Some students learn most by being teached/shown by someone else, others prefer written material/transcripts, and others to try out things themselves. There is so much documentation/guides/... online that I think especially for a database course it would make sense to provide students with pointers on how to play around with a database/dataset at home. Tasks like "optimize xy as best as you can, for pointers see here, here, here" can really spur a student's ambition. You could probably also arrange your "live sessions" around those (extra? -- you didn't mention if students have to do mandatory homework for your course) assignments.
