DB Conceptual Modeling

Overview

Use this skill to model domain meaning first, so later schema decisions reflect business semantics rather than accidental implementation details.

Scope Boundaries

• Teams disagree on entity meaning or relationship semantics.
• A new domain area is being introduced.
• Existing schema complexity suggests conceptual drift.

Core Judgments

• Entity versus value concept boundaries.
• Cardinality and ownership semantics of relationships.
• Lifecycle states and temporal meaning.
• Bounded-context boundaries and shared concepts.
