Data

Use the Data tab to define the information the application owns and the reusable types that describe it.

ER diagram

Add entities, define fields and keys, then connect entities to express their relationships. The diagram is editable rather than a generated picture: changing a field or relation changes the project model used by other tabs.

You can start manually or generate a first schema from the Domain description. Generated entities are a starting point and can be renamed, expanded, or removed.

Types

Define reusable enums, objects, aliases, and other named shapes once, then use them in entity fields and API contracts. Usage counts show whether a type is still referenced before you remove it.

What uses this work

The Backend tab can generate CRUD endpoints from the entities. Security and Traceability include entities on their matrices. Export adds the data model to the scaffolding preview and report.
