Here, I have some problem representing a hostel-room-inmate entities.
First an inmate is given a hostel seat,
Then he is allotted a particular hostel,
Then he is allotted a room.
My approach is that the inmate table contains a parent-link to the room table, the room table contains a parent-link to the hostel table.
table hostel(id, name) table room(id, hostel_id, room_no) table inmate(id, room_id, name, etc)
But while at the stage of allotment, the inmate is first allotted a hostel, in which the room_id is to be left blank, thereby meaning that the inmate is not allotted a hostel room and so on…
How do I solve this problem please…
I wanted to use it in Laravel development environment
(NB: I have some idea of creating many-to-many relationship type by creating relationship table, but just asking if there’s better approach than this.)
