What is event-driven architecture? Event-driven architecture (EDA) is a software design model built around the publication, capture, processing and storage of events. It enables teams to identify system events (basically any change or action that occurs within the system) and respond and react to...
Event-driven architecture (EDA) is a software design pattern used in microservices or other decoupled services or apps. Each service in the ecosystem can asynchronously publish and subscribe to events via an event broker. EDA provides a flexible, scalable, and real-time approach to processing...
What is Event-Driven Architecture?An event-driven architecture (EDA) is a modern software design approach centered around data that describes events—selection of a button on a user interface (UI), the addition of an item to an online shopping cart, notification of payment on a point of sale...
Event-driven architecture (EDA) is a software design pattern where there is a loose coupling between the various components within a system.
Event-driven design can also extend an existing application in a flexible, noninvasive manner. Rather than changing the original application to add new functionality, developers can add event producers to the original application -- for example, by processing thelog filesit produces. The additional ...
A simple example of this trap is when an event is used as a passive-aggressive command. This happens when the source system expects the recipient to carry out an action, and ought to use a command message to show that intention, but styles the message as an event instead. ...
What is domain-driven design (DDD)? Domain-driven design (DDD) is asoftware developmentphilosophy centered around the business domain, or sphere of knowledge, of that software's users. DDD emphasizes the importance of understanding and modeling the business domain for which a software application ...

Wirfs-Brock Associates Value object—An object that needn't be unique (others can share a reference to it) It typically describes some characteristic. "I don't care which blue crayon I use, just that I have one." *Described by Eric Evans in Domain Driven Design, chapter on Entities www...
systems dynamics simulation provides results over a longer term and a wider breadth by using sample, historical, or non-static inputs. When an event such as a reduction in revenue or the introduction of a new product line is introduced to the simulation, the analysis provides a wide-ranging ...
