24. WHAT IS AN EVENT? Event [ih-vent] (dictionary.com) • something that happens or is regarded as happening; an occurrence, especially one of some importance • something that occurs in a certain place during a particular interval of time • the outcome, issue or result of anything @gunnargrosch
25. WHAT IS AN EVENT? • Events are facts: The image was uploaded • Events are temporal: The image was uploaded 2019-10-16 18:34:21 • Events are immutable: The image was uploaded 2019-10-16 18:34:21 – no matter what you do afterwards @gunnargrosch
