Flight Information
Management System
Chantelle 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
