課程概述

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!...

Great introductory to the SQL programming. This will definitely not only add another programming skill but also give me more capabilities programming in SAS. I would recommend this to anyone.

Absolutely wonderful course. For someone who knew absolutely nothing about using SQL, this course has helped me to understand SQL coding and more importantly understand the logic behind trying to attain the desired result. Would absolutely recommend this course for anyone interested in a career in data science.

Really great introductory course to SQL. I highly recommend taking this course for those who have little to no experience with SQL. All of the course work and material was easy to comprehend and very digestible. In addition, the quizzes and assignments were great supplemental exercises to reinforce the concepts that were taught in the course.

I really enjoyed this class! The instructor broke everything down in a way that made it easy understand and fun to learn. I also thought the exercises were also very helpful in making the material easy to learn the material we had just reviewed. I looked forward to completing my course every week! Thank you for making this class so enjoyable! If this instructor is teaching another course that's relevant to Data Science, I'll absolutely be taking that course!
