Solved in 2 steps
- Make use of object-oriented design when it makes sense to do so. Structured design is a viable option when the situation calls for it. Exactly why is this happening, etc.The object-oriented design techniques that are implemented should be structured in such a way that they put a larger focus on modeling and less attention on procedure. This should be done in order to ensure that the methodologies provide the desired results. Give me one reason that should convince you.Use object-oriented design when it makes sense to do so. The use of structured design is suitable when the situation demands it. Why is this happening, and so on?
- What exactly do you mean when you say that patterns and frameworks are different?Object-oriented design should be utilized in all appropriate contexts. Structured design is a viable choice to consider when the situation calls for it. whether there are any potential explanations for this, what they might be, etc.The object-oriented design methodologies that are used should be organized in such a manner that they place a greater emphasis on modeling and less emphasis on process. Give me one compelling argument.
- Question 17. Due to reusability the overall cost of design, code and testing gets reduced. It also reduces the amount of code and therefore the code becomes understandable.Reusability is possible in conventional language but in object oriented languages reusability can be done effectively.What are the types of reusability explain briefly?When you state that patterns and frameworks are distinct, what do you mean?Task description Describe an example scenario where it is applicable to use the composite design pattern. You should not use the assembly-part stock control scenario described in lectures. You can make use of other sources for scenario ideas, but you should reference them appropriately. Your answer should include the following: a) A description of the scenario and the relevant objects in it. b) A class diagram illustrating the use of the composite design pattern. c) A description, with code snippets, of an implemented solution to the scenario without using the composite design pattern. d) A description, with code snippets, of an implemented solution to the scenario using the composite design pattern, making reference to how the implementation in c) was adapted. e) Your answers to c) and d) should include a discussion of data structures used, any association, aggregation, or composition relationships, inheritance relationships, and the use of polymorphism
