Analysis
Model design starts from attribute that indicates all system. In this case it is attribute VacationDays. On the level 1 it is finalized into three physical attributes age, service, days. In the following division is made and the relation between attributes is showed. Level 3 is the last level of ARD diagrams.
The system which counts vacation days was designed in one XTT table.
