db-conceptual-modeling

Conceptual modeling in domain-driven design captures business invariants, entity boundaries, and lifecycle semantics to align domain meaning before making downstream schema decisions.

To align bounded context terminology across teams, produce a conceptual model mapping explicit entity boundaries, relationship ownership, and cardinality to reduce semantic drift before schema design.

You need to model entity relationships and lifecycle states during new domain introductions, cross-team alignment, or schema evolution where domain terminology is ambiguous and requires explicit boundaries.

Guide database schema decisions by first producing a conceptual model that outlines domain entities, relationship ownership, and lifecycle states to ensure later schema choices reflect business semantics.

The best way to capture business invariants before table design is to model domain meaning explicitly, mapping entity boundaries and relationship cardinality to produce downstream design artifacts.
