Research And Implementation Of Simplifying Data Programming Based On Service Data Object

With the rapid development of IT industry and the growing demand for basicbusiness of enterprises, at present, the complexity of accessing to data is growing dayafar day. In recent years, however, with the bringing forward Service OrientedArchitecture (SOA) of software architecture, Service Data Objects, which is a basicspecification of SOA, simplifies greatly data programming. It plays an important rolesin decreasing the complexity of accessing data. So if we can apply SDO to Strutsframework applied widely, software developers will be certain to be liberated fromtechnical details of accessing the given background data. That will increase their workefficiency and make them be involved in business logic.This paper mainly researched the problem of simplifying data program. First, theauthor described the background and status of the study of the subject, and pointed outthe purpose and significance of the study. And then, on the base of introducing SDOsoftware framework and Struts software framework in details, this paper deeplyanalyzed SDO software framework and SDO specification and raised an application ofStruts framework with the extension of SDO framework to simplify data programming.And then, as the key, this paper studied the basic realization of the Struts frameworkextension mode based on SDO framework, and focused on one of the key ways–autoupdating data access layer. Finally, through the example of a purchase order onlineapplication system, this paper validated the function of auto updating data access layer,expatiated on the implementing process based on simplifying data programming andrealized one of the main components using the platform of Eclipse+Jboss in Windows.This is research and implementation of simplifying data programming based on servicedata object.
