| The component technology is a rapid-developing technology recently. With the continuous development of the Internet technology and the wide spread of network connection and more higher speed of network, the web database technology in Internet is becoming the hot point of recent database application. The combination of them makes the component-based web database application. It has extremely expanded the range of database system. In this thesis the development of the ZMCC Intergrated Maintenance Electronic Platform System is based on a combination of the above results.First, thesis gives a brief introduction to the component-based application mode in Internet and points out this mode is the useful method of solving many application problems. Then thesis analyses and compares three typical component model.Furthermore, thesis discusses the system structure of database, introduces the working and characteristic of terminal/mainframe, client/server, browser/server model, and summarize their advantages and disadvantages. Browser/server is better than client/server, and it doesn't depend on operating system and hardware, and client on browser/server model isn't too "fat". Browser/server is the widespread used model at present.At last, combined with development practice of the author as a project manager in ZMCC Intergrated Maintenance Electronic Platform System, the thesis introduces the system selection, system design and architecture choices. J2EE is chosen as development platform and introduced its system structure. Thesis analyses four system structures for designing the whole system from different perspectives, including the interface design and realization of the system . Finally, thesis discusses the implementation method , requirement analysis and points out the issues needed pay attention to as a project manager for project development and implementation process, and follow-up prospects. |
