Turning a vague idea, like a database to manage gym instructor schedules, into a properly structured set of tables is a skill most developers pick up by trial and error. Alexey Makhotkin's book teaches it as a repeatable process instead.
From Idea to Structure
You start by building a structured list of anchors, attributes, and relationships, the foundation for a database that actually matches what the business needs. Each requirement gets described as a clear, formalized statement so the purpose of every table and field stays unambiguous.
Logical to Physical
The final stretch walks through turning that logical model into a physical one, using a consistent, tested method so the transition from concept to a real, working database stays straightforward.
