Describe how software development productivity can be accomplished by the application of various Creational Design Patterns.  	Describe each of them Question 2 Refer to the Software Solution Scenario described in Appendix A and also OO Software Design Patterns described in Gamma et al (1995) / Smith (2015 to answer the questions below: You have been tasked to carry out the development of an online shopping system for iChipKart store. You are currently working on two use cases of the system: Checkout and Compute Price. An extract of the current analysis and design of these use cases are given in Appendix A. Consider the two software design problems described below. 	Design Problem 1 (Compute Price): During the transition from Analysis to Design phase, you are designing the price computation for ease of incorporating different shipping and handling fees for different locations in the pricing policies. In your design, you also want to ensure that various policies in pricing computation are encapsulated appropriately for ease of maintenance. Suggested candidate design patterns (Proxy, Strategy, Template Method) Use UML diagram to design ComputePrice class. Then write the complete Java class 	Design Problem 2 (Checkout): During the transition from Analysis to Design phase, you are designing the functionality of free gifts for ease of offering and withdrawing the various gifts dynamically and for ease of modifying the price ranges of free gifts. Suggested candidate design patterns (Chain of Responsibility, Composite, Iterator) Use UML diagram to design Checkout class. Then write the complete Java class NOTE: Don’t forget to include relationships (use appropriate symbols, dotted arrow, diamond shape …etc) For each of these design problems, answer the following: a. Choose one of the suggested candidate design patterns that you think best solves the problem. Justify the applicability of your choice. You need to research on various patterns and come up with your choices and justifications. 	 b. Applying scientific principles identify the participants for incorporating the chosen design pattern and modify the class diagram of the use case to show their relationships. 	 c. Critically analyze the patterns and list two benefits of incorporating the design pattern, with respect to the problem.  d. Concerns such as design of security properties and domain specific security is addressed while transiting from requirements engineering to design. Choose any two security design patterns of your choice and research their merits and demerits. Appraise you selected security patterns against the following pattern characteristics: i. Level of Abstraction: Ease with which the pattern can be used in different contexts without redefinition. ii. Completeness: The security speciation that is correct and complete.  iii. Reusability: The pattern should be easily applied and used in different contexts. iv. Pattern Composability: The pattern should be easily used with other patterns. v. Security Composability: The pattern can be used with other patterns without losing any of the security it provides, nor affecting the security provided by the other patterns. vi. Valid-ability: The patterns’ security properties, as well as their implementation and usage, can be easily validated. This validation would preferably be automated.   What to submit: Questions 1 and 2 in a written essay format. You must use the project template given on Moodle to present your answers.

APPENDIX A (Sample of flow charts) Analysis and Design for Object Oriented Software  Online Shopping System for iChipKart Use Case Model Global View (Partial)  Checkout Use Case Brief Description After a buyer adds items to the shopping cart, he/she will check out the purchased items. Items can be Books, Media (CD, hard disks, memory card etc.), TV, computing items and accessories like tablets, thumb drives etc. In order to make their business competitive, iChipKart has decided to give its buyers one of the following memorabilia items as a free gift during the period 1 October to 15 January. The following describes the policy for these gifts:  (1) If the buyer purchases goods worth ≥$25 and

Patterns can be classified for creational, structural, or behavioral purpose. Creational patterns concern the process of object creation. Structural patterns deal with the composition of classes or objects. Behavioral patterns tell the ways in which classes or objects interact and distribute responsibility. 
The Creational Design Patterns.
Creational design pattern concerns the process of object creation.The creational design pattern is the method of creating many different objects. It is the study of class instantiation. The idea is to effectively create objects and to reuse them. The creational design method involves different object creation methods for reusability of code. There are different creational design patterns. They are as follows:
The Object Pool Design Method:
The Object pool allows to reuse objects which will be expensive when they are created again.
Object pool is needed when there are many clients and they all require same objects. Hence the objects are reused rather than creating again a new object which is expensive.
The Singleton Design Method:
In Singleton design method, there exist only one instance of the class. They can be accessed globally and shared by multiple objects.  Thus, in singleton design method there exist only one instantiation of a class
The Factory Design Method:
It has an interface for creating objects from a super class. It also allows the subclasses to alter the type of objects that are created. Thus, there will be an abstract class. Objects that are instantiated can have their own methods.
