Creating synthetic key

Hi experts!

I'm having a problem with a project where I have multiple tables which have a lot of linking fields. I have searched about synthetic keys but I just can't figure out how to use those keys in this case. I hope you can help me.

I have 5 tables: Employees, Absences, Invoices, Salaries and Cost Centre Stucture.

My biggest problem is the cost centre structure which connects employees and invoices.

I attached some sample

Thank you in advance!

Thank you for you quick answer! I just found out that I had a small mistake in my example. Here's a right now.

I would prob need a master calendar too?

The problem is this:

I have a cost structure which has 5 levels.I can connect invoices to the "deepest" level which is cost centre. I can also connect employees to this structure but I can connect that only on the Cost structure 3 level. Every month I get new information about the employees, invoices, etc. Cost structure updates every year.

Hi,

If we have multiple linking fields, we have to do link table.By using link table we can do data model without synthetic keys.

For reference find attached file.
