Objective Design a distributed system to utilize a java-generated web service for providing flight availability information through a logic (processing) tier.

Design Considerations for Software Architecture Three-tier architecture ◦ Presentation tier  Will follow the Model View Controller (MVC) architectural pattern provided by the Spring MVC  Will include JavaServer Pages, which contain the User/Interface components

Design Considerations for Software Architecture Three-tier architecture ◦ Logic tier  Internal service exposed by George Mason Air Reservation to its client. Spring-Core bean container is used to initialize the beans, manage all transactions exposed by the service, and to persist the entity beans.  Flight availability web service, which provides data of current flight information. This web service interacts with our internal George Mason Air Reservation service.

Design Considerations for Software Architecture Three-tier architecture ◦ Data Tier  Hibernate 3 is an object-relational mapping utilized to map objects to tables using the HyperSQL database
