Commonly Used Design Patterns
In Object-Oriented Analysis and Design (OOAD), several design patterns are commonly used to address recurring design problems. Here are some of the most commonly used design patterns:
Ensures that a class has only one instance and provides a global point of access to it. Useful for managing global resources or maintaining a single configuration throughout an application.
Defines an interface for creating an object, but allows subclasses to alter the type of objects that will be created. Useful for decoupling the creation of objects from the client code.
Provides an interface for creating families of related or dependent objects without specifying their concrete classes. Useful for creating objects with varying implementations but ensuring they work together seamlessly.
Separates the construction of a complex object from its representation, allowing the same construction process to create different representations. Useful for creating objects with a large number of configuration options or parameters.
Creates new objects by copying an existing object, known as the prototype, rather than creating new instances from scratch. Useful for improving performance and reducing the overhead of object creation.
Allows incompatible interfaces to work together by providing a wrapper or intermediary that converts the interface of one class into another interface expected by the client. Useful for integrating legacy code or third-party libraries into new systems.
Defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Useful for implementing event handling systems or maintaining consistency between related objects.
Defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows the algorithm to vary independently from the clients that use it. Useful for selecting algorithms at runtime or providing different implementations of the same behavior.
These design patterns provide solutions to common design problems encountered during software development and promote principles such as code reuse, modularity, and flexibility in OOAD.
Patterns and Frameworks in OOAD
Patterns and Frameworks in Object-Oriented Analysis and Design (OOAD) are like building blocks for making strong and reliable software. This article delves at, exploring important patterns and frameworks that help make software development easier and faster. We talk about both the classic design patterns and newer frameworks that help organize software better. Understanding these patterns and frameworks helps developers create software that can handle complexity, predict problems, and last a long time without getting outdated.
