The problem domain

Our project will be based on a hypothetical Hotel Reservation System, which is targeted for use by an administrative staff of a hotel. The system consists of three basic functions as follows:

Let's look at the high level architecture of the sample hotel reservation application that we are going to discuss in this chapter:

The hotel reservation system comprises of three fundamental entities; Guest, Room, and Reservation. Each guest is identified by name, address, and age. The rooms are identified by room number, room type, and room size. A room reservation is done by assigning a guest to a room.

We are not going to make our project too complicated since our focus is to derive a set of web services for testing with soapUI in the next chapters. Therefore, we deliberately omit some interrelationships between these entities. For example, we assume that a guest can do only one reservation at a time.
