 Database Activity in Moodle 3.0 There are two improvements to the database activity. When creating a new database and setting the entries to require approval, unapproved entries are now highlighted for the teacher and the user who added the entry. It's also possible to prevent database entries from being edited once they've been approved. We're in the database setup screen of a new database activity and in the entries section we'll set approval required to yes and allow editing of approved entries to no. Once the database activity is available and students have added entries to it, when we log in as a teacher we can easily see unapproved entries highlighted in red, in single view or in list view. If we approve an entry the highlighting disappears.
