Schema - Do you create a consistent primary key column on your tables?

Make sure you created a consistent primary key column named Id on your tables.

Employee.ID, Employee.EmployeeId, Employee.EmployeeID, Employee.Employee_Code, Employee.Employee

❌ Figure: Bad example

Employee.Id

✅ Figure: Good example

Why?

• We shouldn’t capitalise ID (identifier) as it is an abbreviation not an acronym.
• Using the approach [TableName]Id, e.g. EmployeeId, is redundant as we already know the context of the Id.
