Design patterns are general repeatable solutions to common problems encountered in software design. They represent best practices and provide a way to structure and organize code to solve certain types of problems. Design patterns can speed up the development process by providing tested, proven development paradigms. Key characteristics of design…

Behavioral design patterns deal with the communication and collaboration between objects, focusing on how they interact and distribute responsibilities. There are 11 commonly recognized behavioral design patterns. Here, I’ll provide a detailed explanation and a full example for each one: 1. Chain of Responsibility Pattern: Purpose: Passes a request along a chain of handlers, each…

Structural design patterns deal with the composition of classes and objects to form larger structures, such as relationships between objects, and focus on how these structures can be used to solve specific problems. There are seven commonly recognized structural design patterns: 1. Adapter Pattern: Purpose: Allows the interface of an existing class to…

Creational design patterns focus on how objects are created, instantiated, and managed. They provide mechanisms for controlling the object creation process to ensure flexibility, efficiency, and reusability. There are five commonly recognized creational design patterns: 1. Singleton Pattern: Purpose: Ensures that a class has only one instance and provides a global point of…

What is Caching? Caching is a technique used in computer science and software development to temporarily store copies of frequently accessed or computationally expensive data in order to reduce the time or resources required to fetch the data again. The primary purpose of caching is to improve the performance and efficiency of a…

The CAP theorem, or Brewer’s theorem, states that in a distributed system, it is impossible to simultaneously achieve Consistency, Availability, and Partition tolerance, proposed by computer scientist Eric Brewer, describes the trade-offs in distributed systems. You can prioritize two of these aspects, but the third will be compromised. …

ACID is an acronym that stands for Atomicity, Consistency, Isolation, and Durability. These properties are crucial in the context of database management systems (DBMS) to ensure the reliability and integrity of transactions. Let’s explore each of these properties in more detail: Atomicity: Definition: Atomicity ensures that a transaction is treated as…

The SOLID principles are a set of five design principles for writing maintainable and scalable software. These principles were introduced by Robert C. Martin and are widely used in object-oriented programming. The SOLID acronym stands for: Single Responsibility Open/Closed Liskov Substitution Interface Segregation Dependency Inversion Single Responsibility Principle (SRP): Definition: A class should have…

Apache Kafka is a popular open-source stream processing platform that is widely used for building real-time data pipelines and event-driven applications. It was originally developed by LinkedIn and later open-sourced as an Apache project. Kafka is designed to handle high-throughput, fault-tolerant, scalable data streaming and it relies on a set…
