The Student Information Management Systemis an information management one kind within system, currently information technique continuously of development, the network technique has alrea

5、student result management the system had in the school very big function, all can be more convenient, fast for the student and the teacher coming saying and understand accurately with management everyone noodles information. AbstractIt is a very heavy and baldness job of managing a bulky database by
6、 manpower. The disadvantage, such as great capacity of work, low efficiency and long period, exist in data inputting, demanding and modification. So the computer management system will bring us a quite change.Because there are so many students in the school, the data of students information is huge,
7、 it makes the management of the information become a complicated and tedious work. This system aims at the school, passing by practically of demand analysis, adopt mighty VB6.0 to develop the student information management system. The whole system design process follow the principle of simple operat

The student information management system including the function of system management, basic information management, study management, prize and punishment management , print statement and so on. Through the proof of using, the student inform

The thesis introduced the background of development, the functions demanded and the process of design. The thesis mainly explained the point of the system design, the t

The student managed the creation of the system to reduce the inconvenience on the manpower consumedly, let the whole student the data management is more science reasonable.The place that this system has most the special features is the bac

16、 question. More and more are also urgent along with school automationthe marks management when science and technology rapid development,therefore is essential to develop the software system of marks register to assist the school teaching management.So that can improve the marks management,enhance th

Any given computer application involves at least three components: hardware, software, and data. Merely writin
18、g a program isnt enough, because the program is but one component is in a system.A system is a group of components that work together to accomplish an objective. For example, consider a payroll system. Its objective is paying employees. What components are involved? Each day, employees record their
19、hours worked on time cards. At the end of each week, the time cards are collected and delivered to the computer center, where they are read into a payroll program. As it runs, the program accesses data files. Finally, the paychecks are printed and distributed. For the system to work, people, procedu
20、res, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system.Systems AnalysisComputer-based systems are developed because people need information. Those people, called users, generally know what is required, but may
21、lack the expertise to obtain it. Technical professionals, such as programmers, have the expertise, but may lack training in the users field. To complicate matters, users and programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professional wh
22、o translates user needs into technical terms, thus serving as a bridge between users and technical professionals.Like an engineer or an architect, a systems analyst solves problems by combining solid technical skills with insight, imagination, and a touch of art. Generally, the analyst follows a wel
23、l-defined, methodical process that includes at least the following steps:Problem definitionAnalysisDesignImplementationMaintenanceAt the end of each step, results are documented and shared with both the user and the programmers. The idea is to catch and correct errors and misunderstandings as early
24、as possible. Perhaps the best way to illustrate the process is through example.Picture a small clothing store that purchases merchandise at wholesale, displays this stock, and sells it to customers at retail. On the one hand, too much: stock represents an unnecessary expense. On the other hand, a po
25、or selection discourages shoppers. Ideally, a balance can be achieved: enough, but not too much.Complicating matters is the fact that inventory is constantly changing, with customer purchases depleting stock, and returns and reorders adding to it. The owner would like to track inventory levels and r
26、eorder any given item just before the store runs out. For a single item, the task is easy-just count the stock-on-hand. Unfortunately, the store has hundreds of different items, and keeping track of each one is impractical. Perhaps a computer might help.Problem DefinitionThe first step in the system
27、s analysis and design process is problem definition. The analysts objective is determining what the user needs. Note that, as the process begins, the user possesses the critical information, and the analyst must listen and learn. Few users are technical experts. Most see the computer as a “magic box
28、,” and are not concerned with how it works. At this stage, the analyst has no business even thinking about programs, files, and computer hardware, but must communicate with the user on his or her own terms.The idea is to ensure that both the user and the analyst are thinking about the same thing. Th
29、us, a clear, written statement expressing the analysts understanding of the problem is essential. The user should review and correct this written statement. The time to catch misunderstandings and oversights is now, before time, money, and effort are wasted.Often, following a preliminary problem def
30、inition, the analyst performs a feasibility study. The study, a brief capsule version of the entire systems analysis and design process, attempts to answer three questions:1. Can the problem be solved?2. Can it be solved in the users environment?3. Can it be solved at a reasonable cost?If the answer
31、 to any one of these questions is no, the system should not be developed. Given a good problem definition and a positive feasibility study, the analyst can turn to planning and developing a problem solution.AnalysisAs analysis begins, the analyst understands the problem. The next step is determining
32、 what must be done to solve it. The user knows what must be done; during analysis, this knowledge is extracted and formally documented. Most users think in terms of the functions to be performed and the data elements to be manipulated. The objective is to identify and link these key functions and da
33、ta elements, yielding a logical system design.Start with the systems basic functions. The key is keeping track of the stock-on-hand for each product in inventory. Inventory changes because customers purchase, exchange, and return products, so the system will have to process customer transactions. The st
