课程概述

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!...

I loved the practices. I learned alot But I think some of them had mistakes... The online visual studio code never worked for me! It might be good to make a video that explains how to work with it.

Good course for beginners.- classes are fine- quizzes evaluate quite well your understanding I think- the final assessment contains plenty of VERY ambiguous questions and I think it should be reworked

I took this course due to a new project at work which involves checking the input data by querying it using SQL scripts. This course has really eased my job. It covers the basic stuff pretty thoroughly. I recommend this course to anyone who's just starting out (or aspiring) to be a Data Scientist.

The course is great at introducing the basics of SQL. It is engaging, encouraging, and fun. I highly recommend it!!! There are some confusion points in the slides and assignments, but overall, there are minor. Very worth it -- I learned so much and feel more confident in using SQL in the future.

Wonderful Course. Covers almost all the Aspect in one way or the other. Found the final assignment difficult to do as it is a sudden difficulty increase. But it does help improve the skill, also let's us see the real-world analysis,problem solving required.

Thank you, Sadie Ma'am and Coursera.

Really great SQL course for a total beginner. As someone that has attention deficit disorder, the formatting of the course is very ideal. First module give you a lot of history and context of SQL which I think is important for coding - very necessary to understand it's role in the real world!

Loved how there were code blocks on the browser. The quizzes were the perfect level of difficulty, decently challenging and I feel as if they really reinforced what was taught in the videos. The final assignment was also a great way of assessing what was learned throughout the course.

This course is amazing. I have never get into SQL before and after the course I feel that I know way better now. It's a great start for people that never learned SQL before. Now, my next step is to do more SQL courses to be better prepared to become a data scientist in the near future.

I took another Data Science course from Michigan and it was horrible! I was concerned about going into this course, but it completely regained my faith in MOOCs and Coursera in general. This is a great course without question. Take your time on each assignment and you will learn a lot!

I really enjoyed the content and pave of this course. I am brand new to SQL, and this course has given me the confidence to look at a query and not be freaked out :) I am confdent that I can now write and execute basic queries and understand the results after completing this course.

The instructor has explained the topics with so ease and lots of examples. The thing I loved about this course is the practice questions provided. They are well-tailored and helped me to understand the concepts well. A must course if you are looking to start learning SQL from scratch.

It was a good start to the basics of SQL. I would request for inclusion of more sessions/videos in this course. These videos can enable students to gain deeper knowledge of SQL. Also, I request one to one sessions with the mentor. This will help in clarification of queries/doubts.

This covers the right fundamentals especially for those who are new in SQL. This has the right recipe of how to profile the data right from the beginning. I encourage those who are wanting to upskill their analytics skills or any one with no experience with SQL to grab this course.

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

SQL for Data Science is an excellent course for beginners or data professionals looking for an extensive refresher. The instructor Sadie St. Lawrence did an outstanding job teaching the material, keeping a steady pace, and motivating the students to learn and finish the materials.

I enjoyed the course and learned a basic understanding of SQL. The final project is very difficult and seems geared more towards advanced SQL users. If this is your first exposure to SQL you will find the final project frustrating and you will need to refer to other texts to t

I felt this was a great inteoductory course for me. The content was well organized and presented. I would've liked to see the different tables coming together rather than just the SQL query (especially when learning about the different joins). Overall really good. Thank you!

Course was great. Video's short, easy to follow. Quizzes were challenging but doable. Final project very challenging. Only suggestion, would be nice to work in an actual database. Was frustrating working in the tiny box provided to run sql queries & output was very limited.

I thought that this course would be really basic but covered topics from beginner to intermediate, and I feel that I learned a lot during this course. It is not the typical course in which you learn really basic stuff and cannot use it in your work. I really reccommend it!

The course is well organised and the quiz along with the coding questions tests one's knowledge very nicely. This course provides a indepth revision to the people already knowing SQL . To me this course provided a good revision and also helped me to learn some new concepts.

This course was really intensive and the course material is high-quality. The discussion and lectures were really helpful and straightforward. By far, the best course I had for learning SQL. I recommend this to everyone wanting to get familiar or diving into SQL as a start.

Loved this course. Easy to follow videos, they go straight to the point and you can practice queries right away from the first lesson. Gradually increases in difficulty and you end up doing a very interesting and helpfull assingment. I fell I earned all the basics in SQL.

I liked the course and the way it was taught. Just a suggestion if possible for coding from the starting of the module till the end that is for the complete lectures practice questions can be given so that entire coding can be practiced. Thankyou for the great opportunity.

It is a good course to introduce you to SQL, it is for data science so I feel I also have to know more about how to create tables and organize them in order to make a better job. All in all, I have learn variety of queries and I have made pretty useful classnotes. Thanks.

The MCQ in between lectures is extremely helpful in keeping up to the content. I also especially enjoy the coding questions that are really practical in helping learners understand and execute the knowledge covered in the lecture. Overall great presentation and structure!
