What are web services? It may sound a bit foreign to all of you. Do any of you already know, but still little? If so, let’s see the explanation below.
Definition
Web service is an application that contains a collection of databases and software or parts of software programs that are accessed remotely by devices with certain intermediaries. Through web services, it allows users to overcome problems in the form of interoperability and integrate different systems. In general, web services have a special feature in the form of a URL like a web. What makes the difference is the interaction provided by the web service itself. URLs in web services only contain a set of information, commands, and configurations (syntax that is useful for building certain functions of the application).
Web services are able to exchange data regardless of the source of the database, the language used, and on what platform the data is consumed. It is this capability that allows web services to become a bridge for various systems.
Benefit :
Interoperability
Web services provide services in the form of connections between applications to talk, and share data and services. Other applications can use web services, such as VB or .NET which can talk to Java web services and vice versa. This system is commonly used to create a platform independent application and technology.
Standard Protocol
Web service is a web service that has industry and communication standards. Transport services, XML messages, Service Descriptions, and Service Discovery Layer have used the protocols well defined by the web service protocol stack. Standardization of the stack protocol itself provides benefits such as reduced costs due to competition and improving the quality of a business.
Low Cost Communication
Web services that use the SOAP mechanism on the HTTP protocol, will have the effect of using cheap internet. Apart from SOAP, web services can also be applied to reliable transport mechanisms such as FTP.
Showing Functions on Network
Web services allow managed code units to be used remotely in HTTP calls. The system can be activated by making a request via HTTP. Web services also allow users to expose existing code over a network.
