Web services allow several applications written in many programming languages to connect with each other. Find out everything you need to know about it. Including advantages, definition and importance Latest web applications are developed in different programming languages: Java, Net, Angular JS, and Node.js. In fact, it can be difficult to confirm connect between these applications. This is the reason why we use web services. There are many companies which provide digital marketing services for your business. They also deliver best web services which is very useful for your business. Web services: What is it? Web services deliver a common platform for several applications developed with different programming languages to connect with each other. A web service is a standardized medium allowing communication between client and server applications on the World Wide Web. It is a software module designed to perform several tasks. Web services: how does it work? Once raised, a web service is able to provide its functionalities to the client who appeals it. The client invokes a series of web service calls through requests sent to the server that hosts the service. These requests are made through Remote Procedure Calls. For example, Amazon offers a web service that delivers prices for products sold online through Amazon.com. The front end or the presentation layer can be in .NET or in Java, but these two programming languages will have the capacity to connect with the Web Service. The main module of a web service is the data transferred between the client and the server. These data are in XML. XML is the counterpart of HTML. Simply put, it can be defined as an intermediate language understood by most programming languages. Thus, the applications communicate with each other in XML. To send XML data between applications, web services use SOAP (Simple Object Access Protocol). The data sent from the web service to the application are called SOAP messages. It is simply a document in XML format. Web services: what are the Advantages? In start to allowing applications written in several programming languages to communicate with each other, web services deliver other advantages. First of all, they allow access to features via the internet. Indeed, the functionalities delivered by the web service to a client application are invoked via the HTTP protocol. They can therefore be invoked via the internet. At a time when all applications are connected to the Internet, web services have therefore become much more useful than in the past. In addition, web services allow interoperability between applications. They allow various applications to communicate with each other, and to share data and services. Thus, rather than having to write specific code that can be understood only by specific Applications, it is possible to write generic code that can be understood by all applications. Another advantage of web services is that they use a standardized industrial protocol for communication. The four layers including Service Transport, XML Messaging, Service Description and Service Discovery use well-defined protocols. Finally, web services make it possible to reduce communication costs. Knowing that they use SOAP via the HTTP protocol, it is possible to use a low-cost internet connection to implement the web services.
