Rather than a lecture sequence, this course is organized as a run of questions about databases. They start with the difference between data and information, then move through database types, database servers and the job a DBMS does.
Because the material is organized as questions, it works well as a self-test. Try answering each one in your own words before moving on, since the list is more useful as a prompt than as a set of notes.
