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.

A good course especially for the beginners. Part 2 of the assignment, however, is more intense than the expectations, incorporating some areas not included in the course, which I guess is to compel learners for more research.

Up to this point, this is the best SQL course that I've ever taken. Not only does it give students a ton of practice with SQL code, but it also tests students on SQL and database concepts and on what to do in common SQL-related situations. In other words, this course covers both the "how" and the "why" with an ideal proportion for each instead of placing too much focus on just one of those.

It has good explanations and exercises.

I only wish it had some kind of tutorial of how to install a SQL software, and to have exercises to input or modify data in a database.

Even though this course is aimed at beginners, the assignments encourages a person to do some additional research. This simulates how a person should continually research and explore to enhance one's knowledge and experience. The final peer graded assignment was fun. Make sure you allow enough time to spend on it and you will reap the rewards.
