This addons installs a new dashboard item which allows you to access the MySQL database specified during the Concrete5 installation. Uses SQL Buddy.
Please be aware that this addon is not meant to be used by your customers. It's primarily meant to be a tool for developers to access the raw data. It allows you to break your site if not used properly!
I recommend not to assign the "Administrator" group to all "editors" of your site. I suggest you create a separate group for them and disable the access to this addon for this group. (You can display system pages in the sitemap by activating the checkbox in the right bottom corner)
