Study And Application Of COM+ On Iron & Steel Enterprise Marketing Information System

With the rapid development of computer and network technique, the complexity of the computer software is also increasing, and the application system based on the traditional 2-tier Client/Server architecture can't meet the need of the users and their business now. So a kind of distributed 3-tier Client/Server mode comes up. With the appearance of Component Object Mode, it is possible to realize the multi-tier application system, which can easily handle the problems appeared in the 2-tier architecture, such as poor maintainability and security, high cost, weak retractility and so on.First of all, the thesis analyzes the idea of developing the software system with the component technique and the superiority of this technology, compares the COM+, CORBA and EJB techniques and studies the COM+ in detail, including the basic structure, system structure and system service. Secondly, the thesis discusses the application feasibility of the COM+ technique based on COM in the iron & steel enterprise marketing information system. At last, the author puts forward a solution of distributed 3-tier Client/Server mode based on COM+.In term of the techniques and theories above-mentioned, this thesis accomplishes the model in the project- Integrated Marketing Information Network Management System for Liuzhou Iron & Steel Com, based on the original system. And primarily realizes the 3-tier Client/Server System, which can improve the performance of the Marketing Information Network Management System in the research by using the technologies such as C++, COM+, etc.
