== Using Cypher on Aura

Most Cypher features are available on all tiers of Aura.
There are, however, some features which are not available to Aura instances.
Most Cypher features are available across all tiers of Aura.
However, certain features are not supported in Aura instances.
For example, it is not possible to create, alter, or drop databases using Aura, nor is it possible to alter or drop servers.

There are also certain Cypher features which are only available on AuraDB Enterprise instances.
These can be categorized as the role-based access-control features of Cypher.
For example, it is not possible to create, alter, or drop roles using AuraDB Free, AuraDB Pro, AuraDS Pro, or AuraDS Enterprise, but it is possible using AuraDB Enterprise.

The Cypher Manual uses two different labels to differentiate this distinction:

[options="header,cols=""2a,2a"]
|===
| Label | Description
| label:not-on-aura[Not Available on Aura] | Cypher feature not available on any tier of Aura.
| label:aura-db-enterprise[AuraDB Enterprise] | Cypher feature only available on AuraDB Enterprise.
|===
Additionally, some Cypher features are exclusive to AuraDB Business Critical and AuraDB Virtual Dedicated Cloud tiers.
These primarily fall under database administration and role-based access control capabilities.
