一个crm系统数据设计问题
如题,有个员工表,里面有员工ID,名字,电话,地址,部门等等信息。如果部门不是总部,则需继续向上汇报。
现在需要设计一下数据库:
1.选择一个员工,写出该员工的汇报链。
2.如果一个部门经理,列出该部门下所有的员工。
我想到的思路使用递归解决,但是考虑到量大的话,可能效率不行。
请问有什么好的优化方法。如果用递归,请给出一些例子,如何做。谢谢

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
