Each entry of client in the wait list forms a 'Wait List Entry'. Wait list entry can be in the 'Open' state if the client is waiting for the resource or it can be in the 'Allocated' state if the client has been allocated the resource or it can be in the 'Removed' state if the client has been removed for some reason or it can be in the 'Expired' state if the expiry date of the wait list entry has been reached. The position of a wait list entry can change when a new entry is added or an existing entry is either removed, allocated or expired.

Example

A wait list is created for a provider Carrey's Child Care with two clients, James Smith with position 1 and Lind Smith with position 2 in it, waiting for place to become available. Once James Smith is allocated a place, the wait list entry status is changed to 'Allocated' and the wait list entry for Linda Smith will have its position renumbered to 1.
