docs(normalization): illustrate worked examples with dj.Diagram figures - #259
Merged
Conversation
Add two generated, theme-adaptive dj.Diagram figures to the normalization chapter: - Fully normalized mouse-housing schema (Mouse/Cage entities + CageAssignment/ MouseWeight event tables; CageAssignment -> Cage shown as a secondary dashed FK). - Workflow-normalized order schema (Order with dashed secondary refs to Product/ Customer, then the 1:1 Order -> Payment -> Shipment -> Delivery chain). Both make the entity-vs-event split and the workflow chain visible. Single-table examples (denormalized Mouse, Species lookup) are left without diagrams.

Adds generated
dj.Diagramfigures to the Schema Normalization chapter, so the worked examples are visible, not just code.Diagrams (both theme-adaptive, LR, from the modernized renderer)
MouseandCageas entities andCageAssignment/MouseWeightas event tables keyed by date;CageAssignment → Cagerenders as a secondary (dashed) FK, which is exactly the entity-vs-event distinction the section makes.Order(with dashed secondary refs toProduct/Customer) and the 1:1Order → Payment → Shipment → Deliverychain (thick edges), making "the FK chain is the workflow" literal.Scope
Only the multi-table examples get diagrams — a single-table case (the denormalized
Mouse, theSpecieslookup) is one box and gains nothing. If you'd like the smaller relationship examples diagrammed too (e.g. the Temporal Associations patterns), I can add them.Rendered from reconstructed schemas via the merged
dj.Diagramrenderer; SVGs validated.
