安全性：由于系统中涉及到大量学生档案、成绩的信息以及课程信息，因此要具

Security: Because the system involves a large number of student records, performance information and course information, and therefore has good security to ensure the safety of school information.  <br>Real-time: better schools through a lot of information stored in the system understand the students, the system needs to be updated, and the system's response time as short as possible, in order to improve efficiency.  <br>Scalability: The system uses modular design method, using the B / S architecture conducive combinations and modifications of the system function, but also conducive to technical maintenance personnel maintenance added. <br>Operability: The system uses a control-style page layout, can make the operation more simple, many options just a mouse click can be completed.

Security: Because the system involves a large number of student files, grade information and curriculum information, it should have good security to ensure the security of school information.  <br>Real-time: Schools are better able to understand students through the many information stored in the system, the system needs to be up-to-date, and the system's response time should be as short as possible to increase productivity.  <br>Scalability: The system adopts the modular program design method, uses the B/S architecture, is conducive to the combination and modification of system functions, but also conducive to the technical maintenance personnel to supplement the maintenance.<br>Operability: The system uses a control-style page layout to make the operation easier, and many options can be done with a mouse click.

Security: because the system involves a large number of student files, performance information and curriculum information, it should have good security to ensure the security of school information.  <br>Real time: the school can better understand the students through a lot of information stored in the system, the system needs to be updated in time, and the response time of the system should be as short as possible to improve the work efficiency.  <br>Extensibility: the system adopts the modular programming method and B / S architecture, which is conducive to the combination and modification of system functions, as well as the supplementary maintenance of technical maintenance personnel.<br>Operability: the system adopts the control page layout, which can make the operation more simple. Many options can be completed only by mouse click.<br>
