made available from a business's Web server for Web users or other Web-connected programs. Providers of Web services are generally known as application service providers.

It is based information send-Receive systems that use the by Internet for application (software)-to-application (software) communication. This application can include objects, messages, or documents.

Use Of Web Service

It is system software. Specially design for support machine-to-machine interaction over a local network internet. The basic services supported platform is XML and HTTP or HTTPS. XML can be used between different platforms and programming languages and complex messages and functions. It is help to solve interchangeability by giving your applications a way to integrate their data. For Example your one website is online and you also want to make its android application. That time you need web service so you’re both application work synchronously. You require this because user sometime work on website and some time also use mobile application like android app then user want synchronized own data. For that developer use same service for both platform website application and android application so no need to work for both platforms. 

When Not Use Web Service

when your application no need to synchronize and when more application use only single service because of that more load on server.mostly when service use for operation on database that time overload problem occurs so when number of application use web service which is ping db its problematic to database overhead.

so for database you need to make multiple version of web service so its useful to maintain database overhead.
