# Getting Started with Cube Core

> Create a project, connect a database, query data, and add a pre-aggregation in self-hosted Cube Core.

Getting started with Cube Core

First, we'll create a new project, connect it to a database and generate a data
model from it. Then, we'll run queries using the Developer Playground and APIs.
Finally, we'll add a pre-aggregation to optimize query latency down to
milliseconds.

This guide will walk you through the following tasks:

* [Create a new project](/cube-core/getting-started/create-a-project)
* [Run queries using the Developer Playground and APIs](/cube-core/getting-started/query-data)
* [Add a pre-aggregation to optimize query performance](/cube-core/getting-started/add-a-pre-aggregation)

If you'd prefer to try Cube Cloud, then you can refer to [Getting Started using
Cube Cloud][ref-getting-started-cloud-overview] instead.
