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 database systems. This course is designed to give you a primer in the fundamentals of SQL and working with data so that you can begin analyzing it for data science purposes. You will begin to ask the right questions and come up with good answers to deliver valuable insights for your organization. This course starts with the basics and assumes you do not have any knowledge or skills in SQL. It will build on that foundation and gradually have you write both simple and complex queries to help you select data from tables. You'll start to work with different types of data like strings and numbers and discuss methods to filter and pare down your results. You will create new tables and be able to move data into them. You will learn common operators and how to combine the data. You will use case statements and concepts like data governance and profiling. You will discuss topics on data, and practice using real-world programming assignments. You will interpret the structure, meaning, and relationships in source data and use SQL as a professional to shape your data for targeted analysis purposes. Although we do not have any specific prerequisites or software requirements to take this course, a simple text editor is recommended for the final project. So what are you waiting for? This is your first step in landing a job in the best occupation in the US and soon the world!...

Excellent course for basic SQL knowledge. However, the tests and final assignment are not that easy as taught in the lessons. Highly recommend!

The questions in the final assignment were quite difficult to understand and the overall course took longer than the estimated amount of hours.

The course should have also provided an opportunity of code along with the videos. And output of all the the codes in the video is not shown.

The course was a great introduction to SQL and the peer reviewing process is a great initiative. The course was well paced and well designed.

If you are a beginner in SQL topics, take this course. But if you already have the basics, you should look for other more advanced projects.

Worth doing. Perhaps i missed more elaborate query examples and devote more time to the creation and reading of other (external) databases.

I think videos should have more information, as some questions are such that finding answers is not straight forward.

But very good course!

Somethings are worded strange and difficult to understand what is being asked of, but ultimately gives you a good starting point into SQL.

The final assignment, at certain parts is not very clear maybe it's time to update it based on review and repeated question from the forum

Bon cours dans l'ensemble. Bonne structure et plutôt pédagogique, mais le test final est un peu compliqué par rapport au matériel couvert.

Overall good, the questions in the assessment were confusing at some points. I would look at editing those to be more specific to the ask.

The peer review performed by other students is careless. All the activities must be automatically evaluated or reviewed by an instructor.

Overall a great course, however the dataset provided for the final Peer-graded assignment was incomplete which cause me some frustration.

Was well prepared and thorough review. Would have liked to see more on cleansing data. Final exam felt it was to open to intrepretation.

Nice introduction. Peer review assignment is a good idea. I would appreciate if the logic behind queries are explained with more detail.

Great lesson even for totally newcomers. Though quizzes are sometimes tricky and have little differences in the things you get taught.

Nice course with good pacing. Though it is a bit simple and going through other functions like window function will be really useful.

Excellent course for beginners, however, the examples could be more detailed as in the latest weeks it was sometimes hard to follow.

everything else was good but last assignment has some poor worded Q's and in-browser engine has known issues that haven't been fixed

solid fundamentals course, although the peer reviewed project needs some clarity around the final 3 questions. wording is too vague
