The Research Of Improving Exploit Efficiency Of The E-Government Affair Software In Different Security Levels.

In the base of the analysis and investigations of the exploiture efficiency of traditional E-Government affair softwares, this paper has put forward a new rights control method which based on models. It also deeply studied how to use this method to abstracting and modelling the internal control points of a function; how to erect the data accessing control rules; how to explain the general function control model and data accessing control rules in softwares.The purpose of the researchment is: In different security levels, improve the exploiture efficiency of E-Government affair softwares; make the softwares more flexible; reduce the exploiture and maintenance cost of the softwares. In order to improve the work efficiency of the government and save cost.First, the paper made an introduction of the current status of the E-Government affair softwares' exploiture and has pointed out its problems. The problem is, current E-Government affair softwares in different security levels, can't satisfy the user's "temporal and dimentional individuations". The user's requirement on security controls of subfunctions in a single function has beem moved from a whole function to the subfuntions in it; further more, as the requirement of E-Government affair softwares changes with time, it can't satisfy quick response requirement of the user. It makes the efficiency, the cost, the access control in different security levels become serious problems on the road of the development of the E-Government affair softwares. Then, the paper analysised the problem before, made some key technical questions. In order to solve the key technical questions, the author put forward a new rights control method based on classical models. It has added a new subfuntion model to the original function model which makes the control level to the internal of the function and the softwares more flexible in the basis of user's request. Next, in order to prove the new method, the author has designed a salary management software with VB6.0 using two methods, one is traditional, the other is model-based, and has compared their functions and exploiture efficiency. After the comparation, it has made a conclusion that the model-based method is more efficient than the traditional method. It can solve the problems like high cost, low efficiency, less flexible etc, and it also can satisfy the user's requests in different security levels. At last, the author reviewed the whole procession of the researchment, made a prospection to the researchment a few decades later.Through the researchment, the paper has put forward a new rights control method which based on models. It can support rights control in lower levels, improve the exploiture efficiency of the E-Government affair softwares, make the softwares more flexible, reduce the cost of the softwares, and satify the user's requests better. More developed, the method can be used in designing the E-Government affair softwares, make more profit to the users and the software corporations. It can be used widely.
