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 has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

Good course to learn a overall high-level view of SQL. However, to get the full grasp of SQL you need to practice SQL from external resources as well. This course explains SQL commands in a brief and concise way.

Great course! I really learned a lot from the videos and instruction. I kept going back and forth a few times. But, I felt comfortable in doing so. Take this if you are just starting in the data science field

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.

Great Course. Very well structured and comprehensive. The participants get a good grasp of what a database management system is, how it the data are stored in it and how SQL is used to extract data out of it

This course is well designed and Sadie did a good job of pacing/explaining. It touches various SQL concepts. The best way to learn SQL is to use this course but keep google handy for any additional research.

Decent starting point for any individual interested in coding with SQL. I would suggest the creators of this course to clarify the final quiz a bit clearer as some of the questions are a bit too generalised.

A very nice course to start learning about SQL. I would suggest more datasets to do more practice, but overall, I felt excited and confident to go out and practice by myself. That's what I was looking for!

Very helpful. I remembered something from previous times but it helped me to get back on track... although in my assignments I must re-learn the syntax - cause it is somewhat different, it has appeared.

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.

Course is very well structured, the explanations by video and the relative exercises upon the different themes explained, are excellent, so I've learned in a fast, efficient and profitable manner.

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 was more challenging than I expected, the assignments will definitely make you think. A good intro to SQL. If you have no background reading the supplementary articles will be very helpful
