Nice couse on the big picture. Dr. Chuck did it again, nice teaching.
After doing this course you feel a little "wiser", because you learn about many things related to data management and I think that it's a good starting point in this matter; but I have to say that this one has been the less rewarding course of the especialization to me, because you rarely have to code or think solutions, you just have to tweak a bit the code given by dr. chuck (more complex than in the previous courses).
It's still a higly recommendable course.
Manuel J. Barbero completed this course, spending 4 hours a week on it and found the course difficulty to be medium.
