There are multiple subsystems in a relatively large system, and each subsystem may have different organization development. If each subsystem is processed by its own users and permission management, then the management and maintenance of the entire system will be very Complex and troubles. First, the maintenance of user information requires administrators to enter and maintain multiple times for the same information. Second, users need to remember more user accounts and passwords. And in the subsystem to turn back and forth in the subsystem. Enter user accounts and passwords, management and maintenance. In order to solve this problem, general projects use single-point landing process mechanism and way to solve this problem. What is single landing?
Single landing is a large system existing multiple subsystems, and when users only need to use a unified login verification system to verify it, then they can freely switch and use in each subsystem. Single point login requirements. 1, need User data management and password management as a separate module in the entire large system. 2, each subsystem uses this module to perform user data management and password management. Single landing benefits: 1, user information Consistency. It is very important and beneficial to ensure the consistency of user information across the system, and it is convenient for maintenance, upgrade of its entire system.
2, the convenience of user operation. He is very convenient and advantageous for users to come back and forth in the system in each subsystem, which is convenient for the user's operation. 3. It is convenient for the system's security module upgrade and maintenance. Since single-point landing is developed and maintained as a relatively independent module, this module is easily developed and maintained. Above these is some of my understanding and ideas, I will summarize the realization of single landing and various systems, I hope everyone will discuss, learn.
