- Natural Human Thinking - Event Storming vs Event Modeling - IT seems to mimic so much from how the human brain works. Similarities are striking. It’s just as if we were to build an artificial brain, sic. Let’s dive in: human short memory (example: you can repeat a sentence that you heard, but not yet understand it) vs processor cache human operation memory vs well operation memory (RAM) human long term memory vs disk space Let’s imagine the brain as a machine that processes information. It can learn so fast, process loads of data instantly. How it acquires information/learns - this how we should gather requirements for IT systems. So how is knowledge constructed, where is it stored and how?Human memory can be divided into 2 categories: This is semantic memory and episodic memory. Both are part of explicit (conscious, declarative) memory. Semantic memory refers to general world knowledge that we have accumulated throughout the experience - that is stored in episodic memory as a stream of events. Episodic memory can contain snapshots of images, scenes that happen one after another, it’s a book of stories with images and with no conclusions. The facts, ideas, and concepts can be derived from it, thus they build semantic memory, that might be expressed in higher-level brain language (according to some scientists).
