1 Introduction 1.1 Purpose of writing

The requirement is written in order to standardize the writing of the software, aiming at improving the visibility in the software development process, making it easy to control and manage the software development process, and proposing the software development process of the data Structure classroom Practice test system, and it is also the foundation of the project planning, the outline design and the detailed design. It is the basis of maintenance personnel for internal maintenance, information updating, acceptance and testing, and also facilitates communication and collaboration between programmers and customers. The expected reader of this requirement is the development of the software for the classroom exercise test system of data structure to compose the personnel and the customer.

2 Task Overview 2.1 goals

With the development of Intemet, the network practice system has been applied more and more widely. Especially in recent years, the rapid development of higher education in China, computer network and computer room teaching equipment have been popularized, therefore, the use of computer networks to test the need is very urgent, the system can be the classroom practice of software, to facilitate the students to exercise independently, improve the quality of education.

Visual Studio 2010 As a development platform, SQL Server provides database support.

2.2 Features of the user

The end user of the software is a learner who is learning the data structure

Operators can master the basic operation of computer and Android phone, maintenance personnel have a certain degree of computer expertise, understanding of database system management and maintenance.

2.3 Assumptions and constraints

In the project development process, the developer is assigned in place, can complete each work task as scheduled.

The development period is two months.

3 Requirements 3.1 Provisions of the function

Figure 3.1.1 Common user module use case diagram

Figure 3.1.2 Administrator module use case diagram

The preliminary design of the functional module is divided into two modules, namely the Administrator module and the ordinary user module.

Administrator module:

Question Bank Management: Used to add, delete, modify questions.

Account management: Used to modify account basic information and password, etc.

User management: To achieve the Administrator's basic information, permissions and password management for ordinary users.

Normal User module:

Account Management: Modify the user's basic information and password, etc.

Test: Divided into types of exercises and mock exams, which can choose the difficulty of the exercise.

3.2 Specifications for Performance 3.2.1 Accuracy

It is agreed that the decimal of all input and output of the system is reserved to one decimal place.

3.2.2 Time Characteristic requirements

A Response Time <=5s;

b Update processing Time <=5s;

C Data conversion and Delivery time <=10s;

3.2.3 Flexibility

A The interface operation mode of the system should be flexibly transformed with the change of user's opinion;

b The system can not stop operating with the change of the operating environment;

3.3 Input/output requirements

Data type :

Character data

char[(N)]: holds a fixed length of N character data, 1<=n<=8000

varchar[(N)]: Holds variable-length N-character data, 1<=n<=8000

3.4 Data Management Competency Requirements

The data that needs to be managed is divided into five tables: the user table, the score table, the selection table, the blank list, and the simple answer sheet.

3.5 Fault Handling requirements

Normal use should not be error, for the user's input error should be given appropriate correction tips. If you run into an unrecoverable system error, you must also ensure that the database is intact.

3.6 Other specialized requirements

No.
