# Dimensions

> Categorize and slice your data with descriptive attributes

Dimensions are the attributes that describe, categorize, and segment your objects. They're what you group by, filter on, and break down — region, status, product category, date, customer tier.

## How dimensions work

A dimension is a property of an object that the agent can use to slice data. When someone asks "revenue by region," the agent uses the Region dimension to group results.

| Object   | Dimension | Source column       | Description                  |
| -------- | --------- | ------------------- | ---------------------------- |
| Customer | Region    | `accounts.region`   | Geographic area              |
| Customer | Tier      | `accounts.tier`     | Gold, Silver, Bronze         |
| Order    | Status    | `orders.status`     | Pending, Complete, Cancelled |
| Order    | Date      | `orders.created_at` | When the order was placed    |

## Dimensions vs. metrics

Dimensions describe *what* you're looking at. Metrics measure *how much* or *how many*. You group by dimensions and aggregate metrics.

* "Revenue **by region**" → Region is the dimension, Revenue is the metric
* "Customer count **by tier**" → Tier is the dimension, Count is the metric
