О курсе

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 was pretty good for a beginner. The instructor was very clear and explained all the concepts in a very easy to grasp manner. However, the entire course could do with more coding exercises. Concepts such as joins, group, etc could be better understood if there were more exercises. Also, during the coding exercise (at the end of the week) it would be really helpful if correct answer and an explanation would have been provided. Having said that, its really good for beginners and I would and have recommended this to others.

=) Very clear walkthrough of important concepts in SQL and why use certain functions for certain tasks.

=( Wish there were more practice questions so it's more interative.

=( Also it would be great if there are more "real-life" SQL practices that involve solving for an actual question that you might encounter as a data scientist working for a tech company.

Thanks so much for sharing this with us, Sadie!

Thought some of the intuitive thinking was a bit challenging, but really liked how the sqlite server was built into the course and didn't require any download or off-site work. Think some of the time estimates should be a bit longer, but overall good course.

Good course for anyone starting to learn SQL but the course needs more assignments to ensure that the learners have got a good understanding of the concepts. Also, the final project is a bit overwhelming to do without prior experience in SQL.

A nice course for introduction with SQL but they could have used the software currently used in the industry like oracle's MySQL or SQL server.

Would have been better if there was a chapter on connecting to an sql server from an application or gui.

Although the information and topics in itself are interesting and the course gives a good overview, the individual videos have a lot of repetition (in 5 minutes an intro, the main part and a summary), and I find the person who gives the course hard to listen to, as it often seems like she doesn't understand what she is saying. Also the questioning in the case study is very unclear - watching the discussion forum I'm not the only one who struggled to understand what they want. The provided answers for reviewing your peers are so widely interpretable that I myself got max points from 2 students for 1 question, while the third gave 0 points. And that for several of the questions. Overall not satisfied over the quality of this course
