Web Services-The Real Deal
Web Services-The Real Deal
The rapidly increasing number of vendors surely gives you an idea of the wonders Web Services are offering through technologies like WSDL, XML, SOAP, and many more. Web services are among the crucial features the companies need to concentrate on while looking to purchase any new business. This is quite beneficial for growing companies.
Also termed as W3C, it is a software system, designed for supporting the interoperable interaction among the machines over any network. Developed in a single language, and can also be used with multiple languages for increasing the connectivity among the applications. When communication gets established between two systems, the software that has requested for the service is known as service requester, and the opposite system is known as the service provider.
How does communication take place in Web Services?
Thinking how does communication take place in the process of web services? Here is the process of communication carried out for Web Services.
The communication between the systems is carried out; there are specific rules that need to be looked after. The rules include the process of requesting data, the parameters needed in the request, the structure of the produced data, along with the error messages too, which are displayed when the rules are broken. The rules well defined in a particular file termed as WSDL given the extension .wsdl.
When a web service is designed, a file gets generated with the extension .wsdl. for describing the web services using the protocol of SOAP for publishing and even registering the service with UDDI. This also helps in availing the service to other users. The UDDI helps in determining the particular software system which should be contacted for that data type.
After that, the service requester would contact the UDDI and look for any provider who serves with the data required. After that, the communication takes place with the service provider who is working with the SOAP protocol. The service provider further validates the communication request through WSDL and returns back the data structured in XML designed with the SOAP protocol. The XML data is again verified with XSD.
Hence, in this way, the entire process of communication takes place for obtaining web services.
What are the benefits of Web Services?
Here are some of the basic benefits of using Web Services that would attract you towards working with it.
Revealing the Existing Functions
The Web services basically are managed through a code which is invoked through HTTP. And this is easy to activate with the help of HTTP requests. The services help you in exposing functionalities of the user’s existing code. Once it is exposed to the network, other applications can use it for various functions.
The web services are using the standardized protocols at the time of communication. Be it XML, Service Transport, Service Discovery, or even Service Description, the protocols used are well defined in the protocol stack. The standardized protocols would provide businesses with benefits like reduced cost, increased choices, and increased quality.
The web services that have opted for SOAP instead of HTTP protocol, it becomes easy for the user to work with the low-cost internet plans that are existing. This solution reduces the cost compared to other proprietary solutions. Again, this can also be used on other transport mechanisms that are reliable.
The web services provider with a number of options for communicating and sharing the services and data. There are many other apps that are working on the basis of web services. The services are used for making the technology and application platform-independent.
Web services have proved to be the silent backbones to modern technology. The common communication standards, interfaces, and even protocols, that have progressed in the past few years also allow the users in developing tablet, PC or mobile-based applications capable of ordering lunch, finding gifts rapidly, stock return prices, etc.
