# System / Policy Schemas

## Schema Demo

There are two types of Schemas:

1. [System Schemas](#system-schemas)
2. [Policy Schemas](#policy-schemas)

To display System / Policy Schemas in the GUI, we have added a toggle in the Schemas tab.

#### System Schemas

Whenever an account is created, System Schemas have generated automatically.

{% hint style="info" %}
Note: By default System Schemas cannot be edited/deleted.
{% endhint %}

#### Policy Schemas <a href="#policy-schemas" id="policy-schemas"></a>

This is the second option in the Schemas tab. This option displays all the Policy Schemas related to all the created/imported Policies in the Policies tab.

The below screenshot shows the Policy Schemas of an imported Policy (i.e. iRec).

We also have a filter, where by default, all the Schemas of Policies are shown. We can also select a particular Policy to show the Schemas of the selected Policy.
