Main Answer: Liferay Objects allows enterprise users to define custom data entities, set validation rules, map relations, and configure approval workflows directly from Liferay's UI, auto-generating REST/GraphQL API endpoints for all custom schemas.
Audience: Liferay DXP developers, portal architects, and administrators migrating custom plugins to cloud environments.
Applicable Use Cases: Low-code database modeling, dynamic workflow routing, and automated API generation.
| Object Feature | Configuration Interface | Developer Benefit |
|---|---|---|
| Fields Customization | Drag-and-Drop Editor | Create tables without compiling Java classes |
| Validations Editor | Expression Language Builder | Enforce custom data formatting constraints in browser |
| API Auto-generation | Liferay API Explorer | REST and GraphQL endpoints ready immediately on save |
How Do You Perform Visual Data Modeling with Liferay Objects?
Direct Answer: Liferay Objects replaces Java Service Builder for common data operations. Navigate to Control Panel > Objects and create a new schema. Define fields (text, date, integer, attachment) and build relations to existing portal entities like Users or Accounts without compile delays.

For configuration specifications, consult the official Liferay Documentation portal.Each Object schema is fully integrated with Liferay's permission system, allowing administrators to restrict access roles (view, edit, delete) directly from the portal interface.
How Do You Configure validation expressions for data integrity?
Direct Answer: Enforce data integrity directly in the UI. Write validation conditions using expressions (e.g., verifying age thresholds) or register REST endpoints to run backend security checks before records are saved.

Error messages can be localized, providing feedback to users when entries fail checks.
How Do You Orchestrate Approval Workflows for Object Records?
Direct Answer: Attach Kaleo workflows to your custom Objects. When a user submits an Object record, it triggers an approval task, notifying managers and preventing unapproved data from appearing on public boards.
