The Design And Implementation Of Automatic Sales Beverage System Based On WebService

When the Internet technology, especially Web in the20th century, the mid-90s tobecome the mainstream computing, the business model of computing has changeddramatically. The focus of this change is the client and server computing industryconcept that the Web model is composed of a variety of information and theapplication layer consisting of a collection of loosely connected together, and theinformation and applications and resides in a wide range of hardware platform. Tomeet this challenge, Web services have emerged, Web services, portends a newapplication architecture to appear. Web services are self-contained, self-describing,modular applications that can be published, located and invoked, and his function isvery simple (a single request), it can be very complex (a business process.) Webservices message processing is enabled through the use of XML data exchange andapplication logic remote call, so that data can pass through the firewall, and move databetween heterogeneous systems. Although the data and application logic of the remoteaccess is not a new concept, but loose coupling approach to this operation is a newconcept. Web services, Web services between the client and the only assumption isthat the receiver understands the message received. Thus, in any language, using anycomponent model, and run on any operating system programs are able to access Webservices. Once the Web service publish on the web, other applications (or other Webservices) can find and use it.The work of this paper are:(1) Analysis section. Beverage vending machine system needs analysis, analysisof the target system needs to simulate the working principle of vending machines andmethods, design of goods sold, receive money, looking for loose change and otherfunctions. Environment for system development needs analysis to determine thedevelopment environment. (2) System design component. ER diagram for database design, and a detaileddesign, including the system’s use case diagram, class diagram, sequence diagram,state diagrams. Thus simulating the function of the system implementation.(3) The system’s application package. Web Service-based code for system andencapsulation.(4) Test the system. First, the system user interface testing, followed by functionaltesting of the system, including the initialization test, adding beverages, coin test,purchase beverage testing, and test results of a detailed analysis.This article discusses how an existing application functionality packed into WebService, which Web Service-depth understanding of the relevant specifications anddevelopment tools, the main applications of XML, SOAP, WSDL technology, throughthe implementation of AXIS studied philosophy, summed up number of related designpatterns, and to achieve the following objectives:(1) study and summarizes the thinking of Web services architecture, Web Servicerelated technologies.(2) design and implementation of an automatic beverage marketing system.(3) A view of the Web Service AXIS application package.(4) the Web Service-based sales system of automatic beverage package.(5) completed the sale of automatic beverage system testing.(6) proposed a system design deficiencies and proposed specific amendments.The implementation of the entire system using advanced technology, made ascientific design, to achieve a relatively high overall performance, the furtherdevelopment of Web services, work to lay a solid foundation. We believe that Webservices technology with the continuous development and improvement of the systemarchitecture will reveal a new era of e-commerce page.
