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!...

This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

The final project is very complex in the installation process. But once that is finished the SQL questions are simple. The course was properly paced and well structured.

The course explains essentials of SQL well but practice assignments should be placed after every video containing some new SQL syntax to consolidate acquiring knowledge.

Great course for SQL, still pretty beginner level, but would recommend some previous SQL experience here as the section on joins and sub-queries is a little challenging.

The vedio information is simple and doesn't include a lot of code practice. However, the quiz and the assignment is harder than the information mentioned in the vedio.

Very nice training videos. The assessment in the end was a bit far from the training but maybe it is also the question of knowing the data and practice of assessments.

Video's were very helpful and well organised. The end assignment however was badly phrased and overall confusing. Therefore it took way longer than the stated 2 hours.

The course is interactive and apt for beginners. The pace is perfect. The flow of the course and the way to guide us to the right answers in the quiz could be better.

Sadie did a great job with explain SQL concepts. Only thing I didnt like was peer review assignment for which I had to beg people to review mine to get mine graded.

This course is extremely helpful,4 start for that.Only if it had assignments along with the sample data to measure the range of our learning will be much helpful.

This course was good but I found at times the words being said didn't match the text in the video. It would have been more helpful "practice as you go" as well.

Good course, good explanations. The code example could have been more useful, simply displaying examples of output of each code snippet would have helped a lot.

Lectures build at a slow, comfortable pace, but be prepared to discuss things on the message board, and read classmates' comments, or the quizzes will rock you.

The project required deeper understanding than what was taught in the course and a few minor details were missed while teaching how to apply different syntaxes

Really did help me understand SQL better. The main issue I had was with the final assignment, since the tool provided to analyze the dataset was very limited.

I wish there were more practice exercises in between the videos. It would also be more helpful if there were more visuals/animations to accompany the lessons.

Although the course was very hands-on, and the Instructor made everything clear I was left wanting some more reading material for learning about Data Science

Great course, provided a really good introduction. However they course could have provided some more examples as to how to actually use the functions taught.

More exercise will be much better. For now, it is not enough for the learner to apply their skills learned in this course so they cannot master their skills.

Overall content is good. But for the beginner who has no background, it would be more helpful to show the result of coding on each statement while teaching.

Great for begginers, I'd suggest to learn with W3 school sql tutorial in parallel as it has more concrete examples and functions you can try by yourself.

great course and really liked the instructor

the assignments made me think and re-visit material, but instructions were clear and the problems a good level

Some final exam questions needed to be clarified. Also, for some reason, 0s were converted to 9s when I cut and pasted answers for the final (question 6)

Great learning SQL basics. I took away a star because some of the later concepts like CASE were not well explained and I had to consult outside sources
