Introduction:
With the rapid development of society, the influence of computer is comprehensive and deep. With the continuous improvement of people’s living standards, people’s requirements for vaccination in daily life are also constantly increasing, and the number of vaccination is constantly increasing, making the development of vaccination platform a necessary and urgent thing. Vaccination platform is mainly through computer, through the vaccination platform required information management, increase users’ choice, but also convenient for the vast number of users’ information query, modification and timely understanding of user information. The vaccination platform brings more convenience to users, and the system works with database management system software to meet users’ needs. The application of computer technology in modern management makes computer become an important tool for people to apply modern technology. It can effectively solve the problem of convenient and comprehensive access to information and improve efficiency. This vaccination platform mainly involves programs, databases and computer technology. Covering a wide range of knowledge can greatly improve the efficiency of system personnel.
Functional design:
The structure diagram of the vaccination platform shows:
Log in to the system structure diagram, as shown in the figure
Administrator structure diagram, as shown in the figure.
