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!...

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.

Good overall course, I like the order of topics introduced and they're application to real world events. My only request for this course is that the topics go a little more in depth (explanation of more complex examples) and that there could be an optional video to watch where the instructor does the coding quizzes, and explains their reasoning behind the queries they create.

It's a good start for learning SQL. However, intensity of the lessons does not match the quiz and final assignments. Lectures are more simple and easy to understand but not enough to complete the coding assignments. You need extra resources or help to finish the course. After every quiz or coding assignment, i would expect to see the correct SQL queries to see our mistakes.

Good course to start learning SQL however I was expecting practice exercise after every lesson video but in this course we have to see 1st series of lecture videos and then practice in the end of the module which wasn't suitable to me as I couldn't remember all the concept what I have remember to practice and lastly the peer reviewed project was a big confusion to solve.

This course covers many great issues.

My only problem with this course is the way tackle SQL on the first 4 videos. I think I totally gut confused.

After, I read some articles which provided on reading material I fully understand the concept.

My suggestion is to change the sequence of some videos and put these videos after the student is done with reading part.

Thank you

This is by far the most introductory approach to SQL that I have been able to find, but there are still some details that expressed in a generic manner that don't allow for a solid base of knowledge to the complete beginner. to be fair, she does tell you to be prepared to have to look up a lot of things on your own (which is very realistic to real world use anyway).

The professor was really pleasant. The courses was really helpfull and I have a good comprehension of all the courses. Just one bemol, for the final exam, it wasn't clear at all for using the labsandbox, and finally I didn't use it at all but I spent maybe one day for finding how to answer to the exam and espacially how to run my codes for completed my final exam.

I think the course is interesting if you don't know anything about SQL, if you already works with it, you can learn something about formatting or maybe some functions but I think it is for very beginners with SQL language. In any case, if you don't know anything about SQL is a good course to learn the basics about it and start with an introduction of data science.

The course is pretty good. In particular, the quizzes and assignments are very useful to understand the concepts that are being taught in the course. I enjoyed it!

However, I will give only 4 stars because regarding the lecture videos I would have preferred that the instructor coded along with a sample database instead of showing the code snippets in a power point.

I thought this course was really useful for beginners in SQL, my only issue is that some of the concepts were not explained very well. I never really understood how to qualify tables, there were things you could do with text that were mentioned but never explained, etc. Maybe I missed something but some of the concepts they were very vague but then on the quizzes

The modules are carefully planned and precise. The reading materials are really helpful to get a better understanding of the subjects, and the quizzes at the end of each week are thorough and cover every important point. The one thing I can think of that can be improved is the way the teacher is presenting the lessons, it is unfortunately a little bit monotonous.

Thanks to this course I've found a job as data analyst, and now I write sql queries every day, which eventually make me sick of the select......from.....inner join*n......group by......lol Anyway it's a very efficient course that gives you all the necessary building blocks in a week (I finished it within several days). And the rest is gained gradually from work.

Overall great course! The lectures and lessons were extremely useful! However, for the final "project", it would help to have write access or some option to create a temporary table with either a WITH or CREATE TABLE VIEW clause. Also, maybe some documentation on what SQLlite methods you and can't use (e.g. you can't seem to use INSTR when cleaning text data)

This is a great opportunity for a beginner to learn the basics of SQL for data analysis. I'm confident that I can put SQL on my resume now! The end of the course is pretty worrisome though. It takes a few days after you've submitted your final for other people to finall review yours. You'll end up doing wayyy more reviews just to get others to review yours.

The instructor is great, explains everything nicely. The peer-reviewed assignment at the end was a real shock though. Hard to understand the instructions and quite a lot of work to do compared with the other assignments. I spent a lot of time on it. Then it is marked by one of your peers so you have to hope that you get someone who markes you fairly.

It is a good course for beginners who are not familiar with SQL. You don't need to install anything but can still practice through the quiz to enhance the basic commands.

The problem is there are some mistakes in the course material and these wrong explanations may be misleading for the students who are new and don't have sufficient knowledge of SQL.

I did enjoy it quite a bit. Unfortunately the peer review process can also be kind of a curse - none the least the clear possibility of fraud (I detected two assignments with the exact same final answer - not a couple of lines, either. Quite the long, detailed answer). But it was fun and the teacher was pretty good and expressed herself well.

I thought the course was, by and large, effective at communicating the lessons. The weekly quizzes and practice elements were also great. My only sticking point was in the final assignment. Having to update a .txt file (which is notoriously difficult to format) and review others' .txt files makes for a bumpy experience for the final assignment

Content is fine but I feel that the last peer review assignment could be improved by adding much elaborate data definitions and metadata to give better clarity about concept of fields. Just UML diagram doesn't suffice for in depth analysis. Also, please allow a better sql editor to use, just one query at a time is bothersome.

P.S: Good job!

I'm totally new to SQL and even as a beginner I found these lessons to be way too slow, assignments were interesting but the questions of the peer review were very difficult to understand. The teacher is very clear, the structure is logical and she's able to give good simple tips. I'll recommend this course for whoever wants to get into SQL

The course structure is quite upto the mark and the lecturer Miss Sadie explains all the concept in an interesting way. There are 2 scope of improvements I suggest for this course:

-Using MySQL instead of SQLite because SQLite isn't used much in the industry

-Including Windows Function in this course itself instead of the other course ahead.

I had issues with week 3. I think the outputs should have been included with the code during the videos so the examples would be more helpful. The forums were very disorganized. I commented on a post and asked a question but didn't receive help on either. Overall, I was happy with the class and am looking forward to the next one.

This course gives a really good introduction to SQL, no pre-knowledge needed and it feels like the level reached at completion of the course is very satisfying for a 4-weeks program.

The final assignment is a bit confusing and could be improved, but the lecture videos and practice quiz at the end of each module are very well done.

By Sandra C G

Liked the lessons a lot, the examns and the assignment is slightly more complicated to the queries shown on the videos though. The level of exercises shown in the video lessons should be higher so students know what to expect from the exams and assignment. Aside from that, explanations are clear and the course is very enjoyable.

I enjoyed the course and definitely know and understand SQL statements now. In the future, it would be helpful to provide additional tips on where to practice your SQL statements to help those of us who need that extra help.

The instructor was very clear in the videos which made it easy to follow. Thanks for a great course!

Aside from stumbling over words, and clear video cuts, I think the course was effective, however there could be improvements but showing more examples during video demonstrations and more detailed explanations. Some parts of the course tells you to do something without properly explaining or demonstrating the WHY behind it.
