Designing a Parking Lot System involves the use of various design patterns to structure the system in a way that is flexible, scalable, and easy to maintain. In this case, the Parking Lot System is built to manage parking spots, vehicles, parking tickets, and payment modes. Requirment 1 Solution Identify key objects/classes in the system. … Read more
Class Diagram is widely used in object-oriented programming to visualize and design the structure of software systems before writing any code. What is a Class Diagram? A Class Diagram is a type of static structure diagram in the Unified Modeling Language (UML) that describes the structure of a system by showing its classes, attributes, methods, … Read more
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 Class A is dependent on Class B, i.e. Class A has to create … Read more
Design patterns are crucial 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 software design. … Read more
