Tutorial: Why is event-driven thinking different from traditional thinking about computing?

Abstract

We observed that many of the applications that are event-based by nature are designed and developed using the conventional thinking about programming, and do not employ event based thinking. The developers are doing a kind of event processing without acknowledging it. One of the main reasons is the fundamental thought differences between event-driven thinking and the design of traditional request-driven applications. This tutorial concentrates on the thought process and the modeling aspects. It starts with the ontology and semantics of the term events, continues with the inter-relationships among events and other entities (processes, decisions, objects, actors), and discusses the pragmatics of modeling of event-driven logic within a computational independent model.
