#event-sourcing

A football scoreboard with no state of its own. Put the pointer on any event and the board is worked out from the ones before it.

After four to six months of work, my video introducing Event Sourcing using football as a metaphor is finally out.

Semantic Diffusion describes how terms lose their meaning as they spread. I discovered it a while ago. I think Event Sourcing, CQRS, and DDD are topics that suffer from this exact problem.

Shawn McCool discusses Event Sourcing as a modelling technique—how it differs from Event Streaming, why aggregates work better as short-lived lifecycles, and how CQRS pairs naturally with it. Touches on DDD as a pursuit of domain understanding.
