System Overview:
First administrator: The basic data set, the database must exist in this information and the current user information, or not use AH. You can then add different users, such as other administrators, operators, and general users. The administrator has the most privileges and the operator is the second. Administrators and operators can add and register to general users. (Here is not understand the general user and student relationship, not the same but the same permissions, add the general user when the student table is not updated, the registration of student information when the general user did not increase accordingly.) Add and remove users, the prompt cannot delete the user who is logged on.
Second. Operator: Register the student card number, insert into the student table, where Cardno and Studentno must be indicated as numbers. You cannot write anything in the check boxes for sex and type. The registration amount cannot be less than the set amount. Returns the registered amount to the Recharge Amount text box. We don't know what this text box is for. Update student tables.
Third. After the operator registration is complete, the general user student can go up and down, and carry on the general user all operation. The average user and student here is a person, if so, how can you see the other students on the computer record and consumption it? Personal feeling is not ah. (Still don't understand)
Fourth. After the student login, according to the basic data set has certain consumption, according to different time period and the temporary user and the fixed user to divide the different consumption quota. When the consumption to the card amount is insufficient, you can let the operator or the administrator to recharge the card amount, after the recharge can be charged to the amount of inquiry. When the card number is no longer used, you can choose to cancel the card, this is the amount of information can be returned to the query.
Fifth. The administrator completes the checkout operation after all the students have been off the machine, to clarify the relationship between the tables. The checkout information is then aggregated into the daily checkout and weekly closing orders. End of entire operating system process
Finally. To be resolved: When the system exits, the user who is on the machine is automatically off the machine? can be updated to the Line table. Will the information change in Worklog?
