Patterns in Software Development
6 videos • 1,674 views • by Build with Akshit Patterns in software development are reusable solutions to common problems or challenges that developers encounter when designing and building software systems. Here are some well-known software patterns, including the ones you mentioned: 1. **Pub-Sub Model (Publisher-Subscriber)**: - **Description**: This behavioral pattern involves the communication between multiple parties where senders (publishers) of messages do not need to know the receivers (subscribers) explicitly. - **Use Cases**: Event-driven architectures, messaging systems, real-time updates. 2. **Client-Server Model**: - **Description**: This architectural pattern involves a division of labor between two types of software components: clients, which request services or resources, and servers, which provide those services or resources. - **Use Cases**: Web applications, cloud computing, networked systems. 3. **MVC (Model-View-Controller)**: - **Description**: This architectural pattern separates an application into three interconnected components: the Model (data and logic), the View (presentation and user interface), and the Controller (handles user input). - **Use Cases**: Web applications, desktop applications, GUI-based software. 4. **Singleton Pattern**: - **Description**: This creational pattern ensures that a class has only one instance and provides a global point of access to that instance. - **Use Cases**: Logging, database connections, caching. 5. **Factory Method Pattern**: - **Description**: This creational pattern defines an interface for creating an object but lets subclasses alter the type of objects that will be created. - **Use Cases**: Frameworks, libraries, extensible systems. 6. **Observer Pattern**: - **Description**: This behavioral pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents (observers) are notified and updated automatically. - **Use Cases**: Event handling, UI components, distributed systems. 7. **Strategy Pattern**: - **Description**: This behavioral pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It lets the algorithm vary independently from clients that use it. - **Use Cases**: Sorting algorithms, encryption methods, payment processing. 8. **Decorator Pattern**: - **Description**: This structural pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class. - **Use Cases**: Extending functionality, adding features to objects, UI customization. 9. **Adapter Pattern**: - **Description**: This structural pattern allows the interface of an existing class to be used as another interface. It is often used to make existing classes work with others without modifying their source code. - **Use Cases**: Integrating legacy systems, third-party libraries, and interfaces. 10. **Command Pattern**: - **Description**: This behavioral pattern encapsulates a request as an object, thereby allowing for parameterization of clients with queues, requests, and operations. - **Use Cases**: Undo/redo functionality, queues and task scheduling. These patterns represent solutions to recurring design and architectural challenges in software development. Understanding and applying these patterns can lead to more maintainable, flexible, and scalable software systems.
