Structure of the program system

Lists the names, identifiers, and hierarchical relationships between each program in the program system, including each module and subroutine, with a series of charts.

Student Management (Normal) design notes

From the beginning of this chapter, the design considerations for each program in each level are given individually. The outline given below is specific to the general situation. For a specific module, especially a lower-level module or subroutine, many of its entries are often the same as the contents of the corresponding entries in the previous layer of the module to which it belongs, in which case it is simple to illustrate this point.

Program Description

The program is responsible for viewing and partially managing the student's situation. This procedure does not operate the account, that is to say the operator does not move money. Non-resident memory, can be heavy human. You can do this in this program as long as you log in to the system.

Function

Performance

Accuracy: The money is accurate to 0.5 yuan, the time is accurate to the minute, other numbers are accurate to the whole digit.

The loser.

Gives the characteristics of each entry, including the name, identity, type and format of the data, the valid range of data values, and how to enter it. Number and frequency, input media, source of input data, security and confidentiality conditions, etc.

Name	Identity	Data type	Valid range	Input mode
Card	Card_no	Char	10-digit number	Swipe input
Name	Name	Char	5 characters or less	Manual input
Class	Class	Char	4 characters	Manual input
Grade	Grade	Char	5 characters or less	Manual input

Amount	Cash	Money	0~100	No
Time	Time	Datetime	0~240 (min)	No

Frequency: On machine, down machine must output, other conditions according to user needs

Algorithm

Calculates the machine time according to the difference between the time of the machine and the time of the machine, converts it to half an hour according to the machine (minutes), and computes the amount used

Formula: on-Machine Amount = time * Unit Amount (time greater than 5 minutes)

Process logic

Use diagrams (such as flowcharts, decision tables, etc.) with the necessary instructions to represent the logical flow of the program.

Interface

In the form of a diagram to illustrate the program is subordinate to the previous layer module and subordinate to the program of the next layer of module, sub-program, indicating the parameter assignment and call mode, the program is directly related to the data structure (database, data text volume).

3.10 Annotation Design

Describe the notes that are intended to be arranged in this program, such as:

1. At the beginning of the module, a note explaining the time the module was written, the author, and its basic functions

2. Comments added at each branch point indicate the conditions to be provided by the student on the machine

3. Describe the time variable and the cost variable, and indicate the time spent on the machine and the amount of money spent.

4. Note that the different circumstances of the students on the charge of charging different rules, point out the specific calculation method.

Restriction conditions

You must ensure that the program is properly connected to the server.

Test Plan

Carry on the student to the machine, the machine test, verifies the data accuracy. The information of the students on the machine and the amount of recharge are equally sure of the accuracy of the search.
