À propos de ce cours

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!...

It was a great course and I've definitely improved my SQL skills, however there were a few things that could be improved. Practice questions and quizzes should be placed throughout the course material, not at the end just before the final quiz. Secondly, the content itself could be explained in better ways. Not always very clear.

No practice examples at all. Videos have only theorethical queries without results, so you can`t see how it works on practice. Reference to SteckOverFlow is awesome. Why should I pay money for nothing?

This is a comprehensive SQL course. It might take a bit more time to complete the assignments than stated by its creators.

I personally found the course really helpful. I recently started working on SAS and this SQL course came in handy. I'm planning on taking a course on SAS now. I'd recommend this course to anyone who wants to get started with SQL, it's a pretty basic course.

This course is a great course for people new to SQL. No prior programming experience is necessary, and Sadie is very to-the-point while still being very welcoming and friendly. I highly recommend this course.
