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.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

The teacher has really good knowledge of SQL and I really respect her for that, but as someone who is not familiar with SQL finds it difficult to give quiz without any side by side practice of the topic
von Ahmad S•
Nice course! Only giving it low stars because the assignments are so out of data. Please update your assignments corresponding to updates to Database.

It's very basic SQL, definitely not challenging for anyone with SQL experience
von Rashid S S•
The course was not easy to understand. Because the lessons were not sufficient enough to understand the questions in quiz and final exams. I think if all the things are described in a more elaborate fashion with a lot of examples it would be easy for the learners. Actually in this course I've to relay more on google and internet rather than my course lessons which was very disappointing. I personally think this course is not for a beginner student who really wants to learn about sql.

The Course examples were very little. Demonstration of new commands while teaching them would've been very helpful. But, there were little to no examples related to the teaching materials. There were gaps in concepts that required further reading to understand. Some syntaxes were used before being taught.

I can't pay for the course to get certificate. The free 7 days subscriptions never ends. So I can't send the tests to get results and get the certificate.. Lost a lot of time... Too bad

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!
von Harshvardhan K•
This is just one of those courses, everything about it screams professional. The slides are concise, and mostly provide all the content of the lecture itself, the instructor is great too. However the real gems of this course are the Exercises/Coding Assignments. Every question is varied, and at the end of the course, you will yourself learn a few neat tricks on Joining Tables, Grouping multiple data, and Complex Subqueries.
I would suggest to include a few more examples, for things like Self-Joins, Grouping, and Operations. Keep in mind, this is more of a beginner course, but it covers enough topics to dive into Analyses of your own!
von Maria C F•
This is such an excellent beginner SQL course.If you are seeking hard challenge however, prepare to be disappointed. The course just teach queries in SQLite but does not go in depth regarding data types nor table creation. This is because this course only teaches the fundamental skills of data scientist - to query and analyze data, not create database.The quiz and assignments are actually very easy, but if you make it complicated then you will go down the rabbit hole. The course is supposed to be fun and motivates you to learn SQL.I highly recommend if you know nothing about SQL or Data Science! It's a really good intro course!
von Jacquewyn C•
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.
von Arnaud D•
This mooc is really good, Sadie did a good job
positive point :
well constructed quiz
The practical cases allow you to apply the different tools
the slides in the videos are synthetic, with the objectives always stated at the beginning and a summary at the end of the video
negative point :
the questions in the final assignment (Data Scientist Role play) are not always clear
the codes are not detailed enough sometimes
I would have liked to have more details on the Many to Many relationship as a conclusion I recommend this mooc, offers good skills in SQL

Anyone with a passion in SQL can learn and comprehend this course. To excel in this course, the more you help to look at your peer's problems and resolve theirs, the more you learn on how to overcome yours faster. I think many students are a little lost when the ER diagram is not displayed in the intro for each of the video using it to teach. Overall, Professor Lawrence is awesome in her clear and easy to follow teaching. You will be challenged to think and resolve real-world project, be diligent in your own work and you'll feel your mind is growing!
von Anuj S C•
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.
von Charae B•
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.
von Nina L A•
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
von Zenia B•
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!
von Reuben Y J J•
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').
von Elizaveta P•
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.
von Ravilall s•
hi, this course was very new to me but found it challenging but yet interesting. This course has exposed me to fascinating aspect of data science and how data is kept (databases) and how data can be retrieved by using skills learnt in this course. Based on the knowledge received i will endeavour to expand my knowledge in this area even through You Tube Videos. Thanks to the Coursera Team and the Commonwealth Team, Canada.
von Lara B•
Before this course I had no knowledge in SQL, neither any other programming language really. This course quickly got me acquainted with what SQL is, what it can be used for and how to use it. The videos, presentation slides and transcript were very useful. And the combination of theory and practice examples helped with a effective and efficient learning process. I recommend this course to anyone getting started with SQL.
von ARNOGIANNAKIS A•
Great introductory course. My only complaint is that the lecture has a level of difficulty 1 out of 5 and the practise quizzes are 4-5, so upon reaching the quizzes of the week, personally I would get discouraged but after some grinding, I would solve them and feel confident about my understanding on SQL. But, I wish there would be some bridging between the lectures and quizzes and some tutorial for sqlite environment.
von Joshua P•
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!
