Database-related concept primary key: A row of data uniquely identifies the table, cannot be empty, and cannot be repeated. Make sure that each row of data is unique. Index: is a data structure used to speed up database queries and performance. Adding an index is to add a directory to the field for easy reference. Indexing can speed up the query of fields. The index takes up extra space. The index will increase the time for data insertion, update, and delete operations. Stored procedures: is a group S Q L A collection of statements is used to implement some complex functions, such as addition, deletion, modification and search, or some business logic. Fast performance. Stored procedures can improve security. Debugging is difficult. Poor transplantability. Version management control troubles. Share 2 0 2 5 0 1 3 1 Backend ► Basic concepts of operation and maintenance rights management system User: Sometimes it is also called an account, which represents the user of this system, that is, the actual personnel. Permissions: It means whether you have the right to do this, such as viewing the revenue of the software and uploading the code. Role: A collection of permissions. Generally, an employee needs several permissions for work, but they are all programmers or finances. Then the same type of person needs the same permissions. Collect these permissions to be the role. User group: A collection of users, when there are fewer employees, but when there are many employees, they need it. For example, if there are 10 employees and they need to do the same thing, then build a group and put all these 10 employees in this group. In this way, you don’t have to care about these 10 employees anymore, just give group permissions directly.
