Design And Realization Of Management Information System For Railway Bureau Chunyun

It's more important to raise the construction levels of information of railway and its transportation capability with the rapid development of our economy and more and more request for railway transportation. The management information system of railway Chunyun transportation is an importation composite in construction of information of railway transportation .Railway Chunyun transportation takes on the transportation mission of over burden passengers, however, till now there's no special system to manager the data to share efficiency is relatively low. There out, the key aim this essay tries to realize is how to construct a relatively perfect net system to release the data of Chunyun transportation for railway department to realize resources share ,to make the railway sectors conveniently and quickly carry on the work of querying, searching collecting, reporting forms and loading.Surrounding the whole process of construction of railway Chunyun transportation management system, the establishment of exploitation project, analysis and design of system and the realization of system are detailed discussed and it primarily concludes the following.Firstly systematical configuration of NET framework is particularly introduced and its superiority is expounded, simultaneously ASP.NET as the exploitation technique is defined. After that the accessing technique of ADO.NET databank which is most closely connected to ASP.NET is primarily discussed. The realization of system employs three-levels systematical configurations based on NET level.Secondly the request of system is detailed analyzed and the construction target of system is advanced, jointly the exploitation environment of system being constructed, the technique project for system realization being formulated, and systematical graph of data stream being protracted. Being based upon this the design of framework of system of three-level configuration of B/S system and function of each sub-system and system databank is completed. The key technology in the part of system which is realized is investigated.Based on that the system security is designed and the measurement of system security is detailed discussed from three aspects: user's ciphers protect safe log and databank safety.Finally the task in this essay is summed up and the problem existed in system and next-step construction is expected.
