SQL for Data Science

University of California, Davis via Coursera


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!

Start your review of SQL for Data Science

  • This 4-week course introduces basic methods in manipulating SQL databases including: filtering, sorting, calculating data with SQL, subqueries and joins in SQL, working with text strings, date and time strings, and case statements with SQL. This course is helpful for SQL beginners to have basic skills in SQL. But if you want to perform well in data analysis with SQL, more practical exercises are needed.
  • Excellent course teaching you the core concepts of SQL, the basics you need when you want to enter the data science world. SQL is required in almost every job as a data scientist.
    After finishing this course you can comfortably start your data analysis with SQL. It will not provide you with all the nitty-gritty details of every SQL variant, therefore you will further need to study and read the docs.

    This course is a good starting point to become an SQL expert, an enabler to getting started. From here onwards I would advise you to practice a lot and apply the best practices explained in the course.

    DietCoke completed this course, spending 2 hours a week on it and found the course difficulty to be easy.

    I do not recommend this course. This course introducesvery basic stuff but requires you to do more advanced quizs and assignments. For example, the instructor doesn't talk about how to iterate each columns in a table, but in a quiz we need to do so…

    This is such an excellent beginner SQL course.

    If you are seeking hard challenge however, prepare to be disappointed. The course just teach queries in SQLite but does not go in depth regarding data types nor table creation. This is because this course only teaches the fundamental skills of data scientist - to query and analyze data, not create database.

    The quiz and assignments are actually very easy, but if you make it complicated then you will go down the rabbit hole. The course is supposed to be fun and motivates you to learn SQL.

    I highly recommend if you know nothing about SQL or Data Science! It's a really good intro course!
