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,...

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!

Excellent Course for beginners. This course doesn't exactly provide tons of information on coding and syntaxes but a great start for people like me. I have enjoyed working on SQL through out the course.
By Mihkel L•
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.

Excellent course material and instructor, I applied these codes in biological databases, which provides me a lot of understanding of those function, earned me a good value among my professors and peers

A good option to start in this topics, is easy to understand the topics and is necesary to study more things diferent to the videos and the lectures, also is very important practice all the topics.
By Marco P•
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.
By Elena L•
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.
By Sylva M•
Really useful course for me. It takes you from the SQL beginners to the level, where you can write your own queries and easy read the ER diagrams. I appreciate a lot of practice during the course.
By Pranali M•
This is amazing course . Once you join this it gives complete information about SQL basics.To improve knowledge of creating databases it is very important course.I am glad to become part of these.
By Yee L•
Exactly what I signed up for. Basic understanding and syntax learning. For anyone looking to further their sql writing, I believe this course and the rest of the curriculum will do perfectly fine
By Kevin D•
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
By Carolina C•
Great course! I had zero experience in SQL and I´ve learnt a lot of useful things. The final project of the course was very interesting. Looking forward to the other courses in the specialization
By Astha b•
The instructor was awesome, whatever she taught was enough to do the assignment. I fell in love with her way of teaching, and now I will also do UC Davis specialization. Assignments were good.
By Fernando B P•
By taking the course you can learn how to use the principal commands for database queries using SQL and the practice exams help your to develop the ability to perform the theoretical knowledge
By Shi Q•
This course is very well paced and easy to follow. It won't go extremely deep into details, but there's definitely sufficient information for you to lay a good foundation for future studies.
This is a very helpful and well-designed data course. I love the way the teacher teach me knowledge about SQL. I highly recommend this course for anyone who is interested in data science.
I am very exciting to use SQL help me analyze data, and it is a powerful and easy-going language for me to use in future modelling & analysis work. The course is really helpful, thankyou.
By Samuel E•
Great program that even if you know nothing about SQL in advance - the course will equip you with the most important knowledge to allow you to dive into the field of SQL and data science
By GUDIPUDI R•
All the concepts are explained in a very structured way and the course made complex queries too very easy to understand. Definitely try this course for sql. No regrets and very happy:):)
By Johanna P R•
This class has already paid for itself. I have used what I learned to write SQL reports to pull reports from our test database. I look forward to taking more classes in SQL Data Science.
By Yuyan L•
Great introductory course on SQL, you can learn a lot from the definition of relational database system to specific queries used to pick out target information from huge amount of data.
