| With the rapid development of Internet technology in recent years,the business needs of Web Services are growing.If it is only through the artificial methods to carry out the design and development,the efficiency will decrease and the fast changing business demands for data service cannot be met.Therefore,how to implement the automatic generation and release for data service by information model,has become the focus of attention in this field.First,this paper defines the representation of the information model.All of the driven model are based on XSD information model,and it is supplemented by association model,inclusion model and database configuration.Then the WSDL interfaces and database tables of data service are automatically generated.These interfaces mainly provide the methods for data storage,search,deletion and modification.Besides the creation and configuration of database tables are through the automated program,which improves the efficiency a lot.After designing the WSDL interface,Java codes can be produced by the existing framework,and they are filled in the corresponding file to implement the data service.Ultimately,this paper integrates all of the automated modules,and accomplishes the user interface configuration and exhibition based on HTML page.The page parameters are mapped to corresponding information model,while the final results are displayed on the page,which includes the user configuration in the initial stage and the client codes download.This paper focuses on the automated generation system architecture,designing and implementing its information model as well as the corresponding interfaces.Finally the Web Services technology combined with model-driven development is achieved,and it can automatically generate all of the database tables,interfaces and data services of Web Services by one-stop based on the information model.The author shortens the software development cycle and improves the efficiency. |
