The Research And Realization Of The Key Technologies In Timber Production Digital Management System Based On J2EE

At present, the lumber management was still the weak link in the forestry work. The problem of the operation behind back in the link of purchase and sale and the lose of lumber in the process of production and so on are still prominent in some enterprises, seriously restricts the enhancement of the enterprise economic efficiency and the market competition, the state property suffers the heavy loss. Therefore, the forestry bureau needs to seek a kind of scientific, digital management imperative. This system has solved the problem mentioned through the omni-directional digitized track management to the entire process of producing, transporting and selling, enhanced the efficiency of operator's working and brought the considerable economic efficiency and the social efficiency for the enterprise.First, the thesis introduces the development background as well as the research content and the significance of the system. Through the careful analysis to the system demand, I decide to use the J2EE frame to develop the system, so as to manage the entire forestry bureau's production management integrally, realizing network and the informational management of the timber production and sale truly.Then, the thesis introduces the designing of the timber production digital management system. I divide the system into several modules such as the system management, the initialization data, the producing and transporting management, the lumber storing management as well as the lumber sale management. Each module integrates organically, links up the entire operation flow in together closely. The system has used three tiers distributional architecture based on the J2EE platform construction, which realizes the separation of operation logic and the demonstration logic. It also allays the emergence of the fat client side as a result of calculating excessively, enhances the operating efficiency of the system enormously.Finally, the thesis introduces the system realization according to the simple and user guiding principle of the system surface. The system has realized storing, demonstration and statistical searching and so on of correlating data in the timber production and sales process. The formidable statistic and searching function of report makes the operator's work greatly convenient, three level of sales management makes the entire sales process to be stricter, and avoiding massive outflows of the state asset greatly.The thesis uses safe protection and management technology, middleware technology, bar code technology, distributed database technology in together, widening the application fields of existing technology. Through the study on key technology, the operational efficiency and security of the system has enhanced greatly. The successful application of the system has far- reaching influence and meaning to the rcscarch and dcvclopmcnt of TaHc forcstry burcau digital forestry and digital TaHe even.
