1、1外文原文The Design and Development of the Students' Information Management SystemAs information technology advances, various management systems have emerged to change the daily lives of the more coherent, to the extent

2、possible, the use of network resources can be significantly reasonable reduction of manual management inconvenience and waste of time.Accelerating the modernization of the 21st century, the continuous improvement of the

3、scientific and cultural levels, the rapid growth of the number of students will inevitably increase the pressure information management students, the inefficient manual retrieval completely incompatible with the communit

4、y\'s needs. The Student Information Management Systemis an information management one kind within system, currently information technique continuously of development, the network technique has already been applied in

5、 us extensively nearby of every trade, there is the network technical development, each high schools all make use of a calculator to manage to do to learn, the school is operated by handicraft before of the whole tedious

6、 affairs all got fast and solve high-efficiencily, especially 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 u

7、nderstand accurately with management everyone noodles information. AbstractIt is a very heavy and baldness job of managing a bulky database by manpower. The disadvantage, such as great capacity of work, low efficiency an

8、d 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 i

9、s huge, 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 m

10、anagement system. The whole system design process follow the principle of simple operation, beautiful and vivid interface and practical request. The student information management system including the function of system

11、management, basic information management, study management, prize and 3Systems Analysis and DesignSystemsWorking under control of a stored program, a computer processes data into information. Think about that definition

12、for a minute. Any given computer application involves at least three components: hardware, software, and data. Merely writing a program isn’t enough, because the program is but one component is in a system.A system is a

13、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 hours worked on

14、 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

15、 printed and distributed. For the system to work, people, procedures, input and output media, files, hardware, and software must be carefully coordinated. Note that the program is but one component in a system. Systems A

16、nalysisComputer-based systems are developed because people need information. Those people, called users, generally know what is required, but may lack the expertise to obtain it. Technical professionals, such as programm

17、ers, have the expertise, but may lack training in the user’s field. To complicate matters, users and programmers often seem to speak different languages, leading to communication problems. A systems analyst is a professi

18、onal who 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 ski

19、lls with insight, imagination, and a touch of art. Generally, the analyst follows a well-defined, methodical process that includes at least the following steps:Problem definitionAnalysisDesignImplementationMaintenanceAt
