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.


Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

Course would be much better if you can work alongside the instructor. Using presentation slides in a coding class is not ideal imo.

創建者 Мамедбаков И Р


The lecturer maybe is a good data scientist but does not have the skills of presenting or explaining material in an easy manner.

創建者 Chan J J


should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.

創建者 Chen K


Course schedule was good , but content is a little short. To make improvement, should present some example during the video

創建者 Thais S B


This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.

創建者 Mohsin K


This is a good course on SQL for Data Science. As you will particularly start from scratch and go uptil tedious methods

創建者 Dhwanil V


The overall format was quite good but it would be more helpful if more examples are included in the lecture videos.



This course is helpful for beginners, but I felt that some explanation weren't clear and quizzes were challenging

創建者 Saswata B


More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.

創建者 Smit P


Instructor should have explain each code by performing practically on pc instead of showing only image.

創建者 Nick J


not really relevant to 'data science' its more of a general basic introduction to CRUD and joins

創建者 Ayush K J


examples for important concepts were lacking like the use of GROUP BY and CASE statements

創建者 Christopher M


Course teaching was excellent, but the final assignment questions were terrible.

創建者 oli c


Clear instruction, but quite easy. Would prefer if it was more challenging.

創建者 Islam M S M


The Assignment was mis worded and didn't reflect the content of the course

創建者 Tessa S


Nice course to get an introduction to SQL. Not so much practice material.

創建者 Abdullah F


Just teaches SQL. Nothing is taught about how its used for data science

創建者 Simone D


The course material seemed prepared in a rush, with several mistakes.

創建者 Greg L


Quizzes poorly and ambiguously worded, database carelessly extracted

創建者 David A


It could be harder with some excersice that make the student search

創建者 Daniel E


Good content but the questions are badly worded and need updating.

創建者 Melissa V


Need to take a more in-depth class to fully understand this class.

創建者 Matt E


You can learn this stuff on your own. You don't need a course.

創建者 Priyanshu V


Some topic is not cover like constraints alter modify default

創建者 Tim S


Quite easy. The peer-reviewed assignment is also very easy.
