Flight Information Management SystemChantelle Erasmus

Motivation• Learn about the client/server model with use of database• How the client interacts with the server• How server interacts with database

Goals• Create a client/server application with ability to:• Display flight information to user depending on information

requested• Only display information that user is authorized to view• Add/Update/Delete flight information if user has proper

authorization

Implementation Details• Use Java Swing for GUI• Use Java• Use Oracle database• Java Persistence API• Developed on Windows 7• Netbeans IDE

Client Design• Input is gathered from user through GUI• Has main thread for GUI and sending messages• Message sent to server requesting information

• Has receive thread for receiving messages from server• Display information through GUI to user if applicable

Server Design• Java Persistence API used for communication with the

database• Has main thread for sending messages to client and Java

Persistence API calls• Has receive thread for receiving messages from clients

Database Design• Store all information about flights that may need to be

accessed• Store user credentials and authorizations• Very basic; add more information in future
