A Datab Node is the institution's own computer. It boots its own operating system, runs its own database, serves its own clients on the local network, and survives the internet going down. When the internet is up, the node syncs to other nodes and to head-quarters services. When the internet is down, work continues.

What ships on the node

• Ubuntu Core appliance image with the Datab Node services bundled.
• PostgreSQL 16 + Flyway-managed schema.
• Micronaut backend serving DatabStudio Finance, School, and Health launch modules on the LAN.
• Atlas Core for identity verification, trust, consent, and audit-linked records.
• Ollama for local AI inference.
• Orula and Gu agents (preview) for bounded intelligence and security.

What does not ship on the node

• No internet-only services. Every required workflow has an offline path.
• No vendor lock-in. The data is the institution's; export is built in.
