Design and implementation of a data provider server using web service technology for mobile application

---

Recently demand of the latest data has been a significant issue as the importance of stock price changes in this modeled system. To provide real-time quote and book information for securities traded, an information provider is required.rnrnMain objective of this research is to create an application based on web service to provide and manage data. The service provider retrieves actual data of stocks at each certain period of time, manage them into database system, and expose the invocation method on the web to provide data as requested by client.rnrnA design of system architecture that support distributed system concept is made to achieve the objectives. Designed system architecture provides ability to retrieve and update data from several data sources which publish the data in different forms. To fulfill this requirement, a data grabber using PHP and a Windows Service which execute the grabber each five minutes is created. In order to make data retrieval time not exceeds service's timer, multithreaded service is used. Methods created reside and encapsulated in COM+ component, while the interfaces are exposed in Web Service. Since the data are exchanged in XML format, they can be invoked through HTMTP protocols and thus, provide interoperability.rnrnBased on the result of the research web service technology can be implemented to provide real time data for clients running on any platform, especially mobile devices.
