# About Query Engine

> What e6data is and how the platform is organized - the starting point before you deploy and query.

This section introduces e6data: what it is, how it works, the vocabulary used throughout the docs, and the deployment models you can choose from.

## Start here

Work through these in order if you're new to e6data:

1. [Introduction](/query) - what e6data is and why it's built the way it is.
2. [How e6data works](/query/concepts/how-query-engine-works) - the engine and request flow at a glance.
3. [Key concepts](/query/concepts/high-level-architecture) - the vocabulary you'll see throughout the docs (workspace, cluster, catalog, Compute Plane, and more).
4. [Platform components](/platform/components) - what makes up the Control Plane and Compute Plane.
5. [Deployment models](/platform/deployment-models) - Serverless vs. In Your VPC.

## Next

Once you understand the platform, set up your account in [Identity and access setup](/platform/sign-up-and-log-in), then run your first query with the [Quickstart](/get-started/quickstart).
