The Global Reconstruction Of Enterprise Information System Based On Aspect Oriented Programming

Since entering in21stcentury, with the rapid development of the domestic economy, alarge number of Chinese enterprises are not limited to the domestic market. Under theguidance of “going global” strategy, domestic enterprises’ pace of globalization is accelerating.With domestic enterprises’ overseas merger and investing in outside borders, the number ofChinese enterprises’ overseas branches is growing rapidly. And the vigorous development ofoverseas business, the amount of domestic enterprises’ overseas assets, business income andemployees are all in the rapid increase. So there are more increasingly frequent and complexinformation exchange between domestic and overseas.Under such circumstances, using semi-artificial or several stand-alone systems tomanage domestic and overseas institutions has been unable to meet the need of enterprises.Therefore, a Global EIS (Enterprise Information System), which is not only for an individualcountry or region, is necessary for domestic transnational enterprises, so that domestic andforeign institutions’ operation and management are united in the EIS. In addition, currentlyenterprises that are developing overseas branches usually have a set of complete and widelyused EIS. Therefore, in the process of globalization transformation of EIS, it is not suitable torebuild a new global EIS, and it is necessary to reconstruct a set of global system on the basisof the existing system and adapting the global business.The globalization transformation of the EIS is in three major aspects:1) The global system users, who are in different countries (regions), need systeminterface and data storage in different languages. Therefore, a global system needs to providemultilingual user interface and to support multi-language I/O, storage and transmission. 2) The countries (regions), where system is deployed, located in different time zoneswith time difference. Therefore, a global system needs to provide the processing ability inmulti time zone, which not only provide users in different time zones with correct timedisplay, but also record reasonable time in multi time zone business. In addition, under theconditions of business in24hours without interruption, system needs to complete thetime-sharing batch processing and report statistics.3) Due to the differences in policy environment and cultural background, leading tosome conventional processes and rules at home, would be contrary to abroad. Therefore, aglobal EIS needs to be able to support a variety of BPM and to ensure that the data structureof the business result is consistent. In addition, a global EIS needs to integrate the originalbusiness process and the business process with local characteristics.However, the reconstruction concerns usually through many functional modules insystem, so if using traditional OOP (Object Oriented Programming), there will be seriousscattering and tangling, which will lead the reconstruction concerns and business logic closelycoupled. So the AOP design pattern is introduced into the reconstruction scheme.AOP (Aspect Oriented Programming) design pattern can separate the common concerns,which are located in the different business modules, and can abstract the horizontalrelationship as an aspect, in order to reduce the coupling degree of concerns to the originalbusiness functions. Through using AOP design pattern, we can make the concern of the EIS’sglobalization as aspects, and realize the original function without the effect of globalizationaspect, which is based on unchanging the EIS’s original function modules.The thesis is aimed to discuss and research the global EIS problems, which are mainlyabout the multi-language, multi time zone, a variety of BPM, and the systems integration. Inaddition, the thesis also provides a solution to reconstructing a global EIS through makingthese common concerns between different function modules as aspects.
