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!...

The course is simple and clear for a beginner. The slides,video and notes are helpful and it guides me slowly to understand different SQL syntax and its applications. The quiz and assignment are really good platform to practice all the knowledge i learnt from those 4 courses. Lovely! Highly recommend to others who never learn SQL before.

Some of the beginning is a little too easy. The last assignment of week 4 was much more time consuing than anything else - expect to take 5+ hours if you're going to do a fantastic job. You could probably rush through it in less than 2 hours but as a peer grader, I could tell who rushed through, and who took time to do a fantastic job.

The course provides a lot of useful material and additional resources. The lessons are clear and interesting and help the students stay on track and keep learning. With a considerable amount of time practicing what I've learned during lessons, I think I have understood the underlying principles of SQL which I can use in the future.

The course was well explained. I struggled a bit with some topics like combining multiple joins and subqueries. A few additional examples in the form of a case study might have helped understand the concepts a bit easier.

The quizzes , projects were all good practice making us think and apply the knowledge we gained.

Thank you.

Lectures were greatly oriented and well presented. The content was brilliant and perfect for a beginner. It was eary to understand. The assignments were quiet challenging especially the peer graded one. Overall the course really helped learning and practising SQL and tested whether we have learnt something from it or not.

I took a different Data Analyst Professional Certificate on Coursera, but this class actually taught the fundamentals of SQL and how it works. It made sense! This is the first in a series of four courses...Now I am excited to go to the next course rather than wanting to pull my hair out after the last program I was in.

This course was my first experience with this type of learning and it went so far above and beyond my expectations. Sadie is an excellent teacher and I found the course very easy to follow and interesting. I feel that I learned a lot in a short time and would highly recommend this course to anyone looking to learn SQL.

Great course. Final project needs some work and this course will be top notch!! For the project, it would be great if we could port the data into R or Python and do some sort of basic analysis of it. Would make it more interesting. I like the separate coding and concepts quizzes. The teacher is amazing and upbeat!

V​ery useful for beginners who don't know anything about SQL. You will learn basic things that are necessary, although sometimes these videos won't be enough and you have to do little research by yourself (watching videos on YouTube and reading some tutorials). Overall it's very interesting and with a lot of practice.

Good introduction to learning SQL, data science best practices, and tools to continue developing this skillset. The lessons and quizzes are well-organized and easy to follow, as well as give good food-for-thought questions to get the problem solving gears going. Would recommend to anyone getting into learning SQL.

The lectures videos are the right size. Assignments are too simple at times. Final peer-review assignment was decent difficulty and allows for a lot of involvement; it also introduces you to data analysis in a structured manner. Liked the course very much. I'd recommend it to beginners in SQL and/or data science.

I liked the way the material necessary for data analysis was presented and organized. I think there could be a bit more difficult exercises during the course to prepare learners better for final project and give them better idea what is expected in real world.

Overall, it was awesome and well designed. Thank You.

Absolutely wonderful course. For someone who knew absolutely nothing about using SQL, this course has helped me to understand SQL coding and more importantly understand the logic behind trying to attain the desired result. Would absolutely recommend this course for anyone interested in a career in data science.

P​ros: great course with good content and examples.

C​ons: the final project description is very confusing. I spent >2 hours trying to figure out what to do. This link helped greatly:

Good! The information is helpful! But I think you could have done better to convey the material by giving examples and the way you want to solve the problems (all should be shown on screen) instead of just saying. I was quite a little bit difficult to understand and follow the table description you talked.

This course if very well organized. Our instructor explain very complex theories in a simple manner in which a person with a very less knowledge can apply. The quizzes are also designed such that the learner gets a full understanding on what's going on. I am very happy that I chose to do this course.

This course provides me the basic techniques to jump into the electronic medical records and start to code queries and provides reports to Clinical and Research Management. The test are intense and the final project is a real challenge. The good news is I learned to code as a beginner SQL programmer.

Well structured and covers the basics of SQL queries. One thing that could be added is a guide explaining some of the different software the is available for running queries locally, rather than through the web page portal that the course offers. Otherwise the course was an excellent introduction.

I ever thought the programming languages were difficult to understand even a basic one like SQL. But after I enrolled this cause it changes my mind a lot. It's not really hard whether you pay intention and apply good tips from the instructor. Hopefully, It's my first step for continuing this kind.
