About the Course

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!...

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.

Helpful but very dense towards the end, where it mostly gives brief examples on how to use the more advanced SQL features. The final assignment would be relatively challenging without prior experience or further reading. Some of the questions are phrased somewhat ambiguously.

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

I have learnt a lot, this is a very well organized course and lessons are very intersting. I would improve the wording of the excercises, in particular the text of the final assignment, some exercises were difficult to understand. In general, I have enjoyed this course

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 !

No specific tools are being used, they talk about SQLite but you don't really use anything. When programming in the coding quizzes, it does not automate as it will do in reality and it gets too dull to go and check the names correctly when it wouldn't be needed to.

The instructional videos were excellent. Overall the course help me remember what I'd learned about SQL many years ago and also introduced me to some new knowledge.

The instructions on how to evaluate some of the questions in the final assessment were ambiguous.
