You might be tasked with growing a relational database mannequin for an Worker Attendance System. Confer with your studying task for a pattern relational database mannequin. The aim of this method is to offer administration with a historical past of attendance at work and the period of time off taken by staff categorized by kind of day off taken, e.g. trip, sick, and household go away, and so on.
The deliverable for this task should embody:
• An inventory of the tables on this mannequin to be used within the Worker Attendance System. Every desk should comprise the highest three attributes.
• An inventory of software areas equivalent to Payroll which would be the supply of the transactions essential to replace the Worker Attendance System.
• A system diagram of the Worker Attendance System together with databases and supply knowledge purposes.
• Transient narratives explaining your rationale behind the contents of the info mannequin, system diagram, and listing of supply purposes
