I have this problem.
Bascially i have 13 rooms that can be rented out in hour slots
from 9am till 8pm
this only needs to last from 6 days monday to saturday
so bscially i can have all 13 rooms rented out for each our of each day.
but i am wondering how i can create this kind of structure in a database using postgresql.
i would like to use Arrays, compisite types and inheritence where ever possible to solve the solution.
