Comprehensive Review of Design Patterns in Software Engineering and Implementation Techniques

This document provides an in-depth review and summary of essential design patterns used in software engineering, focusing on both behavioral and structural patterns. Key patterns discussed include the Command, Observer, Strategy, and Proxy patterns, along with practical examples for implementation. The material is tailored for students preparing for exams and includes design project topics relevant to the patterns. Additionally, insights into Java data structures and interface implementations relevant to common design patterns are provided to aid understanding and practical application.

  1. CIS 644 Tues. Nov. 30, 1999 W15A … patterns

  2. schedule: 30: patterns 2: review for exam 7: design proj 9: design proj email exam2

  3. patterns: Coad … mostly PD patterns Gamma… mostly implementation patterns

  4. Coad#1: collection - worker actually: worker - users - collection as: clerk - customers - videos

  5. Coad#3: Participant- Transaction Coad#5: SpecificItem - Transaction as: Customer - Rental Video - Rental

  6. and Coad#6: Transaction - TransLineItem as: Rental <>- RentalLineItem

  7. Coad#7: Transaction - SubsequentTrans as: GrainReservation - TruckDelevery

  8. Coad#14: Container - Contents as: Flight <>- Reservation

  9. Coad#18: CompoundPart - Part same as: Composite - Component where: Component = PrimitiveComponent | Composite

  10. Coad#20: Plan - Step (CIS project) as Budget <>- BudgetPeriod

  11. Coad#26: Proxy - SpecificItem as : CachedItem - Item as: LocalItem - ServerItem as: EditPage - SourcePage

  12. Coad#27: Publisher - Subscriber same as: Obervable - Observer as: PD_Item - Item_View

  13. Java data structures: [Bailey1999] common "behavior" patterns: public interface Enumeration { boolean hasMoreElements(); Object nextElement(); } public interface Iterator extends Enumeration { … void reset(); Object value(); }

  14. Java examples for three other "behavior" patterns: Terrazas ..visitor pattern Liu ........ command pattern Zhang ... state pattern

  15. Coad chap 4: adaptor patterns: as: multiple adaptors multiple thread access

  16. diagrams for other Gamma patterns: http: //ksi.cpsc.ucalgary.ca/~kremer/patterns/

  17. Creational Patterns Abstract Factory Builder Factory Method Prototype x Singleton

  18. Structural Patterns x Adapter Bridge x Composite Decorator Facade Flyweight x Proxy

  19. Behavioural Patterns Chain of Responsibility x Command Interpreter x Iterator Mediator Memento x Observer x State Strategy Template Method x Visitor

  20. reusable items: patterns: packages: interface, classes components: frameworks: software tools:
