I have a database.
I have 4 tables.
Employee table
Project Table
Sales order table
Customer table
================================
SalesOrderId is unique
EmploeeId Is unique
CustomerID is unique
ProjectId is unique
What would be the relationship for these tables?
Should I create 5th table that has salesOrderID and ProjectID and the primary key is the combination of salesOrderId and ProjectId?
Is the whole process correct?
