Human resources data model

The HR data model is a transactional fact table with discrete events. This includes the employee-related events along with a few financial events that help us measure productivity. We record the following events in this model:

• Employee payroll
• Employee absences
• Employee training
• Employee hiring and dismissals
• General Journal (GJ) entries related to sales, costs, and expenses
