= Connecting to a database

Deploy and connect a MongoDB database where the `national-parks-app` application stores location information.
Once you mark the `national-parks-app` application as a backend for the map visualization tool, `parksmap` deployment uses the {product-title} discover mechanism to display the map automatically.

.Prerequisites

* You must have access to an {product-title} cluster.
* You must have installed the OpenShift CLI (`oc`).
* You have a deployed image.

.Procedure

* To connect to a database, enter the following command:
+
[source,terminal]
