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!...

This course is designed with beginners in mind, and it is an excellent introduction to SQL. I intend to further my knowledge of SQL after taking this course. The instructor did a terrific job.

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.

I accessed this course just to evaluate this as a potential course for my colleagues who have working knowledge of SQL (running stored procedures but not writing own queries). This course is good for anyone who does not even know what SQL is. I like the instructor too, her pace is adequate and ability to transfer knowledge is high. Definitely recommend this course to anyone who works on "data"

This course is excellent! I loved that I could test queries and be creative. I really got to learn what I could (and couldn’t) do with sql. I definitely feel more confident with putting SQL as a skill on my resume now.

Clearly-explained, organised lecture flow and materials, easy to follow, not burdened with great details for beginners while emphases are made on crucial aspects of database management with SQL. The course fuels motivations for learning outside of the class. For a no confusion foundation on SQL, this is a great course as it really builds in me the confidence to claim a new skill and to take on my own project!!

Excellent intro to SQL. I've already recommended it to my Operations manager as a pre-requisite for read access to our SQL databases.
