1 business needs

1.1 Background, business opportunities and customer needs

University teaching basic or traditional mode of teaching, although most colleges and universities have set up their own campus network, but not a good use of network resources.

In my school, for example, the general process of the education and teaching activities teachers write lesson plans, lesson planning, classroom lectures, issuance of courseware, classroom questions, assignments, recovery operations, correcting homework ... and so the cycle courseware issuance U disk copy to the student, the job turned over 98 more than the traditional paper-based job this. According to incomplete statistics, due to the development of the information society: more than 80% of the students have their own computer and Internet connection; 95% of teachers have access to the Internet computer. The students and teachers have hardware conditions, However, never be able to make good use of these resources, at the same time, due to the limitations of time and space, the exchange of teachers and students little time.

According to our survey, the students need such a platform, to make up for the lack of knowledge in the reality, the same, teachers and school management department also wishes to improve the quality of teaching, and to enhance the communication between teachers and students.

1.2 Business Objectives (BO) and success criteria (SC)

BO-1: The initial release of the first semester, the students' failure rates dropped, excellent rate of increase in staff and student exchange, the improvement of the relationship between teachers and students. Students to reduce the dependence of U disk.

BO-2: on the basis of the above, the indicators increased. SC-1: second semester, utilization of the system is 50%.

SC-2: The second semester, 75% of the utilization of the system, and gradually increase the satisfaction of the teachers and students of the system.

1.3 business risk (RIsk)

RI-1: evaluation of teachers in schools standards may not be changed, which requires that each teacher has a strong sense of responsibility.

RI-2: some old teachers on the computer's ability to operate, difficult to use the risk.

2 Solutions prospects

2.1 vision statement

The high-speed development of network technology, and human resources to achieve a high degree of sharing, and fundamentally change the human way of information exchange.

Currently, our students and teachers on the utilization of network resources is very low, or the use of the traditional teaching mode, however, the range of curriculum subjects, more practical courses lessons, some courses, students in the class are not well master, our online teaching system able to meet the needs of the students, to meet the requirements of the task of teaching in schools.

For those who want to chat, or ask questions of teaching done through network teaching system for students and teachers, the system is an Internet-based applications, can people use. Breaking the limitations of time and space, better school education and teaching.

2.2 The main features (Feature)

FE-1: Students can visit the website information, find information, download files, submit jobs.

FE-2: Teachers can visit the website enter Course Description, upload courseware files, correcting homework, announced, modify and update messages. FE-3: teachers and students can communicate through the forum.

FE-4: Administrators can page maintenance as well as approval of the application for registration of the user.

2.3 is assumed (AS) and dependent (DE)

AS-1: net, PC, Server. AS-2: timeliness.

DE-1: After may relate to the interaction with other systems.

3 Range and Limitations

3.1 initial version and subsequent versions of the range

3.2 limitations (LImitation) and exclusion

LI-1: Version 1 only for the teachers and students of South China University of Technology.

Part III: Software Requirements Specification

5 Introduction

5.1 Goals

The software requirements specification describes the network teaching system version 1.0 software functional requirements and non-functional requirements. This document plan implementation and verification system, the correct function of the project team members to use. Unless otherwise stated elsewhere, all requirements specified here have a high priority, and should be in version 1.0.

5.2 scope of the project and product characteristics

The network teaching system "allows teachers and students to complete educational activities, and another through the network can communicate through this system. The detailed description of the project, please participate in the Network Teaching System prospects and the scope of the document. The title of this part of the initial version and subsequent versions of the range listed in accordance with the schedule in this version all or part of characteristics.

5.3 References

(2) Shang Junjie, Li Fang music written by the higher education network teaching system design, implementation and analysis "

6 general description of

6.1 product vision and planning

Network teaching system "of schools, a new system, it makes up for teaching and learning as well as management of inadequacies. The evolution of the system would be expected to be copied into several versions, the final completion of the remote Correspondence to achieve goals at home to go to school.

6.2 user class and user characteristics

2. Participant related classes

Some other class:

The relationship between classes:

6.3 Runtime Environment

6.4 Design and implementation constraints

Schedule requirements: the system development work must be done in the three-month period, through the acceptance of and put into the campus test run. Funding requirements: development funds of not more than 20,000 yuan.

6.5 User documentation

1.The system will provide a layered and cross-linked HTML online help system, describes and demonstrates all system functions.

2.If you are a new user to use the system for the first time, according to the requirements of the user, the system can provide an on-line tutorial, so that users can use the the static tutorial menu to the concrete practice of how to use this system. The system will not this template stored in the database, it will not submit.

7 System Features

7.1 students download file

1.Description and priority

2.Incentives / corresponding sequence

7.1.1 Description and priority

The student's identity is verified using the network teaching system, in particular, can download the files, teachers canceled or changed files, priority is high.

7.1.2 stimulus / response sequence

The stimulus: students download the file, can be one or more. Response: The system asked students download details. Stimulus: the teachers' request to update the courseware.

Slightly

9 Other non-functional requirements

9.1 Performance Requirements

There should be a perfect backup measures to protect the data can be restored to a key modifications in case of a hardware failure, you should be able to ensure that the data is not being destroyed.

9.1.1 accuracy

Date Time: business information is accurate to the second operation log information is accurate to one hundredth of a second.

Other data: the output statements, the accuracy requirements of the form.

9.1.2 throughput

Should ensure that more than 1,000 people using the system at the same time able to get timely and correct response.

When the system encounters a possible illegal operation by the user and input illegal data, and related software or hardware components of the operating conditions of the defects or abnormalities occurred, should be able to continue to run correctly current function, to ensure data consistency errors does not occur, or with the recovery function, or to prompt the user selected by the user.

9.3 flexibility

The system should be scalable, increase, modify, set aside for future development interface. New or expansion subsystem, new or expansion function, deletion or modification will not disrupt other subsystem functions. Add or modify can easily be achieved by means of custom. The structure of the system should be able to keep up with changes in technology, and not backward technology, technology changes will not affect the existing work.

9.4 integrity

The system should have the functionality to prevent unauthorized access to the system to prevent data loss or tampering, to prevent the virus from entering into the system to prevent private data. To ensure the integrity of the data correlation. User access to records, data and access must be fully protected by a specific method, network facilities, hardware facilities to establish appropriate protection.
