Design backend data models visually.

Define entities, fields, keys, and relationships on a visual canvas. Validate your backend data model, track revisions, and share it with your team.

AvoraOrders workspace
Data model

An order management diagram: one Customer has many Orders, and each Order contains many OrderItems. Order status uses the OrderStatus enum.

Customer, Order, and OrderItem entities highlighted.

A shared model.
Room to evolve.

Keep your team’s changes, decisions, and milestones in the same workspace.

Version control built in.

Track changes, compare revisions, and restore a stable state without losing momentum.

Build together in realtime.

Work in one shared backend workspace with changes and decisions visible to the whole team.

Define fields, keys,
and relationships.

The types, relationships, and constraints your backend needs, defined together in one visual model.

Fields & enums

Flexible field types
Define fields with primitive types, dates, UUIDs, JSON, files, and lists to match your application’s data.
Reusable enums
Define shared values once and reuse them across entities, keeping statuses, roles, and other fixed choices consistent.

Relationships

Relationship types
Capture entity connections and ownership with support for association, aggregation, composition, inheritance, realization, and dependency.
Cardinality & foreign keys
Define one-to-one through many-to-many relationships, allow optional links, and control which entity holds the foreign key.
Inheritance & polymorphism
Reuse shared fields through parent models and extend them with specialized types, without duplicating the common structure.
Self-referencing relationships
Model trees, nested categories, and threaded comments with relationships that connect an entity to itself.

Rules & validation

Field constraints
Set primary keys, required and unique fields, indexes, defaults, and custom validation to define valid data at the model level.
Validate as you design
Catch duplicate fields, unknown types, and invalid keys in the workspace, before they become implementation issues.
