LLD : Low Level Design
What is Proxy design Pattern? The Proxy Design Pattern is a structural design pattern that allows an object to act as an interface to another object. It is commonly used to control access to an object, delay the full cost of its creation and initialization until it is actually used, or provide a placeholder for […]

What is abstract factory pattern? It is a creational design pattern which works on top of the factory pattern. In this case, the client uses abstract factory to create factories that in turn create specific groups of products. When to use Abstract Factory pattern? The Abstract Factory pattern is particularly useful in scenarios where a

What is Factory pattern? It is a very commonly used creational design pattern. Following diagram shows it’s implementation: When is Factory pattern used? The Factory Pattern is typically used in situations where a system needs to manage, create, and represent multiple types or classes of objects that share a common base class or interface. This

What is decorator pattern? The decorator pattern is a structural design pattern that allows behaviour to be added to individual objects, either statically or dynamically, without affecting the behaviour of other objects from the same class. Here is a diagram to show the decorator pattern. When is decorator pattern used? This pattern is particularly useful

What is observer pattern Following is a diagram that shows how an observer pattern looks like: When is observer pattern used? The Observer pattern is typically used in scenarios where a change in one object’s (also called a subject) state needs to be notified to one or more other objects (also called observers) and possibly

What is Strategy pattern? Following is a diagram that captures how a strategy pattern looks like:\ When to use Strategy Pattern? The strategy pattern is a design pattern in software engineering that enables an object to change its behavior dynamically by switching out parts of its algorithm at runtime. It’s particularly useful in scenarios where
