Web service is a standardized medium to propagate communication between
the client and server applications on the World Wide Web. A web service is a
software module that is designed to perform a certain set of tasks.The web
services can be searched for over the network and can also be invoked
accordingly.
How to work web
service:
These requests are made through what
is known as remote procedure calls. Remote Procedure Calls(RPC) are calls made
to methods which are hosted by the relevant web service.
The main component of a web service is
the data which is transferred between the client and the server, and that is
XML. XML (Extensible markup language) is a counterpart to HTML and easy to
understand the intermediate language that is understood by many programming
languages.
So when applications talk to each
other, they actually talk in XML. This provides a common platform for
application developed in various programming languages to talk to each other.
Web services use something known as
SOAP (Simple Object Access Protocol) for sending the XML data between
applications. The data is sent over normal HTTP. The data which is sent from
the web service to the application is called a SOAP message. The SOAP message
is nothing but an XML document. Since the document is written in XML, the
client application calling the web service can be written in any programming
language.
Why do you need
a Web Service?
Modern day business applications use
variety of programming platforms to develop web-based applications. Some
applications may be developed in Java, others in .Net, while some other in
Angular JS, Node.js, etc.
Most often than not, these
heterogeneous applications need some sort of communication to happen between
them. Since they are built using different development languages, it becomes
really difficult to ensure accurate communication between applications. Web
services provide a common platform that allows multiple applications built on
various programming languages to have the ability to communicate with each
other.
Type of Web
Service
There are
mainly two types of web services.
-
SOAP
web services.
-
RESTful
web services.
In order for a web service to be fully
functional, there are certain components that need to be in place. These
components need to be present irrespective of whatever development language is
used for programming the web service.
Advantages of
web services
We already understand why web services
have emerged in the first place, which is to provide a platform that can allow
different applications to talk to each other. But let's look at some other
benefits of why using web services is important.

Uses of Script:
Script scripts are used to automate
and execute operations on a computer. The scripts have made the Internet
environment much usable, comfortable and more flexible. Each Script represents
texts that contain a list of instructions that are executed by a program or a
specific programming language in order to achieve the desired action. Thus,
users will be prevented from taking many steps to reach certain results while
browsing a website or working on computers. A script is the nature of text that
allows it to be opened and edited by text editors, i.e. it is open source
