Due to the advanced material, Module 12 provides Lesson 6 as honors with problems, quiz, assignment, and self evaluation. Module 12 covers four somewhat independent topics (outer joins, nested queries, membership exceptions, and containment exceptions) so learners can study these topics separately. These specialized problem areas, more difficult than combining tables with joins, provide important value to organizations when occurring in practice. To aid learners, Module 12 provides unique pedagogy with two problem-solving aids, text patterns to recognize elements of in problem statements and statement patterns to write template SELECT statements as an initial step to a complete SELECT statement. Lesson 5 provides a convenient summary of the text and statement patterns to provide learners a platform for the practice problems and assignment.

Reviews

Excellent course giving me the opportunity to review, deepen and extend my database knowledges. My peer-graded experience was very poor, the worst so far on Coursera. The grades were often arbritary.

Very good. The structure is pretty nice, it provides all the basic knowledge you would need about database management and both videos and slides are easy to understand.

Fair enough. Good material and content for someone new or that needs to remember basic concepts about databases. Not needed if the main focus is DWH and experience with DB exists

Of all the database courses I have ever done, this one covers the concepts best and exhaustively. I highly recommend it to all beginners and advanced users who want to review the basics.

Very good course. Clarified some basic concepts, got some hands on experience on using databases, ERD drawing tools. Need a bit more detailed explanation for the topics.
