2 System analysis The feasibility analysis. The purpose of the feasibility stuy is to etermine whether the problem can be solve with minimum cost as soon as possible. Economic feasibility Nowaays, the price of the computer has been very low, while the performance has mae consierable progress. An the evelopment of this system brings a qualitative leap for working efficiency of the school, which mainly inclues the following aspects: First, the operation of this system can replace much multifarious artificial labor; Secon, the operation of this system can save a lot of resources; Thir, the operation of this system can greatly improve the working efficiency of the school; Fourth, this system can make sensitive ocuments safer an so on. Therefore, this system is economically feasible. Technical feasibility The evelopment of this system using Microsoft SQL Server 2005 as the atabase of this system, it is a new kin of atabase which supports more users an is suitable for large an meium-size ata amount nees. Using Visual Stuio 2005 as the evelopment environment of the system provies the perfect instruction control statements, the support of the classes an objects an rich ata types, this ensures the safeguar for high performance of the system an meets the requirement of customers, as well as the moularization requirements of the coe, an higher moularization is beneficial to extension an moification of the new system in the future. To sum up, the esign an evelopment on the technology of this system an the conition of the harware are satisfie, therefore, it is technically feasible. Operation feasibility This system is small stuent information an performance management system, which nees small amount of resources. School computer can meet the conitions both in harware an software; therefore, this system is feasible in operation. Requirements analysis. There is a lot of stuents information in aily teaching management, incluing basic amission files, performance information, accommoation information, payment an rewar information, etc. If manual management way aopte in the large amount of information, large workloa, waste of manpower, material an financial resources will bring in information access, preservation an processing. In orer to manage stuent information efficiently an accurately, built up stuent information management system is an effective ways to improve the efficiency of management of a school. Stuent information management system aims to establish a system to manage the various information of stuent. Operators can a, moify, an elete stuent information ata through a visual interface. The analysis of system esign This system is suitable for primary an seconary schools, an its main function is ivie into six categories: Users management: use for users aing, giving ifferent access, moifying an querying of the users. Curriculum management: use to open an moify the course of each semester. 1763

3 Performance management: use for input, moifying, summary an ranks. Stuents information management: a, elete, moify the stuents information, etc. Teaching information management: a an maintain information of instructor, course number, creit number an class, etc. Stuent information query: query stuent performance information in fuzzy way, as well as the unlimite conition query. Stuents score statistics: statistics total scores an the average scores of unergrauate. The performance of the system strives to easy use an is of high expansibility an maintainability. 2) Analysis of system function Permission function: this system has ynamic permissions istribution function. Users can be groupe accoring to users permissions, incluing orinary users, the general users an super users. The orinary users only can query but cannot moify. The general users can only moify an elete within the scope of permission. Super users can moify an elete all information. Input function: provies the corresponing functions of the input for the general users; provies all information access for super users. Query function: provies the function of the query for all users within the limite scope of all information Maintenance functions: provies the corresponing functions of query, moifying an eleting for the general users; provies all information moify an eleting for super users. Exit function: finish an close the system. (3) Purpose on stuents registration system -Saving resource, improving the accuracy of the information. This system can reuce a lot of unnecessary resource, instea of reunant paper management. Save the school energy. The computer storage an fast query function greatly improve the efficiency of the stuent registration management, as well as the precision. Convenient an rapi operation, reuce staff an cut own expenses. Convenient an rapi operation, can reuce bugs in registration information management, an reuce the reunancy of work because of mistakes. An the operation is very simple, which can reuce unnecessary personnel, saving costs for the school no matter on materials or on wages of workers, an increase wealth for the school. (4) Database analysis Stuents registration management system specifically provies preservation, upate, query, maintenance, an print for users nees, which requires the atabase structure can fully meet the various input an output of information, systematically an ynamically store massive correlation ata in orer to access ata in the system conveniently. It iffers from files system in sharing ata, cross access an with of highly inepenent of application programs. Data flow analysis. Data flow chart emphasizes on ata flow an process, which is shown as Fig. 1: 1764

Data ictionary focus on ata information collection, which is on the basis of the ata flow chart, an efine the ata items, ata flow, processing logic, ata storage, an external entity in it. Its role is proviing information about the ata escription in the process of software analysis an esign. The analysis of system process. System flow chart is a traitional tool to escribe the future physical system. Its basic iea is that escribes the components of the future system through graphic symbol in the form of the black box, such as proceures, atabase, form an process. The symbols of system flow chart are similar to that of program flow chart. But there is a funamental ifference between system flow chart an program flow chart. System flow chart is a physical tool to escribe the physical general picture of the system, in which the arrows inicate the irection of ata flow; while program flow chart escribes the process of computer executing a program or escription of a algorithm, an the irection of arrows in this picture inicate controlling information, that is the irection of the program execution.

6 Business goals of system esign. The goal of performance management information system is to establish an avance, efficient, safe, reliable, an can be effectively applie to atabase of stuent performance management information. The system base on C/S structure. This information reflects the business logic of the stuent performance management system, greatly simplifie the teious process of the relate work, an provies a powerful ecision support for management at the same time. Users roles of the system are two major kins: system aministrators an orinary users. The system aministrator can manage users. Orinary users can be ivie into stuents, teachers an other users. Aministrator: manage users, group permission istribution, information query, etc. Teachers: stuents information management, curriculum information management, score management, teaching information management, information query, score statistics, etc. Stuents: scores query, etc. Management function structure is shown as Fig. 5: A mi nis tra tor Function moule Group permission Recor, a, elete, Teachers function structure Fig. 6 Fig. 5 Management function structure Stuents info Courses info Te ac he rs Stuents Teaching info Recor, a, elete, Stuents info Stuents Fig. 6 Teachers function structure Stuents function structure Fig. 7: 1767

Accoring to ifferent selecte permissions isplays the ifferent functions in the main winow. The functions of this form are: isplays the entire functional menu of the system. The principal an irector of grae can conuct the function of basic information setting, class information setting, stuents' basic information management, an stuent performance management. The irector of the grae can only manage the information stuent information management, class information management an performance information management of this grae. Stuent login can only view the personal information an performance. The realization of teachers information setting. The functions of the form: for principal an hea teachers to a, elete an moify information of teachers. The realization of the stuents basic information maintenance. The functions of the form: for principal an hea teachers to maintain stuents basic information. The realization of stuents performance management. (1) Stuents performance import form The functions of the form: import the graes in the Excel files into a atabase. The Implementation metho is to put the Excel file as ata sources of atagirview control, an then insert the ata from atagirview into the atabase. (2) Stuents performance statistics form The functions of the form: to statistics stuents performance information, incluing statistical results of all courses, rankings awars an recommenation an printing performance information. (3) Comprehensive scores query form The functions of the form: comprehensive statistics of performance, incluing the overall ranking, faile situation an performance ranking of each course, an print statistics result. (4) Statistics form of single course The functions of the form: the substitute teacher statistics the performance information of the course, incluing average score, number of faile stuents an stuents with score higher than 90 points. The realization of print function moule. The technique realize this moule is to use encapsulate print class. Print class is a ynamic link library files, in the ynamic link library file, in which performance parameters relate to print encapsulate. Parameters are only nee to put into the functions in using. In using of print class, first the ynamic link library file of print class must introuce into the project, an then a quotation of namespace into the form of print function. Take using DLLFullPrint for example; when a form nees print function, pass parameters to the class of print function is only neee. Conclusions The title of this paper is the stuents information integrate management system base on.net. The evelopment of the system base on eep stuy of school management an relate issues. This system is esigne after a comprehensive investigation an analysis, an integrates professional theory knowlege an skills of computer. 1771
