Object-oriented programming (OOP) is a programming paradigm centred around the concept of objects. What is a Class? For example, if you want to model a Car, you would create a Car class that might have properties like colour, make, and model, and methods (functions) like start_engine() or drive(). What is an Object? OOP Concept Object-oriented … Read more
System design involves creating the architecture of a system to meet specific requirements. Here are some common terms used in system design: Network Partition In the context of distributed databases or systems, network partitions are particularly challenging because they force the system to make trade-offs between consistency, availability, and partition tolerance, as described by the … Read more
The SOLID principles are a set of five design principles that help software developers create more maintainable, understandable, and scalable code. Let’s delve into each SOLID principle and explore how they contribute to building high-quality software. Solid Overview Each principle can be applied at different levels of software design, including classes, methods, and modules. The … Read more
Dependency Inversion Principle (DIP), Dependency Injection (DI), and Inversion of Control (IoC) are pivotal concepts in software development, shaping the architecture and flexibility of modern applications. What is a dependency? A state where one class depends on another is called dependency or coupling. Example A good design has low dependency/loosely coupling. Why is dependency bad? … Read more
Design patterns play a crucial role in enhancing code quality, maintainability, and scalability. One of the most influential collections of design patterns is the Gang of Four (GoF) patterns, encapsulated in the seminal book “Design Patterns: Elements of Reusable Object-Oriented Software.” What are Design Patterns? Design patterns are proven solutions to common problems encountered in … Read more
The flyweight design pattern provides a framework for minimizing memory usage and computational overhead by intelligently sharing common elements among objects. In this blog post, we embark on a journey to explore the principles of the Flyweight pattern, dissect its key components, and unveil its real-world applications. Join us as we delve into the intricacies … Read more
The world of software design is filled with various architectural patterns that help developers create robust and maintainable code. One such pattern that plays a crucial role in managing object behaviour is the Proxy Design Pattern. In this blog post, we’ll delve into the fundamentals of the Proxy Design Pattern, understand its purpose, and explore … Read more
The State Design Pattern is a behavioural design pattern that allows an object to alter its behaviour when its internal state changes. This pattern is particularly useful when an object transitions through different states, and its behaviour needs to change accordingly. In this blog post, we’ll explore the State Design Pattern, its components, and how … Read more
Interpreter Design Pattern is particularly powerful when dealing with complex grammatical structures or when implementing languages. In this blog post, we’ll dive into the intricacies of the Interpreter Design Pattern, exploring its definition, components, and practical applications. What? The interpreter design pattern is a behavioural design pattern that is used to define a grammatical representation … Read more
The iterator design pattern stands out as a fundamental and indispensable tool. It falls under the category of behavioural design patterns and plays a crucial role in simplifying the traversal of collections. Whether you’re a seasoned developer or a newcomer to design patterns, understanding the Iterator pattern is essential for writing clean, modular, and maintainable … Read more
