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!...

Targeted to business people - explanations might feel unsatisfactory if you're more of a programmer. Final assignment took me a lot longer than expected as it required solving problems for which the course have not prepared me - the optimists will say that's a little of a real life learning experience.

It was good content but I wish after each concept or syntax, there was a sandbox example in-between videos cause it will help understand better and in terms of syntaxes not tested in the final review, we might have forgotten. Also, the peer-reviewed assignment was a bit much for my learning objective.

I feel the knowledge shared in the course was not extensive and also the lessons could have been more practical. Since I have already had hands on on the SQL DB's before, it was less of a challenge for me but overall content and the topics covered were good. Only if it could be more elaborate.

This course is OK. But the problem is mentor seldom answers your question in the forum, so once you encountered any problem, it's hard to continue. Also, the elaboration in the lessons can be improved with the aid of the output table, since only showing the code is inadequate for beginners.

Good: - coding assignments were good and lab sandbox/dataset lookup tool was useful Bad: - the learning material is a bit generic - given the course material, the final peer review assignment was too ambitious. I ended up resetting my deadline many times to finish the assignment.

Assignments and practice quizzes are great. Lecture videos should include ER diagrams because without them learners need to imagine the tables and application of each topic discussed. Also lecture videos should include more examples of each SQL function for better understanding.

This is a great refresher course for SQL, but the final project is disconnected from the material in the course. It is much harder than what is presented in the short videos and readings and feels like it was designed for a higher level class and then just placed in this one.

I found the final peer-review project to be a good challenge, but disproportionate to the challenges that preceded it. The material is fine for a foundational course but I felt the instructor really didn't add any value beyond what reading from a page or a slide would provide.

The course is interesting and really focuses on the basics, so it's good for people who know nothing about programming or SQL. I didn't like the final assignment, though. I felt it was too difficult compared to the content of the course and the Forum wasn't very useful to me.

This course teaches the very basics of SQL but in the final assignment gives real world problems, that was never mentioned in the course span. How to use the queries for analytics and gathering data and coming to some conclusion, these things are not available in this course

The lectures are alright. They do describe the basics albeit in a high level way. The programming questions, especially the final exam, are kind of confusing and poorly worded. There doesn't seem to be much in the way of connective tissue between the lectures and the tests.

By Iván G

I feel that this course strongly lacks of explaining the commands with real code sessions. Just being sat watching the Lecturer's explanations about the purpose of the commands without coding becomes a little boring and may turn out in doubts in the programming assingments.

Would be better to be able to see how examples play out. The whole course is just videos made up of 3-4 slides as backgrounds. No code is ever run so you can see the queries run. I had to seek out and download SQLite and a sample DB to run test queries to practice on.

The quizzes are lot more demanding than what we're taught. Good for someone who knows the basics of sql or other coding language (python or R) and wants to go over them. Too difficult for one who has no experience in any coding language and wants to learn here first.

I give it three stars because I did learn a few things.

I think my only recommendation is to add some more practise coding before the quiz available . For example, after we finish a video, have a practise code since coding is learnt by doing more often than anything.

This course is great at getting you started in SQL. The complexity of the assignments however exceed the practice questions available. Further there are not enough practice questions to become fluent in using the concepts described. Feedback: more practice questions.

What would really put this course over the top would be "side-by-side" practice of the material being taught. It's difficult to go through several videos in a row and then to take a quiz at the end, having forgotten what you learned in the first half+ of the videos.

By Sarah S

This was a good course, but as with other Coursera courses there is not enough practice of the material. The assignments are easy to do if you already know the subject being taught and very, very difficult if you are just relying on material taught in the course.

By Nazmus S S

I think this course does not provide opportunity to learn sql practically. It only gives the theory of sql language, which I think is not sufficient to get the whole idea. Another thing, the quiz and questions are way too harder compared to the lectures provided.

By Martina C

I think some parts are not explained well and lack of examples, furthermore complicated topic are treated fast and easy topic are treated in a deeper way. I found myself in difficulties and there isn't a way to ask a mentor more infos about the topic.

This course can give you knowledge of basics of sql queries (at least I got), but there not enough examples of how they work and practice, not enough ability to write queries on your own, sometimes not very clear explanation or mistakes in examples.

By Brooke H

This course was comprehensive however, it would have been more beneficial for the student to practice writing queries during and after each introduced topic. The first time students write a query is the very end of week one after watching videos.

This is a basic SQL course. I'm not sure why it is called "SQL for Data Science" other than that is a catchy title. I took this course to refresh my SQL skills. It did give me an idea of where I am weak, but I don't feel I achieved my objective.

El curso fue muy básico.

En mi opinión hubiera sido mejor si los contenidos de las semanas 3 y 4 fueran más prácticos.

Las preguntas del examen final tenían una redacción muy pobre y ambigua, y no había mentores encargados de solucionar dudas.

Good for everyone who doesn't know anything about SQL. It covers many basic syntax and functions with some examples. However, the contents still are too beginner level even it's introduction course. You need to study more to know all basics.
