$1.$ Your boss has been in the soft ware development

fi eld for thirty years. He has always prided himself

on his ability to adapt his skills from one approach

to developing soft ware to the next approach. For

example, he had no problem learning structured

analysis and design in the early $1980$s and information

B$.$ For the A Video Store problem in Chapters $4($exercises

$($exercise B$)$:

$1.$ Choose one of the classes and create a set of invariants for attributes and relationships and add them to

the CRC card for the class.

$2.$ Choose one of the methods in the class that you

chose and create a contract and a method specifi cation for it$.$ Use OCL to specify any pre$-$ or

postcondition and use both Structured English and

an activity diagram to specify the algorithm.

I. Create a set of inheritance confl icts for the two inheritance structures in the class diagrams of exercise H$.$

Minicases $325$

engineering in the early $1990$s$.$ He even understands

the advantage of rapid application development. But

the other day, when you and he were talking about

the advantages of object$-$oriented approaches, he

became totally confused. He thought that characteristics such as polymorphism and inheritance were

an advantage for object$-$oriented systems. However,

when you explained the problems with inheritance

confl icts, redefi nition capabilities, and the need for

semantic consistency across diff erent implementations of methods, he was ready to simply give up$.$ To

make matters worse, you then went on to explain the

importance of contracts in controlling the development of the system. At this point in the conservation,

he basically threw in the towel. As he walked off $,$ you

heard him say something like $$I guess it$$s true, it$$s too

hard to teach an old dog new tricks.$$

Being a loyal employee and friend, you decided

to write a short tutorial to give your boss on objectoriented systems development. As a fi rst step, create a

detailed outline for the tutorial. As a subtle example,

use good design criteria, such as coupling and cohesion, in the design of your tutorial outline.

$2.$ You have been working with the professional and scientifi c management $($PSSM$)$ problem for quite a while.

You should go back and refresh your memory about

the problem before attempting to solve this situation.

Refer back to your solutions to Minicase $3$ in Chapter $7.$

a$.$ For each class in the structural model, using OCL,

create a set of invariants for attributes and relationships and add them to the CRC cards for the classes.

b$.$ Choose one of the classes in the structural model.

Create a contract for each method in that class. Be

sure to use OCL to specify the preconditions and

the postconditions. Be as complete as possible.

c$.$ Create a method specifi cation for each method

in the class you chose I want the answers in detials and draw diagrams if questions need please?
