It was just the refresher course I needed after not having done much SQL in the past year. He covers an amazing amount of ground in just 9 hours. The instructor is excellent (clear explanations, easy to understand, extremely knowledgeable), and his style of constantly requiring the student to apply what they've just learned with practice queries proves to be a very effective method of learning. ★★★★★ You really can't beat this course for the value. ★★★★★ Here’s reviews from real students that took this course ★★★★★ With over 17,000 students and a 4.6 rating, you won't find a better source to learn SQL for Data Science elsewhere.ĭon’t just take it from me, take it from other students that have taken this course. Just like my other courses, I follow the no-student-left behind principle which means that I start from the very basics. You do not need any prerequisites to take this course. We move step by step into more advanced topics as we delve into the world of advanced querying techniques using subqueries, aggregations, joins, rollups and cubes, window functions, transposing & ranking data and using conditional expressions in very interesting ways. After completing the course and all of it's assignments, I promise you, you'll never be afraid to look at a large SQL query again. There are over 100 puzzles scattered throughout the course with in-depth solutions providing plenty of opportunity for you to practice. You'll learn the skills you need to extract critical insight from data sitting in a database. 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.Īlthough we do not have any specific prerequisites or software requirements to take this course, a simple text editor is recommended for the final project.This course will turn you into a SQL query wizard. You will discuss topics on data, and practice using real-world programming assignments. You will use case statements and concepts like data governance and profiling. You will learn common operators and how to combine the data. You will create new tables and be able to move data into them. You'll start to work with different types of data like strings and numbers and discuss methods to filter and pare down your results. It will build on that foundation and gradually have you write both simple and complex queries to help you select data from tables. This course starts with the basics and assumes you do not have any knowledge or skills in SQL. You will begin to ask the right questions and come up with good answers to deliver valuable insights for your organization. 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. 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. 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. This is a data scientist, “part mathematician, part computer scientist, and part trend spotter” (SAS Institute, Inc.). 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.
