Web Services To Synchronize Data Between Website And Mobile Application

Nowadays people want to have access to any information they need instantly, anywhere and anytime. Portable devices such as cell phone, tablet and laptop, can answer modern people needs of information. Why? Because the development of technology is very rapidly. Every month we can see numerous newfound systems or tools that help people doing their activities. This change also happens to the internet world.One way to find information using a portable device is through its browser, but it takes longer time since this browser has to load the whole content of the accessed web. Using mobile application of the relevant web application is another way to access information. It makes a lot of web developer dives into the mobile applications industry. Mobile applications usually serve as the front-end of a web application. To solve this problem, we can implement a technology, called Web Services.Web Services is client and server applications that communicate over the World Wide Web’s (WWW) Hyper Text Transfer Protocol (HTTP). Web Services provides a standard means of interoperating between software applications running on a variety of platforms and frameworks. A web services is any service that is available over the internet, and is not tied to any operating system or programming language. Briefly, web service has three important parts which are the service provider, service requestor and service registry.For this research, I build a simple blog application by Ruby on Rails and Objective-C programming language. To prove that whether the JSON Web Services can run properly or not, I did testing and experiments to both applications. The testing applies black box method and refers to existing sequence diagram, and is done to every features of both applications. While the experiment I did is to add a new data to web application, then make sure such data can appear in the mobile application, and vice-versa. The result of the testing and the experiments are that JSON Web Services can run properly. Data transaction between web application and mobile application is done smoothly and JSON file is well functioned although web application and mobile application are developed in different programming language.
