# Data model

> [!note]
> To configure Content Hub, you must either be a superuser or have the necessary permissions granted to you through [user group policies](https://doc.sitecore.com/ch/en/users/content-hub/user-group-policies.html "User group policies").

Sitecore Content Hub provides a configurable data model, which is a structured representation of the underlying database. The data model – also known as a schema – includes entity definitions such as assets, products, or projects. Each definition consists of properties, and is linked to other definitions using relations.

> [!warning]
> Modifying the schema might affect many entities, causing them to be reprocessed in an immediate [graph rebuild](https://doc.sitecore.com/ch/en/users/content-hub/schema-changes-and-inheritance.html "Schema changes and inheritance"). Regular system operations are paused during the graph rebuild, so we recommend you publish schema changes outside of standard business hours.

You can customize the schema by creating or editing [entity definitions](https://doc.sitecore.com/ch/en/users/content-hub/entity-definition.html "Entity definition"), defining [taxonomies](https://doc.sitecore.com/ch/en/users/content-hub/create-a-taxonomy.html "Create a taxonomy") and [option lists](https://doc.sitecore.com/ch/en/users/content-hub/create-an-option-list.html "Create an option list"), establishing relations between [entities](https://doc.sitecore.com/ch/en/users/content-hub/entities.html "Entities"), and so on.

> [!important]
> For performance reasons, we recommend that the number of relation definitions assigned to any single entity definition be kept below 50. We also recommend that only superusers perform schema management, to avoid potential issues.

To access the schema:

1. On the menu bar, click **Manage**:mdiCogOutline:.
2. On the **Manage** page, click **Schema**.

To navigate the list of entity definitions, use the **Next** :mdiChevronRight: and **Previous** :mdiChevronLeft: arrows. To navigate directly to a specific page, click the current page number and, in the **Go to page** drop-down interface, enter a page number and click **Go**.

To view the schema in the form of a diagram, click **Tree view** in the view selector list. In the tree view, to highlight an entity definition and all direct relations, click that definition.
