This course offers a focused exploration of design patterns, crucial tools for software developers to create reusable, scalable, and maintainable code.

We begin by examining the rationale behind design patterns, situating them within the broader context of software engineering principles.

Students will learn about the 'Gang of Four' (GoF) patterns, which are categorized into three groups: Creational, Structural, and Behavioral.

Each category is explored through its most commonly used patterns like Singleton, Adapter, Observer, etc.

The course is structured to provide not just theoretical understanding but also practical applications. Students will engage with real-world scenarios where design patterns offer elegant solutions.

Special attention is given to the subtleties of implementing these patterns.

Further, the course will address concurrency patterns, vital for modern multi-threaded applications, and architectural patterns, which play a critical role in the development of large-scale systems.

• Session 1 : This Session Aims To Establish A Comprehensive Understanding Of What Design Patterns Are, Their Historical Context, And Their Significance In Software Development.

• Session 2 : This Session Focuses On Creational Patterns, One Of The Three Categories Of The 'Gang Of Four' Design Patterns. This Session Delves Into The Specifics Of How Creational Patterns Facilitate Object Creation In Software Development, Making The Creation Process More Adaptable And Dynamic.

• Session 3 : This Session Introduces Structural Patterns, Focusing On How These Patterns Help In Composing Classes Or Objects To Form Larger Structures. Students Will Explore Patterns Like Adapter, Composite, Proxy, Flyweight, Facade, Bridge, And Decorator, Understanding How They Facilitate Building Efficient And Scalable Software Architectures.

• Session 4 : This Session Deals With Effective Communication And Responsibility Delegation Between Objects. Key Patterns Such As Strategy, Observer, Command, Iterator, Template Method, State, Chain Of Responsibility, Mediator, And Memento Are Covered, Highlighting Their Roles In Facilitating Robust And Flexible Interactions Within Software Applications.

• Session 5 : This Session Covers Patterns Like Thread Pool, Worker Thread, And Asynchronous Completion Token, Emphasizing Their Importance In Managing Concurrent Processes And Threads Efficiently In Software Development.

• Session 6 : This Session Explores Architectural Patterns, Providing Insights Into High-Level Structural Organization Of Software Systems. Students Will Examine Patterns Like Mvc, Mvp, Mvvm, And Microservices Architecture, Learning How They Influence The Overall Design And Functionality Of Complex Software Systems
