  2. Overview • Project overview • Database design • Program design • Synchronization issues • User experience • Conclusion

  3. Project Overview • A user may search for a flight between two locations on a specific date. • A user may reserve available tickets. • A user may purchase previously reserved tickets by providing his/her credit card information. • A user may cancel previously reserved tickets.

  4. Project Overview • Three-tier architecture • IDE • Eclipse, Tomcat and Oracle • Programming languages • JSP, JavaScript, Servlet, and Javabeans

  5. Database Design

  6. Database design • CreditCard is a weak entity dependent upon Customer • Passenger is a weak entity to Purchase • Reservation • Originally one-way flight • Later add round trip flights • One reservation may involve two or more flights.

  7. MVC architecture • One of the most popular design patterns of web applications • Example: Struts • Separate UI from business logic • Three components • Model • View • Controller

  8. Program Design • In my program, • JSP pages act as View • Java Servlets act as Controller • Java beans act as Model • Separate entity beans from action beans • Entity beans: getter and setter methods • Action beans: data manipulation and calculation

  9. Program Design

  10. Synchronization • Database level • Oracle: implicit lock automatically • Application level • Synchronized keyword • Java’s synchronization model is based on the monitor mechanism. It is used to protect shared resources from simultaneous access and manipulation in a multi-threaded environment

  11. User Experience

  18. Conclusion • Learn a great deal of the J2EE application development • Realize the advantage of the MVC framework • Understand the function of the system fully • Later changes can be costly
