Reading Time: 4 minutes Introduction A few years ago Reactive Programming was introduced as an improvement upon the imperative programming paradigm. It provides some important advantages over the imperative way by relying on asynchronous programming. These days we see a lot of enterprise applications use the reactive way but still, there are ones using the imperative approach. In this blog, we will try to explore what are the differences Continue Reading

SOLID Principles: Open Closed Principle for better Understanding of extension and modification.

September 27, 2022October 25, 2022Architecture, Javasolid principles

Reading Time: 5 minutes Introduction The Open-Closed Principle states that a software module (class, method, etc.) should be open for extension but closed to modification. This principle was proposed by Bertrand Meyer in the late 1970s and early 1980s. As a guideline for designing object-oriented software. The OCP states that the purpose of design patterns is to hide details from clients. And can focus on their specific problem domain Continue Reading

Reactive System: A Better Architecture for Modern Software

April 19, 2022April 19, 2022Reactive ArchitectureReactive Manifesto

Reading Time: 3 minutes Today, most real-time software are built as a reactive system. However, they have evolved over time. A few years back, software were way different from what they are today. They were different not only in terms of features and functionalities they offer but also in the way they were designed. For instance, earlier software dealt with limited data which was mostly at rest- meaning it Continue Reading
