Part 3: Making it schemafull
They say relationships are the primary key to happiness.
In which case, I'm sure you must be very happy right now, having just made tons of relationships in the last part!
In this part, we'll cover how to:
Add schema definitions to tables and fields
Add constraints and assertions
Make use of the schemafull data patterns using schemafull CRUD
Hope you're excited to learn the schemafull way, let's get started.
THE PLATFORM
Everything an application and its agents know. Five surfaces, one engine.
Database
Document, graph, vector, time-series and relational in one engine.

Agent Memory
What an agent learns, with its source and its time, in the same engine.

Cloud
Managed clusters in the regions you choose, scaled on demand.

Studio
Query, explore and design the schema from the browser.

MCP
Every model that speaks MCP reaches the database and the memory directly.

IN PRODUCTION
Trusted at scale. Samsung, Nvidia, Verizon, Tencent, and Walmart run on SurrealDB.

FROM THE TEAMS
SurrealDB gives us a foundation where we can unify semantic search, knowledge graphs, and AI-driven decision making without stitching together multiple systems. Collapsing responsibility into SurrealDB has become our default engineering posture.
