What is Event-Driven Architecture (EDA)?

Definition and meaning of Event-Driven Architecture

Event-driven structure (EDA) is a Software structure sample that promotes the production, detection and consumption of, and reaction to, enormous cHanges in a sySTEM’s State (referred to as activities). This is implemented through the design and Implementation of applications and systems that transmit occasions among loosely coupled software additives and offerings.

What Does Event-Driven Architecture Mean?

Event-driven architecture compliments service-oriented structure because those offerings may be activated by way of triggers fired on incoming activities. Event-driven structures include event emitters and occasion consumers. Event Clients observe reactions as quickly as occasions are supplied.

1. Header: Includes facts such as event name, occasion time stamp and occasion kind
2. Body: Describes what absolutely happened

• Event generator
• Event channel
• Event processing Engine
• Downstream event-pushed pastime

The three kinds of event processing are:

• Simple event processing
• Event flow processing
• Complex Event Processing

What does EDA stand for?

This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, EDA stands for Event-Driven Architecture.
