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.

Simple and straightforward introduction to SQL for business-oriented/frontend-facing end users (data analysts, data scientists). Very good as a refresher for those, like myself, who have been exposed to SQL in the past but did not have much opportunity to use it. Instructor covers the course material without overloading with technical jargon, and mentions best practices, which some courses lack (material addresses the 'how', not necessarily the 'why').

So far this course is great for introductory classes. I took IBM's SQL for Data Science and I had a bad experience. Here the course is very well structured with clear concepts at a well-taught speed. I highly recommend it. So far 5 stars. I'll update this review once I'm fully done

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.

Great course based on instructional videos and design. However, mentors in the forums seemed not to always be helpful or sometimes even misleading.

The course was great. It helped me learn the basics and little things but of great importance, to be kept in mind while writing out the SQL queries for data analysis. Thanks.
