I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

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.

Expect peer review section this course was good. That peer review section confuses a person that how to do the task and what needs to submit. So in the place of this peer review include completed a problem data along with instruction and some hints and grade that as other assignments of this course.

The contents are very accessible and well done, as well the support tool for exercise is great!
However, you should consider to improve the final assignment questions. They are not clear and the database needs a code book with the metadata. It was tough to get the meaning of each field and tables.

As introduction to SQL , I have found it very useful and well structered in order to get a better a grasp on the topic. The only thing I will improve is the part concerning self joins which by the examples shown in the videos I didn't get all. Maybe add more examples.
To sum up, very good course.

Great place to start if you have absolutely no SQL experience. Videos are well paced and thorough. The final project could use some cleanup--as indicated by the forums full of people asking the same questions. I'd take another in the series if it started around the level of windowing functions.

The material was simplified. I would have liked to have learned more advanced techniques in SQL. Most of the material is refresher for me. I've been doing SQL for over 10 years now. I was a little rusty because it's not my day to day anymore. I would love to see a formal course on no-sql.

How can i say about this course. Overall, course isn't bad, neutral. Tutor's pronunciation and English is so good and accurate and she always try to explain the course in detail. Disadvantage of this course, it is so theoretical and doesn't have many practical explaining during the lesson.

Course gives very good info for beginners. I just wish there were more exercises between lessons. I felt overwhelmed by all the informations that I had to memorise before doing test at the end of each week. I think having more tests in between lessons would help me better memorise things.

The course is really great to learn basics quickly however it has huge drawback and that is grading peer asignments. Coursera should have courses without this. As i can not invest time in peer grading, now I can not get certficate though I have scored excellent in all the course quizes

The course is very good for a sql starter to get to know the coding world. I would recommend any starter in our company to take this course. However the final assignment is a bit confusing and peer grading created a lot of stress... that's the only reason for the 4 score instead of 5...

It was my first course in SQL and I liked it. In general, that's a good course with a lot of practice. Some things were tough and it would be better to cover them by more examples. Anyway, the course helped me to learn SQL and I'm going to explore the data world with my new knowledge.

AS someone who has never taken a data science course before, it was a good start. Some of the assignments required me to seek some external sources for extra material and learning but it was worth it. SQL is such an interesting language and I can't wait to use it for future careers.

Honest feedback, as an SQL beginner I feel there should be some short quiz to practice queries after every few videos rather than at the end of every week. Other than that the course was top-notch, it went into good detail and the peer-to-peer assignment helped a lot at the end.

I like the overall look, feel, and organization of the course. It was well paced and simple to understand. I struggled at times with coding questions as some are very ambiguous and there isn't always an easy way to find guidance in the forums. Overall, though, I was very pleased.

Overall a good course for the starters in SQL in Dtaa Science filed, however I felt it could be some more hands-on oriented with some more examples, and it was mainly of lecture contents, rather things could be shown visually for a better understanding. Thank You for the videos.

Would have loved to see more live videos of how to do stuff. There could have also been an SQL initial setup tutorials in the system which would have been more beneficial on how to setup a relational database. But, I was able to learn the basics of SQL and how it works overall.

Buen curso que permite aprender SQL de forma rápida y eficaz cuando buscas mejorar tu CV y obtener habilidades necesarias para el sector de análisis de datos. La última prueba es un poco compleja...¡dedicale tiempo! No te copies de los github que puedas encontrar en la web ;-)

Very good course for beginners to start and specially for people without any programming background. The assignment provided at the end of every module give a very good exercise for practice. Only thing is some real life examples could also have been included in the lectures.

Questions in the final assignment are rather ambiguous. More can be done to make the questions more specific and easier to interpret. Examples presented in the course were also very sparse and basic. However the syllabus covered the basics to get you started on learning SQL.

This is a very good and useful course to take if you work or want to work with SQL. It provides a very wide ranged knowledge on SQL. One recommendation from me is that it could be a slightly more hand-on in SQLite along with the videos so that sudents can play with the code.

I really appreciate the way SQL is taught in this course. The only limitation is that if the coding given by the student does not match the coding in the answer , then it is displayed as incorrect. However the coding might be technically right and generate the same output.

The amount of content that is covered in this course is very comprehensive. The videos are precise and very useful. The practice tests and weekly assignments are very helpful. The peer review assignment was very poorly worded and ambiguous. Other than that good job guys !

Please add a video in the course for instruction on installing any SQL Studio to computer. More practice exercises are needed in the course itself. Some of the videos in 3rd and 4th week were were hard to understand without proper examples. Overall a good course. Thanks!

For some people don't care about assignments, so they don't take the time to review the work of other properly. Two of three take time and they reviews my work and the last didn't care about and he gave me a bad score! It is not fare! I took the right time to do it well

This course is a perfect start for those who have no basis for SQL to learn basic statements and possible applications. However, the lecture videos are too short and do not provide enough examples. I have to spend much more time googling before doing any assignments.

I think the course is well designed for intorduction to sql language for data science. One more thing about the course is that I cannot open and use the sqlite. If there is a bit more information about the usage of sqlite, it will be great. Thanks for this course !
