What it does
Directus introspects database schemas and provides REST/GraphQL APIs and a data studio. It layers permissions and application features over supported databases.
Why it’s interesting
Schema introspection and access-control synthesis make a useful backend study. Directus uses a source-available license with terms that differ from OSI-approved open source; check terms for your use.
Real-world use case
Give an internal team an admin interface over a staging SQL database.
What I can learn
- 01
Database metadata introspection
Study how database catalogs reveal tables, columns, and relations that the application can expose without replacing the schema.
- 02
Runtime REST and GraphQL schema generation
Follow how inspected fields and relationships become REST endpoints and GraphQL types at runtime.
- 03
Row- and field-level permissions
Understand how permissions restrict which records a role sees and which fields it can read or change.
One thing to explore
Database introspection and services
Follow the api/src/database implementation and connect it to the concepts above.

Inspect the admin setup
Before you start: Docker and a local test database; do not use real production data in a demo.
- Read the current license and local installation guide.
- Start a disposable local instance following the official quickstart.
- Create a test collection and inspect its generated API route.
