This type of business is a good candidate for a distributed object system because many of the system’s users are geographically dispersed. Commercial travel agents, for example, who need to book passage on Titan ships will need to access the reservation system. Supporting many—possibly hundreds—of travel agents requires a robust transactional system to ensure that agents have access and reservations are completed properly.

Throughout this book we will build a fairly simple slice of Titan’s EJB system that focuses on the process of making a reservation for a cruise.
