Get to know Web Service – In today’s digital era, there are lots of internet users who are increasingly massive and take advantage of technology to support activities such as selling online, online learning, online meetings, entertainment, and so on.

Consultation Via WhatsappWith the high use of applications and websites, it is of course accompanied by a high access burden that is getting heavier. So he created a service to avoid overloading like a web service.
What is a web service and what are its functions? Let’s get to know Web Service and discuss them one by one in the following article.

Explanation of Web Services
Web service is an application that contains various software and databases that can be accessed by a certain intermediary device by means of remote access. The use of this web service has several systems that are constrained by interoperability and integration into several different systems.
By exchanging data using internet-based XML, it allows for contact and interaction between applications.
It’s the same as websites where this web service has a characteristic, namely the use of a URL or uniform resource locator.
But there are several things that make it different, namely the interaction on the web service. The web service URL contains a number of commands, information, and configuration or syntax that builds an application function.
In addition, web services also allow data exchange to be carried out regardless of the form and source of data. This includes database sources and the programming language used. In other words, this web service can be considered as a bridge for the system.
Web Services Function
Web service is a technology with a number of benefits that can be felt directly either by the website or its users. The following are some of the functions of the web service:
Make data accessible
This web service allows a website to be accessed smoothly with a more stable speed. And this technology also functions so that more websites can be opened or accessed anytime and anywhere. This web service is able to minimize various problems related to interoperability and high websites.
Allows access over many protocols
The function of the web service is that it allows access through many protocols. These services can be standardized as well as well defined by the protocol stack. Examples are transportation services, discovery layers, descriptions, XML messages, and so on.
Interaction between systems, formats, and programming languages
The last function of this web service is to create a website so that it can be interacted with even though the operating system, format and programming language are different. Differences in systems, languages and formats used by clients and servers can cause data not to be read correctly. With the existence of a web service all these differences are not a big problem.
Benefits of Using Web Services
Some of the benefits generated from web services include:
Interoperability
Web services can provide services in the form of connections between applications that interact with each other and share data and services. Interoperability also means that a system has different formats and functions to allow interaction without any access restrictions.
Provide Standard Protocols
The benefit of this web service is that it provides a secure standard protocol because the web service has delivery services, XML messages, service descriptions, and service discovery.
That way the advantage is reduced costs due to increased quality and business competition.
Save More with Low Cost Communication
A web service that provides benefits in the form of a SOAP mechanism and its HTTP protocol which can make internet costs much cheaper. And SOAP It can be applied to FTP mechanism.
How Web Services Work
Web service is a system that works in an integrated way. Some of the supported technologies are SOAP, REST, WSDL, and WDDX. In addition, this technology can also use several protocols such as FTP, HTTP, and SMTP.
And by using this technology, the client can send messages in SOAP or REST format. This message contains an XML document that will be transferred across the network via a protocol such as HTTP. Which this message will be delivered to the server. The server will respond and retrieve and display the requested data. As usual, the server will respond and display data in XML, HTML, or JSON formats.
The following is how web services work:
- This client will provide a request message to the server.
- Client messages in XML format, which later this message will be sent to the server via certain protocols such as HTTP. This message will be sent to the web service first.
- The web service will validate the existing request. After checking whether the destination is correct, the web service will later change the message format to a server format that is understood.
- The server will process and respond to the requested message. If the request is in the database then the request will be accepted. Otherwise, the request will be rejected.
- The server will give back the data, which function is to validate and change the message format to a format that the client understands.
- The requested data will be received by the client which can already be displayed in an understandable format.
Types of Web Services
The architecture and technology of web services have several types, including:
Example of Application of Web Services
An example of implementing a web service is the online motorcycle taxi application. Where this web service can be used by ojol services which functions to make it easier for users to order motorcycle taxis online.
The application of this application uses the operating system twice, the first occurs in the application to make a request by inputting the address and destination address.
Then this request will be sent by the user then it will be forwarded and processed on the web service. After processing, this request will be sent by the application user which will continue to the ojol server.
The next step is the gojek server system will receive requests, then calculate travel costs based on mileage. The detailed cost response from the gojek server is sent to users via the web service. Other operating systems occur when the application user clicks Order. The request will be received first to the web service. After being processed on the web service and then sent to the ojol server. After that, Ojol will find the nearest driver based on the user’s location. So after that the gojek server will give a notification that the user has gotten the nearest driver.
SOAP
Simple Object Access Protocol or SOAP is a protocol used as a data exchange process between applications in a structured way using XML. This exchange is carried out using the remote procedure call or RPC method between the client and server. SOAP can also be said as an XML document that can be requested.
Advantages
Language, platform and transport agnostic.
Extensibility and flexibility.
Used to be able to cope with a distributed computer environment.
REST
Representational State Transfer or REST is a system architecture that has been standardized between computer device systems. REST ensures smooth transfer of data between systems. This technology allows interaction or communication to be carried out on systems of different types.
Rest advantages
- Simpler and easier to develop than SOAP.
- More compact and does not require a message exchange layer.
- Easy to learn does not depend on tools.
Weakness rest
- Lack of standards support in terms of security, policy and message reliability.
Certain modes of transport.
WSDL
Web Service Definition Language or WSDL is a type of XML document that is included in the scope of the service description. The main function of WSDL is to describe the contents of a website to clients. This includes an explanation of what methods are available on the web service, complete with their parameters.
WDDX
Web Distributed Data Exchange or WDDX is a web service supporting technology that enables the exchange of data between applications on a web basis. And also WDDX is also used to transfer data between formats.
