About the Course

As data collection has increased exponentially, so has the need for people skilled at using and interacting with data; to be able to think critically,
and provide insights to make better decisions and optimize their businesses. This is a data scientist, “part mathematician, part computer
scientist, and part trend spotter” (SAS Institute, Inc.). According to Glassdoor, being a data scientist is the best job in America; with a median
base salary of $110,000 and thousands of job openings at a time. The skills necessary to be a good data scientist include being able to retrieve
and work with data, and to do that you need to be well versed in SQL, the standard language for communicating with databa...

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

I loved the practices. I learned alot But I think some of them had mistakes... The online visual studio code never worked for me! It might be good to make a video that explains how to work with it.

This course is a basic introduction to SQL, using SQLite. It covers the logic of databases, ER diagrams, how to select data from a table, create new variables, use aggregate functions, join tables and use date and text features. I finished the course with a basic set of SQL skills. That is the upside of this course.

The downsides are many. The lectures are dull and uninspired. The teacher is inarticulate and does a poor job of explaining the concepts. Some of the homework problems require the use of features not covered in class. Some of the instructions in the homework assignments are unclear, leaving the student wondering what is being asked of them. Some of the code used in the lectures does not work in the homework assignments, particularly the date functions. Week 4 of the course was particularly poor, and it was an endurance test to complete it. The final assignment, which is supposed to take 1 hour, took over a day, in part because the poor directions provided. On more than one question, I was not sure what the instructor was looking for.

The final downside is Coursera itself--the discussion boards are a useless mess. They are full of people begging other students to grade their assignments, with little actual discussion of the course material. If you are looking for help understanding something, look elsewhere; you will not find it in the discussion boards. Coursera needs to fix this mess.

In short, I can't understand how this course has an average rating of 4.5. I would not recommend it. There have to be better introductory SQL courses out there.
