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.

While I did learn some useful bits, I found the course lacking. I think it could have been much improved if certain conditions would have been met:A. More practice! You don't learn a computer language by hearing about it, you learn by using it. The only practice this course had were the quizzes, and they were far from sufficient. I would expect each lesson to be followed by at least some practice. I often found myself venturing to different websites in order to practice what I had learned, and learned more from that than I did from the actual course.B. Better explanations. I found the explanations short and sometimes lacking. Moreover, at times there was no synchronization between what the instructor was saying and what was presented on screen (e.g. she was talking about products when the example presented data of employess). It's a small thing but can be very confusing. It is very important to be precise here. Again, I found myself reading elsewhere in order to better understand certain concepts, which I might as well have learned elsewhere altogether.C. Examples! Again, you don't learn a computer language by hearing about it. You learn by using it or by seeing how it is used. Whenever I'm taught something, I want to be shown examples of possible ways to use it. Examples were scarce and incomprehensive.D. Applicability. The course is called "SQL for Data Science", yet I found very little in the way of applying SQL to data science. I would expect a lot more tips and tricks and examples of real-life problems and how an actual data scientist would tackle them. There was almost none of that. There were positives as well. The instructor was pleasant, the course was pretty well structured and did provide an introduction (although not much more) to SQL. But I did not get what I was hoping for.

Some of the quizzes do not make sense and I have to select something that is wrong to pass. It is really hard to follow sometimes and the content of the video mostly does not relate to the content of the tests. I had to google most stuff that came up in the videos, many quotes from w3 school (another provider of programming courses).
I choose to pay for courses on coursera so that I do not have to read through tons of free material online or get quoted content that is for free on other learning platforms. This course taught me some neat things but mostly wasted my time.

I finished the first course in the series, however it quickly became apparent in the second course that the instructors are unprepared and the assignments are thrown together without student learning as a priority.
If you want to learn SQL or Database systems, I highly suggest taking "Modern Big Data Analysis with SQL" from the CLOUDERA team and "Data Warehousing for Business Intelligence" from the U Colorado team.
Both of those course paths are much more informative, structured, and up to date. You are wasting your time if you choose this path.

I felt the course was put together in a hurry. There was a lot of information that was incomplete or just plain incorrect. The assignments were even more vague than I was expecting. OTOH It does lead you through learning very basic SQL.
Too much focus was given to SQLite which is not an industry standard. Perhaps using a free DBMS like Postgres or MySQL would have been better. Are there any interactive T-SQL or Oracle engines that could be put in a box like the SQLite here?

Nice course! Only giving it low stars because the assignments are so out of data. Please update your assignments corresponding to updates to Database.

This course is incredibly poorly designed and does not provide sufficient guidance to learn SQL.

I'm fairly proficient in R and wanted to add a database language to my data science repertoire. Most data science jobs ask for SQL so I thought this was the perfect starting point for learning. I found learning the language fairly straightforward, especially because many SQL-type commands are built into R packages (like dplyr). My job has a comprehensive relational database but, I usually use a point and click interface to make queries- now that I'm more proficient I'll start using SQL though. Additionally, I was hoping to pick up SQL before starting my grad program in analytics so I can "hit the ground running" and be ready for classes focused on database management and data engineering. I was able to accomplish this without any question.
I really liked the course, which is not surprising given all of Coursera's data science content is excellent. The final assignment was very thorough and helped put together lots of focused questions you might encounter using SQL as a data scientist. It really helped solidify my learning. For about $60, this was a no brainer for getting started in the language.

DO Slowly, Build up. This is a wonderful course and you will not know when you have learnt so many things. The instructor is wonderful she explains things nicely. The people who have designed the course must be working professionals because Of their depth of understanding of the subject and knowledge.
The most interesting thing about the course is you will learn a few things in a module then try your hands on. you don't even need a laptop to code because they have integrated everything on the Coursera's platform. I have watched most of the videos on my smart phone and submitted a few assignments too.
and the last part of the journey through this course for me is realization. You solve the questions given in the peer graded assignment specially part 2 and for a person who Has been listening the terms like PREDICTION, SENTIMENT ANALYSIS kind of stuff , Learning a few lines of codes in SQL from this course has actually let me do them.
Wonderful course Amazing team
Thanks Sadie St Lawrence

It was really helpful. As a beginner I really appreciated that it started right at the beginning. The videos were all easy to understand and well structured. I would recommend paying for this course to get the whole package because it really helped me to do the quizzes as well to practice. I found it helpful that it always consisted of a theoretical and a practical part.
The only negative thing was the very last assignment. It took me way longer than it said it would and I had problems understanding a few things around it. Looking through the comment section it seemed like I wasn't the only one. I think it would've been helpful to have another video or text before this to prepare better for this last assignment.

I took this course with basic knowledge of SQL, that is, I had experience in programming in the MySQL language. This course helped me understand more about databases and learn more about the structured query language operators used. I created a table with data for competently building queries, and therefore the code that was given in the lectures had to be adapted to my table. But you can download the Chinook Database in the public domain, as many examples are written for this data. The training is conducted in the SQLite language, but also tells about the features of other languages.
Have a nice course to everyone who wants to study it!

It was a lot of learning - not as simplified as I initially anticipated. I learned so much, and the practice quizzes as well as graded ones provided a platform for efficient amount of practice. It leads you through a course while reshaping your mindset on technology and data, if you are a beginner, and very new at this.
As an ethnographic researcher from the tangible fields, shifting the qualitative thinking capacity trained from anthropology and ethnography enabled me to perceive, correctly, the difference of ethnography from the technology concepts, and adapt to a new mindset in behavioral data analysis.

Very engaging and active course. I liked how there were knowledge-based quizzes and quizzes that we had to utilize coding to complete as well. The peer-reviewed project at the end took considerably longer than I anticipated and was more difficult than I anticipated, however, I think this exercise was important for real-world learning to occur. Having this project peer-reviewed (and reviewing others) was instrumental in learning as well. The diverse set of learning and grading in this course has been excellent.

This course was really great. I enjoyed it and the lectures were detailed and right to the point. The example code in the lectures was extremely helpful, but the assignments still left room for critical thinking and creativity when writing code. If you are looking to learn SQL for the first time, and you already have some programming background, this will be a quick course for you. If you haven't programmed before, you may find this a little more challenging, especially the Peer Review Assignment.

I took this course without having any background in programming; I had never written a single line of code. This course is fantastic for beginners like me who saw the power of SQL and the potential of SQL to solve current business needs. Completing this course has empowered me to take more computer science classes; I now KNOW that learning a programming language is not impossible, and when one understands the principles and power of SQL, an entire new window of caree

I really enjoyed this class! The instructor broke everything down in a way that made it easy understand and fun to learn. I also thought the exercises were also very helpful in making the material easy to learn the material we had just reviewed. I looked forward to completing my course every week! Thank you for making this class so enjoyable! If this instructor is teaching another course that's relevant to Data Science, I'll absolutely be taking that course!

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').

I'm so satisfied with this course! Good structure, a lot of practical tasks and examples. In parallel, I solve hackerrank tasks and this course gave me everything to pass it easy.
Really appreciate final peer-review assingment, it looks close to real-life analytics and was a little bit challenging for me. But I had so much pleasure done it)
So strange pronunciation of SQL)) But I thank you a lot for this course and sharing your knowledge.

Being a beginner it was worthwhile to learn things and this course I think was designed in a way that can be understand my even a laymen. If you can spend a little more time learning concepts and practicing only then will you be able to have a clear understanding which helps build a lot of confidence.
This is my experience and if it happened to me I'm sure you will also experience the same.
All the best! God Speed Guys!

This was my favorite Coursera course so far. The instruction was slow and light enough to understand. The instructor did not present the material as overcomplicated, even if it was complicated. I really liked the additional links, and the intermittent quizzes.The modules and quizzes were instrumental in my learning because they gave me hands on practice. I look forward to continuing my learning. Thank you so much!

This course is perfect for my level as a beginner. However, the real study time is more than 20hrs as it was supposed to be. To learn deeply and actually understand the content, there should be some effort to self-learn and practice the concept. It is useless if just watch the video and click multiple choices, you must go around on the Internet, read more materials, create your own example and practice the code.

Clearly-explained, organised lecture flow and materials, easy to follow, not burdened with great details for beginners while emphases are made on crucial aspects of database management with SQL. The course fuels motivations for learning outside of the class. For a no confusion foundation on SQL, this is a great course as it really builds in me the confidence to claim a new skill and to take on my own project!!

Really enjoyed. Didn;t need to install anything, the practice questions were good. The best part was the peer graded assignment, i would have loved another peer graded assignment. But It was brilliantly taught by Sadie, also loved the fact that she gave many times her experience in real world project, that she use this a lot working on real time, this gave us a feel to the use of SQL in real world projects.
