Write a three to four (3-4) page paper in which you:
1. Create a package diagram of the problem domain layer using the communication diagrams and the CRUDE matrix through the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.
2. Perform and explain the verification and validation walk-through of the package diagram.
3. Create a set of invariants for attributes and relationships and add them to the CRC cards for each class in the structural model using Object Constraint Language (OCL).
4. List the classes in the structure model. Choose one (1) class and create a contract for each method in that class. Note: Be sure to use OCL to specify the preconditions and the post conditions.
5. Create a method specification for each method using both structured English and activity diagram for the algorithm specification through the use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia.Note: The graphically depicted solution is not included in the required page length.
6. Use at least two (2) quality resources in this assignment.Note: Wikipedia and similar Websites do not qualify as quality resources.
Your assignment must follow these formatting requirements:
• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
