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!...

Nice that it doesn't expect us to know SQL and programming well. But not nearly enough exercises to understand how to do the queries well. I am feeling lost on the practice tests especially.

A well-structured course for those who are eager to gain knowledge about SQL.

The activity, test, and the mentor are very good and the best part is they showcase a bit of industry knowledge.

Great course overall! Only gripe is the poorly executed end-of-the-course peer-reviewed case study. The course does not prepare the student to know how to use the in-browser SQL terminal.

Really good information about SQL for the beginner but actually that informations are %80 in SQL so if you wanna or start the Structured Query Languages here is a good place. Good Work :)

Good basic course. I would have preferred more coding practice and fewer lectures. Also would have liked to have seen the breakdown of my final exam grade. It's a good starting place.

Best for new learners who started their journey in the SQL world. But the video lectures are simpler than the assignments and quiz, the lecture should also include more question solving

Great course for begginers!

-Simple explanations and good examples;

-No need to install anything;

-I would say that some questions are unclear.

Overall, great introduction to SQL. Thank you!

Great course, with well explained notion, well documented. The only thing I could add is that some exercises could be updated. Creates confusion when trying to solve.

Great presentation.

Honestly it's not obvious why it is called sql for DATA SCIENCE.

In my opinion it's just SQL Basics.

It's pity that there weren't window functions.

But generally the course is good enough.

great beginner class and also teaches critical logic thinking, which is what most business want out of Analysis type of jobs or Data Science in general, something useful and actionable.

There were a handful of errors in the video lecture's text on screen and lecturing. Some parts were hard to follow because of that. Otherwise the assignments and material was helpful!

Great course work! Loved the pace of the course and the examples. The instructors speech was pleasing and easy to understand. Would have loved more difficult SQL queries for practice.

Decent course. They could give some useful info on using SQL, downloading it etc on you computer and using it in combination with some common programming languages like Python and R.

great assesments which tested if you listening and paying attention. However from half of course there are not many extra new things to learn, they keep recycling the initial topics

Great course, easy to understand explanation. The material is well organized, useful links to additional resources where you can get more knowledge. Need more practical assignments.

Enjoyed the course and found it useful, but why the f*** is UC Davis sending me fundraising emails about something totally unrelated that has zero relevance to this? Totally not ok.

Thank you to everyone who is in charge of this course. But the training platform is not good and does not support all orders sql and there must be training after each lesson. Thanks

A great course to get started with SQL.The course is well structured and the pace is just fine!Coding questions at the end of the module really help in testing the concepts learnt.

Part 2 of Peer Assignment is a bit difficult as the whole course has not go through related example before.

However, the basics techniques of SQL can be learned from this course.

Very good explanations during the course, but we were working with data that weren't making sense, like texts data types.

A lot of records without real foreign key in their tables.

The content was great. Several SQL typos on the slides irritated me. And I already had signifcant background knowledge, the course was quite demanding for an introductory course.

It would be better if u gave us some practices to do so when the coding tests came we would be more prepared and know how and where to place the codes in which oorder and manner

its a good course to learn basic SQL but it teaches SQLite which pretty much the same as SQL with few changes. The course is good with many assignments but the test was tough.

THE COURSE IS SO MUCH COMPACT AND EASY TO UNDERSTAND FOR THE BEGINNERS. THE VIDEOS ARE VERY MUCH COMPACT AND SHORT SO ONE CAN EASY UNDERSTAND WITHOUT LOOSING HIS\HER PATIENCE.
