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.

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.

The Peer Graded Assignment was challenging and the really helped in refreshing the concepts with applications. The coding assignments during different modules were helpful in getting the coding mode on.

Perfect course! But recommend the last main exercise do more readable and understandable. It is difficult to read in a text file, single-color task and it is not always clear what needs to be done.

This class has already paid for itself. I have used what I learned to write SQL reports to pull reports from our test database. I look forward to taking more classes in SQL Data Science.

It is a very hands on course in which you will learn a lot about SQL but also be able to practice a lot. The instructor is excellent and the materials are great. Definitely recommended.

I was a great topic, but just as feedback it should include more practical work since lesson 1 because, at least for me, it was difficult to put in practice the theory doing a test.

Great course for beginners to get their hands on SQL. I would advice the instructors to add more lessons on advance SQL topics like triggers,procedures,foreign keys,with clause etc.

The course was excellent because I could learn about general topics about SQL. For that reason, I want to study more about Data becasue it's really necessary in the current world.

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.

Though this course is on the foundation of SQL, I am completely taken away by the the teacher teaches SQL. I will strongly recommend anyone who wants to learn SQL. Thank you.

SQLite did not offer many features required to answer the questions. Would recommend a higher version of sql to help do more analysis and answer quiz questions still better.
