Good course, helpful to understand SQL analytic functions and usage of materialized views. Explanations on big data and data governance are just a brief introduction. The assignments are rather simple to complete.

The first three weeks were a complete bore. Very slow and only query writing was the fun part. Week 4 and 5 picked up the pace though. Saved the course.

Theres too much of query running and explanation in the videos and not enough content is covered.

Enjoyable course - Professor Mannino has an excellent vision for periodically reviewing, repeating, then extending to new concepts, which is the right way to build skill. This course features subtotals and analytic functions in SQL, and query rewriting using materialized views. I am now at the point I have a lot of confidence with Oracle 12c and query capability. The problems are the right balance of meaningful challenge and skill building while still being able to complete them on evenings and weekends. In addition, the course delivers an understanding of context, technologies and platforms from which BI is created with trade-offs and policy important to commercial enterprise.
