2.2 Goals
A Reduction in human and equipment costs;
At present, the student management system is still using manual management or some general management software.
Manual management is to rely on the staff to use paper and pen records to replace Computer Management, the workload is large and easy to cause management confusion, loss of membership consumption information, etc. often occur.
General management software is lack of pertinence, there are many unnecessary modules in the software. Thus the use of more complex, difficult to get started, resulting in a certain amount of waste of resources, not easy to manage, to a certain extent, increased the workload.
This project proposed the development of the system combined with the current trend of social development, the full use of mobile phone software and internet, computer operations, reduce the cost of manpower, equipment is only a system back-office management computer can be.
b improvement of processing speed;
The system obtains the data conveniently, the precision is high, the real-time is good, compared with the artificial processing computation, the data processing speed has greatly improved, especially in the data analysis and the graph display aspect.
C Control accuracy or increase of production capacity;
The accuracy control is pre-set by the developer, which can make the accuracy consistent and maintain at a certain level, and the system efficiency is greatly improved.
D Improve the management of information services;
The personal information is provided by the student, the verification of the information is executed automatically by the software, once the information is saved, it is submitted to the system database, and the system encrypts the information.
E The improvement of automatic decision system;
In many parts of the software, there are automatic decision-making systems, such as judging whether the two courses clash in time, judging whether the course capacity is full, and judging the two students who submit the same course to choose which Teacher's course. This allows the system to have strong automation capabilities, reducing the artificial decision-making.
F Improvement in personnel utilization.
The automation of the system makes the requirement of the operator be reduced and the utilization rate of the personnel increased.
2.3 Items, assumptions and limitations
Managers using the system need to purchase a computer, architecture network. To complete the development of the information management system, the biggest problem is the management system, how to develop a more general standardized system, and on this basis to achieve networking, because the system to be students, teachers, staff and so on, so the whole system Management module to be simple and complete, system security to high, System operation to be stable and run fast, the system is easy to operate.
The system is developed by developing tools such as the C + + language and VS2010 platform, and the operating system works smoothly. But in order to ensure the normal operation of the system must have specialized personnel to maintain the system, timely update system.

The influence of 4.4.3 on the user's Unit organization
The proposed new technology for the system is completely based on the original system, so users do not have to consider the new system to bring the personnel training and so on.
The impact of 4.4.4 on development
The development process requires the user to work closely together to accurately articulate the requirements.
The impact of 4.4.5 on expenses
The proposed system is to improve the original system in the high expenditure of the shortcomings, so the new system once used in the expenditure of funds will be very good improvement, users in the use of a new system only need to spend a certain amount of money to purchase a portion of the computer and software to achieve automation.
4.5 Limitations
After rigorous analysis, we can know that the original system has a large limitation, such as the technology is too old, the personnel workload, system maintenance and expenditure is huge, personnel and equipment, low technical content, and so on a series of shortcomings, all of which are clear need a new era of information to adapt to the new high-tech system. So it is necessary to develop such a system.
4.6 Feasibility of technical conditions
In terms of the development techniques currently in use, it is recommended that the functional objectives of the system be met, and that the development work can be completed within the prescribed deadlines using existing technologies
