๐๏ธ Mastering Architectural Design Patterns: Building Robust Software Architectures
๐ What is a Design Pattern?
A design pattern is a tried and tested solution to a common problem in a specific context. They serve as templates to guide software development, making the process more efficient and standardized.
๐ ๏ธ Example: MVC (Model-View-Controller) Architecture
The MVC architecture is a popular design pattern that separates an application into three interconnected components:
Model: Manages data and business logic.
View: Handles the display and presentation.
Controller: Acts as an interface between Model and View, processing user input.
๐๏ธ Categories of Design Patterns
Design patterns are broadly categorized into several types. Here, we'll focus on two main categories:
๐๏ธ Creational Design Patterns
Creational design patterns deal with object creation mechanisms, optimizing the process of object instantiation.
Singleton Design Pattern
- Ensures that a class has only one instance and provides a global point of access to it.
๐ญ Factory Design Pattern
The Factory design pattern is responsible for creating instances of various classes based on input parameters. This pattern abstracts the instantiation process and allows for the creation of objects without specifying the exact class of object that will be created.
Key Features:
Produces objects of the same type.
Typically takes a string input to determine which object to create.
๐ Why Use Design Patterns?
Reusability: Patterns provide a reusable solution to common problems.
Efficiency: They streamline the design process, saving time and effort.
Maintainability: Using standard patterns makes code easier to understand and maintain.
Scalability: Patterns help in building scalable and flexible software architectures.
