# Update Database Schema Draft

A **schema** defines a collection's fields, types, and validation. Schemas support drafts, versions, and publishing. This method updates the database schema draft — only the fields you send are changed.

This method is on the **Hub** surface (`norbix.hub.database`) — call it from admin tooling or IaC.

{% hint style="info" %}
These examples assume the SDK is installed and your credentials are set as environment variables — each client reads them automatically, so the constructors below take no arguments. See [Install a Norbix SDK](/sdks-and-cli/install.md).
