Requirements for the FlyAndStay LTD System case study
Part 1

Your software house decided to design and build the system using the object-oriented methodology, to allow for more flexible design/build iterations and re-use of design and code. You have therefore now been asked to produce the analysis and design of the new system using object-oriented analysis and design principles and UML.

The UML design should include:
1. Use Case Analysis - A UML Use Case diagram identifying all actors and the Use Cases they are involved with.
2. A Conceptual UML Class Diagram - Show the attributes, some methods and associations for all main classes.
3. Activity diagrams
4. Interaction Diagrams. Using UML object sequence (interaction) diagrams perform an analysis of all main Use Case scenarios (sequence diagrams using Jacobson simple see example bellow).
5. Statechart diagrams for all major classes (state chart diagrams).
6. Design UML Class Diagrams - Show the attributes, all methods and associations for all classes. The design class diagram should also reflect any design patterns that you may consider to use.

1. A section showing the use of Design Patterns in your design, with examples (please do not write about design patterns in general).

1) An ERD for your database.
