Convert SQLite to a Mermaid ER diagram

Create Mermaid syntax

1. Open the SQLite file.
2. Launch the ER diagram to verify entities and relationships.
3. Select Mermaid and export the schema.
4. Paste the result into a Mermaid-compatible Markdown or documentation system.

erDiagram
  CUSTOMER ||--o{ ORDER : places
  CUSTOMER {
    integer id PK
    text name
  }
  ORDER {
    integer id PK
    integer customer_id FK
  }

Benefits of text-based diagrams

Mermaid syntax can be committed to version control, reviewed as text and regenerated when the schema changes. It is useful in project READMEs, architecture documentation and technical notes where a binary diagram file would be difficult to maintain.

Understand relationship limits

The converter reads declared foreign keys. It cannot safely invent relationships based only on similar column names. If an expected edge is missing, inspect the SQLite schema and confirm that the relationship is declared with a foreign-key constraint.

Keep diagrams focused

Large databases can produce crowded diagrams. Consider documenting bounded subject areas separately—for example authentication, billing or inventory—while keeping a complete schema export for reference.
