1 performance management system-analysis report (I don't know how to post a data flow chart here, so I posted relevant pictures in the space) (In addition, the data dictionary is in tabular form, but it will change when I post it here. )

I. Introduction

1. system name: student achievement management information system

2. Development goal: To develop a student achievement management information system with simple operation, friendly interface, flexibility, practicality, safety and reliability.

The development of the system is aimed at educational administrators and teachers, which can improve the efficiency of statistical analysis of school students' grades, reduce the burden of educational administrators on student performance management and statistics, and improve the standardized management of school students' grades.

The score management system can collect and sort out students' scores in time, so that the relevant departments of the school can obtain reliable information of students' scores in time and facilitate management.

3. Main functions:

The users of this system can be divided into the following aspects according to their users-administrators and teachers of the Academic Affairs Office:

(1) After logging in, the administrator of the Academic Affairs Office can enter the educational administration personnel module, where you can query personal information, teachers' residence title salary, student information, grades and exit the system.

(2) Teachers should be able to enter, add, modify, delete and query students' scores when logging into the teacher management subsystem; Query teacher information, modify personal login password, modify personal information, etc.

(3) the calculation and statistics of students' scores in single and general subjects, such as total score, average score, highest score and lowest score, are automated; Information can be queried by class and individual; Information can be published on the network to realize data sharing;

(4) can automatically check the input error.

4. Development background

Every school needs to make a statistical analysis of the final exam results at the end of the term, which must be completed within nearly one week after the end of the exam. Statistical analysis of a large number of achievement data is time-consuming and laborious, and it is easy to make mistakes if it is only done by hand. With the rapid development of computer technology, computers are rapidly popularized in daily management applications, and it is imperative to use computers to manage students' grades. Therefore, it is necessary to develop a complete, safe, reliable, fast and simple performance management information system to meet the needs of schools for performance entry, statistics, inquiry, reporting and printing.

Two. System objectives and feasibility of development

1. System goal:

(1) To provide the administrators of the Academic Affairs Office with the information of students' basic grades in each semester, grade and class as the basis for summarizing, analyzing, evaluating and summarizing their grades.

(2) It is convenient for teachers in each class to record and count students' grades, improve work efficiency and reduce the burden; Summing up experience and improving teaching quality.

(3) Realize the rapid and convenient processing of a large number of results data information, and complete the processing requirements such as input, addition, modification, deletion, statistics, query and sorting of results.

(4) output printed transcripts and various performance reports.

2) The system has good manageability and maintainability;

3) The input interface of the system is friendly, the operation is simple and easy, and the input workload of users is reduced as much as possible;

4) Allow multiple data input methods, realize multiple queries, and allow fuzzy queries;

5) The data is normative and holistic, which facilitates the comparative analysis between the data.

(4) System feasibility analysis:

A. Technical feasibility: The system requires to run in an environment above windows2000, and the background database adopts access2003, using SOL programming and connecting the database through ADO, which are relatively easy to realize at present. The program stores some data that need to be called frequently in memory, which can improve the running speed of the program.

B. Economic feasibility: Economically, using this system can improve the efficiency of grade information management, provide higher efficiency for educational administration personnel and save the expenditure of human resources.

C. Feasibility of management: At work, the amount of information that the academic staff manages students is very large. The development of this system can greatly improve the work efficiency of educational administrators. It is convenient to store and modify the results at any time in the future and inquire about the results information. It is a more humanized management system.

(5). Conclusion of system analysis:

From the above analysis, we can develop this system.

Three. Overview of current system

1. Survey of current system status

The existing student achievement management system is mainly aimed at the storage and statistics of achievement data information, and the system design is cumbersome, the management is not professional enough, too many people are needed, and the security and confidentiality of the system are not good; The query function is simple and the data enjoyment is not high.

2. Description of system requirements

(1) The system needs to enhance the query function on the basis of data entry, storage and statistical automation;

(2) We should be able to make full use of the Internet to expand the enjoyment of information;

(3) Designate administrators, define management authority, standardize management, and improve the security and confidentiality of the system.
