Metadata-driven applications
Define tables, fields, relationships, apps, and processes in Java. Manage the database schema explicitly.
Build data applications with QQQ 4.0
Java metadata. Reusable application behavior.
Define tables and processes, connect your data, and extend behavior in Java. Run an editable local app with the Next dashboard, then change the source to make it your own.
The Ecosystem
A framework and its growing ecosystem
Start with the Java framework. Component templates, managed hosting, and development tooling have separate availability and release scopes.

Capabilities to configure and extend
Reuse framework facilities while keeping application behavior explicit. Validate the exact release with your data, identity provider, and workflows.
Authentication integration
Select and configure an authentication provider. Test login, logout, session handling, and denied access.
Backend modules
Use relational, MongoDB, SQLite, file-system, S3, or REST modules. Supported operations vary by backend.
Java process steps
Compose process metadata with Java backend steps. Implement business rules and recovery behavior explicitly.
Application permissions
Configure the permission rules for your application and test them across queries, processes, and custom entry points.
Metadata-driven dashboard
Use dashboard 0.41.0 with compatible table, app, process, and widget metadata. Review the sample UI.
Audit requirements
Configure audit-related facilities and verify the events, actor context, retention, and access rules your application needs.
Application APIs
Use the selected middleware/API module and its actual contract. Automatic GraphQL generation is outside this release scope.
Reporting and export
Configure reports and supported export formats for your backend, then test representative data and access restrictions.
