What is ESB?

An Enterprise Service Bus (ESB) is fundamentally a software architecture. It gives a communication system between mutually interacting software applications in a service-oriented architecture. It removes the point-to-point integration and integrates numerous applications together over a bus-like infrastructure. It will handle transforming and routing the messages according to their appropriate destinations.

Getting Started with Maven

Since Ant, Maven, and Gradle are dominated in the JVM ecosystem as  Java build automation tools, you may be familiar with Maven If you have ever worked on a Java Project.

Let’s explore how these Java build automation tools evolved in the JVM ecosystem.

• Apache Ant (“Another Neat Tool”) is a Java library which is used to automate the build processes for Java applications. Other than that it can be used for building non-Java applications.
• Apache Maven is a build automation tool and also a dependency management tool. It is primarily used for Java applications. Maven also uses XML files the same as Apache Ant but in a much more manageable way.
• Gradle is a dependency management and a build automation tool which was built upon the concepts of Ant and Maven.

In this article, I am going to discuss Maven as a dependency management tool.

Fundamental of React

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called “components”.  Followings are some fundamentals that you need to know when you work on React.

An Introduction to React using Flux Architecture

Flux is developed by Facebook as an application architecture for UI  implementation. React is a JavaScript library which is used to build user interfaces.  So Facebook use Flux architecture when they implementing user interfaces with React.

Applications which are implemented in React using flux architecture have four major parts. These are independent nodes with distinct inputs and outputs.

•    Actions
•    Dispatcher
•    Stores        
•  Controller Views

What is Natural Language Processing and how does it works ?

In 1950 Alan Mathison Turing (often called as the father of modern computing) published his famous paper titled “Computing Machinery and Intelligence”. That was a seminal paper on the topic of artificial intelligence. In here Alan introduced a game called "The Imitation Game” and he proposed a variation of this game that involves the computer.

Then Alan Turing expressed an opinion that if a machine could have a conversation with a human and trick the human into thinking the machine was a person itself, then it was artificially intelligent. That was named as Turing test and became the first step to the birth of artificial intelligence.
