1	Why do we need Design Pattern? A bit of the history Good software practices and principles The Gang of Four (GoF) Overview of the Design Patterns Essential software engineering disciplines How patterns are documented? Class Abstract Class Interface Aggregation & Composition Multiplicity Association Role Attributes Operations and Methods Abstract Factory Builder Factory Method Prototype Singleton Adapter Bridge Composite Decorator Façade Flyweight Prox Chain of Responsibility Command Interpreter Iterator Mediator Memento Observer State Strategy Template Method Visitor Inheritance Polymorphism Abstract Classed and Methods Interfaces Access Modifiers	Notes to Gano Excel Students: Materials updated on 4/Sep/2025 10pm Intro.pptx Diagrams.xlsx OOP.pptx Introduction to OOP in C# OO(C#).zargo OOP.zip
2	How a Simple Factory Works? Building the Simple Factory Using the Factory Consequences of Abstract Factory Example How a Builder Works? Consequences of the Builder Pattern Example When to Use a Factory Method? Example Using the Prototype Deep Vs Shallow copy Cloning the Class Using the Prototype Pattern Dissimilar Classes with the Same Interface Prototype Managers Consequences of the Prototype Pattern Example Creating Singleton Using a Static Method Exceptions and Instances Throwing the Exception Creating an Instance of the Class Providing a Global Point of Access to a Singleton Example	Day2.xlsx Patterns Singleton FactoryMethod AbstractFactory Builder Prototype Excercises Factory Method Builder
3	Making an Adapter The Class Adapter Two-Way Adapters Pluggable Adapters Example Extending the Bridge Windows Forms as Bridges Consequences of the Bridge Pattern Example Basic understanding of GC based system An Implementation of a Composite Doubly Linked Lists Consequences of the Composite Pattern A Simple Composite Example Handling events in a Decorator Layout Considerations Multiple Decorators Decorators, Adapters, and Composites Example What Constitutes the Façade? Consequences of the Façade Example Sharable Objects Copy-on-Write Objects Intrinsic and extrinsic Example Copy-on-Write Comparison with Related Patterns Example	Day3.xlsx Patterns Composite Decorator Façade Adapter Proxy Bridge Flyweight Excercises Composite Decorator Decorator: Extension Method Decorator: Starbuzz Flyweight
4	Applicability Consequences of the Chain of Responsibility Example Motivation Command Objects Building Command Objects Consequences of the Command Pattern Example Motivation Applicability State machine Objects Used in Parsing Regular Expression Example Motivation Consequences of the Iterator Pattern Iterators in C# collections classes Example Interactions Between Controls Initialization of the System Mediators and Command Objects Consequences of the Mediator Pattern Single Interface Mediators Implementation Issues Example Motivation Implementation Providing Undo Command Objects in the User Interface Example	Day4.xlsx Patterns ChainOfResponsibility Command Interpreter Iterator.docx Mediator Memento Excercises ChainOfResponsibility: ATM ChainOfResponsibility: Alternative Solution Command: Single Cast Delegate Command: Multi Cast Delegate Interpreter: Product Iterator Iterator: Composite Iterator: Prime Mediator: Chat room Memento using Serialization
5	“Don’t call me, I will call you” model Consequences of the Observer Pattern Event-Handler model in .NET Example Switching Between States How the Mediator Interacts with the State Manager? Consequences of the State Pattern Example Motivation The Context The Program Commands Example Motivation Kinds of Methods in a Template Class Templates and Callbacks Summary and Consequences Example Motivation When to Use the Visitor Pattern Visiting the Classes Visiting Several Classes Catch-All Operations with Visitors Double Dispatching Issue Traversing a Series of Classes Consequences of the Visitor Pattern Example Overall structure of the design pattern catalogue Classification of relationships Categories of relationships Modifying relationships and design patterns	SDP.zip Day5.xlsx Patterns Observer State Strategy TemplateMethod Visitor Excercises Observer State Strategy Template Method Visitor: DoubleDispatching Visitor: Computer Visitor: Employee
