# Other installation tasks

This section discusses some other installation tasks related to your Discovery Framework installation.

- Using a different database
  The Liferay portal server uses a relational database to store configuration and state, such as portlet preferences, user permissions, system settings, and more.
- Installing Corda
  The Chart component requires the installation of Corda charting software. Endeca recommends deploying Corda Server as a servlet when using it with the Discovery Framework. If you plan to use the Chart component, make sure to download corda-<version>.zip and deploy the Corda Server servlet in that package.
- Uninstalling the Discovery Framework
  To uninstall the Discovery Framework, remove the packages and directories that you installed.
