# Database Management>Database

This view allows you to view database status information. It also allows you to perform maintenance tasks such as database packing, cache management, and "undoing" previous changes to your site.

`Database Size` indicates the size in kilobytes of the Zope database file. `Database Location` indicates the path to the Zope database file.

The `Pack` button removes old versions of Zope objects, reducing the size of the Zope database. Once you pack the database you cannot retrieve old copies of objects that have been removed by the packing operation. The `days` field indicates how old objects versions must be to be removed. For example if you pack the database and specify 2 days, then you will not be able to revert to object versions older than 2 days.
