Situation: Employee Registration System where every employee must have a branch and each branch must have a branch manager. (sorry for Diagram I don't have proper tool)
Table Employee
[ID].... [Branch_ID]
Table Branch
[ID].... [Manager] (ID of employee who manages)
Question: What would be the best way to handle this situation just check for the first employee or remove the manger mandatory check of manager ? Or any other way ? Any help would be appreciated.
