Create a package diagram of the problem domain layer computer science assignment help

Design with UML

Write a three to four (3-4) page paper in which you:

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.
Perform and explain the verification and validation walk-through of the package diagram.
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).
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.
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.
