# Glossary

> Get familiar with the key terms you will encounter throughout Runway.

### **Dimension**

A data type in Runway—like numbers or dates—used to categorize data. Common examples:

* **GL dimensions**: `Class`, `Account`, `Account Type`, `Vendor`
* **HRIS dimensions**: `Role`, `Department`, `Location`
* **CRM dimensions**: `Region`, `Pipeline Stage`

**Dimension values** are the options within a dimension (e.g. `Marketing`, `Engineering`, `Sales` for the `Department` dimension).

### Driver

A time series that tracks numerical or date-based values over time. Drivers come in these types:

* **Unsegmented driver** – Typically created in a [driver table on a page](/concepts/pages/drivers-table-block) or [model](/concepts/models/models-basics) (e.g. `Burn`, `Runway`).
* **Segmented driver** – Broken down by one or more dimensions. Most often created in a database (e.g. `Amount [Account][Class]`).
  * **Segment of a driver** – A single portion of a segmented driver (e.g. `Amount [2300 — Payroll Liabilities][Engineering]`).

### Databases

Where all your structured data lives—both integration-synced and manually created.

* **Integration-created** – Pulled from [systems](/integrations/intro-to-integrations) like your GL, HRIS, or CRM.
* **User-created** – Built from scratch for modeling assumptions, rollups, or [lookups](/guides/modeling/lookups).

### Models

Tables of related drivers for lightweight modeling and grouping.

### Pages

A flexible canvas for combining drivers, charts, and data views to tell a story, report, or collaborate.

**Block** – Each content element on a page is a block, such as a [driver table](/concepts/pages/drivers-table-block), [chart](/concepts/pages/charts-block), [database](/concepts/pages/database-block), [plan timeline](/concepts/plans#surfacing-plans-in-pages), or [text, image, and video block](/concepts/pages/text-media-block).

### Section

Used to organize your pages, models, and databases in the sidebar.

[Learn more about sidebar sections →](/concepts/sidebar)

### Scenario

A version of your model. Used for simulating various scenarios, testing new ideas, and running [BvA](/guides/modeling/bva). Scenarios can stay in sync with your Main scenario or diverge completely.

[Learn more about scenarios →](/concepts/scenarios)

### Plans

Used to tag forecast overrides with real-world business context (e.g. hiring plans, initiatives, contracts). Helps bridge roadmap and financial data.

[Learn more about plans →](/concepts/plans)

### Role

Determines a user's default workspace access. See the current role list and capability matrix in [Permissions](/guides/sharing/permissions) and [Roles and access](/reference/roles-and-access).

[Learn more about roles →](/guides/sharing/permissions)

### Access level

In addition to having a role, each user can have different access levels for individual resources in Runway.
