Round System Analysis Model Based On The Cost Of Database Applications

With the development of science and technology, each course tends to become more thorough and deeper in its field. These courses with performance, structure and principle as their goal of research dominates, according to the research into all courses. In the light of the research projects and documents home and abroad, most researches focus mainly on the positive study of the design of application system, the formulation of standards and correlation between courses in respective field, while few focus on negative study according to defective and cost, let alone the systematical negative study.Even so, it is clear that when designing analysis objects, in order to thoroughly analyze and understand them, we should study in both positive and negative ways. If we can analyze the results based on both ways and make use of the advantages and skip over the disadvantages of them, we will have the hope of finding out the best solutions to designing the objects.①By this means, the thesis will offer a 360°view of complete analysis system about designing the objects and systematically set up a model of cost analysis based on idea of negative study.②This model level-dividedly and classifiedly studies these objects from the angle of processing prerequisites, system structure and function, system designing strategy, system accomplishment and test, further system development in the system designing objects. At the same time, it classifies and compiles the original cost, alternative cost and potential cost.③Through this model, the author will analyze the cost of an application system of an education management statistics working under Windows 2000 and SQL2000 and appraise the cost of the processing atmosphere, system structure and function, strategy of system designing, system accomplishment and test, further system development in this set of statistics. By analyzing them, we are to analyze various costs about the negative elements in the application system of the statistics, which can help the designer further understand the designing element of the objects, hence design the application objects more effectively, attain to the best way of designing, improve the working efficiency, and decrease the rate of making mistakes in the process of designing. Negative analysis is, undoubtedly, a motivator of developing different courses.
