# Step 16: Install ArcGIS Data Store
**You will continue to use the AD service account to install the ArcGIS Data Store.**
**Once the ArcGIS Data Store is installed, it will either open up at** [**https://localhost:2443/arcgis/datastore**](https://localhost:2443/arcgis/datastore)**or you can navigate there manually:** [**https://localhost:2443/arcgis/datastore**](https://localhost:2443/arcgis/datastore)**.**
**The ArcGIS Data Store will be configured with the ArcGIS Server credentials, and will create a Relational for Hosted Services and a Tile Cache database.**
**Once the ArcGIS Data Store is installed, log in to the ArcGIS Server manager to ensure that the ArcGIS Data Store is completely valid. This is important for Federation.**
## **Federation:**
**To complete the configuration process, you must now federate the ArcGIS Server site with your Portal and set it as the hosting server. Please sign in to your Portal as an administrator and navigate to My Organization > Edit Settings > Servers. Use the Add Server option to federate the site. Then set the site as the hosting server and click Save.**
**Then make that server your Hosting Server because that is where you installed the ArcGIS Data Store.**
**You will now see your Federated ArcGIS Enterprise.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://arcgis-enterprise-jumpstart.geomarvel.com/step-16-install-arcgis-data-store.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
