== Use-case model diagram ==

A use-case model diagram is optional for this phase. The main use-case structure is documented textually through the actors, use-cases, and detailed use-case scenario pages listed above.

== Selected use cases for detailed realization ==

The following use cases are selected as the most important database usage scenarios for the Room Reservation System:

* [[UseCase0001|UC0001 - Search available rooms]]
* [[UseCase0002|UC0002 - Create reservation request]]
* [[UseCase0003|UC0003 - Approve or reject reservation]]

These use cases were selected because they cover the central database operations of the project: reading available room and equipment data, inserting reservation requests, inserting requested equipment records, updating reservation status, and inserting approval decisions.
