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!...

Would have been better if there was a chapter on connecting to an sql server from an application or gui.

I wish there was a practical piece to practice after every video to help learn each new new skill.

As an already comfortable SQL pro looking to add a few badges to my belt, I went into this with an intermediate understanding. I found the course actually challenging, which on one hand was fantastic, but the monotone, stepping over every sentence, and flavorless videos ran by the same instructor, made this class very indigestible. Truly, I feel horrible for any non-English speakers who had to handle this course as first time learners. I'd be scratching my head, or running for the hills. I know the University of California has enough time, energy, and funds to put a good course together - so I'd lightly give this recommendation: find a speaker for your videos who can show emotion, deliver a speech, and knows how to teach a point. Maybe one that doesn't sound like they are reading from a teleprompter, and can deliver punctuation. It felt like one long sentence every video, no breaths taken. You made this course unnecessarily difficult with the speaker alone. Going right into the modules / quizzes that require specifically tailored, distinctly created queries done all by the user - you need to balance this course with at least an easy to understand instructor. This was not the case and I honestly wish I'd known that prior to signing up.

Although the information and topics in itself are interesting and the course gives a good overview, the individual videos have a lot of repetition (in 5 minutes an intro, the main part and a summary), and I find the person who gives the course hard to listen to, as it often seems like she doesn't understand what she is saying. Also the questioning in the case study is very unclear - watching the discussion forum I'm not the only one who struggled to understand what they want. The provided answers for reviewing your peers are so widely interpretable that I myself got max points from 2 students for 1 question, while the third gave 0 points. And that for several of the questions. Overall not satisfied over the quality of this course

I didn't learn anything other than basic theories and basic practice, which leads me to have another better course from another platform ofc.! I am more angry to Coursera, as it took money automatically, without even emailing me or any other information before taking that money. I had finished the course and they took money twice. they didnt inform that i have to cancel the course even after finishing! why would they? ! this is using people, nothing else. Just WASTED my time and money. that's all.

Lectures were stilted and repetitive, some of the exercises were poorly thought through and the peer-grading is a joke, with people grading me as having got questions correct, when having seen the answers I now know I got some questions wrong! Questions from peers went unanswered in the forums.

It stars strong, but on weeks 3-4 it lacks comprehensive examples and guidelines, and that makes you feel lost. Also, the final assignment is very hard, and it asks things in a non-comprehensive manner, which makes you spend a lot of time until you understand what they are asking you.

Considering how hands on learning a language like SQL can be, this course does a lot of info dumping about the theory all at once instead of embracing the practical approach. This makes the course a lot more taxing than it has to be.

The teacher has really good knowledge of SQL and I really respect her for that, but as someone who is not familiar with SQL finds it difficult to give quiz without any side by side practice of the topic

The instructor was clearly reading from a slide without paying a lot of attention to actually 'teaching'. A lot of grammatical errors and flow of sentences made that obvious.

First of all, there is a mistake in examples. I looked on the forum and saw that there were some other people stating this. They didn't bother to edit the 6-minute video. Second, She just reads from prompter. Rarely but she gets stuck while reading. Also, instead of standing still while reading, she sways like a child. It felt like, they are not professional and they don't taken us students seriously

Material was good, but the staff is why I'm giving 1 star. Finished the course and submitted my final assignment for peer review, it has been "in progress" for 4 weeks, this is not acceptable to delay learning progress. Staff should have a way to monitor the assignments time and resolve. We respect your time, please respect ours.

The instructor is hard to follow because of her communication skills. I have to rewatch the videos, and even then I am having a hard time keeping focus on the material because of how many speech errors the instructor makes. I've decided to drop this course and find something similar instead.

Be aware that for many students the sandbox that is necessary for completing the quizzes at the end of each leasson does not work. This is a known issue but so far the lecturer has not commented on this

This course only shows the syntax, but didn't teach how to write. I'm still very confuse about the syntax after taking this course. NOT RECOMMEND

The instructor is really boaring, as if she is reading from a script.

Really disapointed.

I'm fairly proficient in R and wanted to add a database language to my data science repertoire. Most data science jobs ask for SQL so I thought this was the perfect starting point for learning. I found learning the language fairly straightforward, especially because many SQL-type commands are built into R packages (like dplyr). My job has a comprehensive relational database but, I usually use a point and click interface to make queries- now that I'm more proficient I'll start using SQL though. Additionally, I was hoping to pick up SQL before starting my grad program in analytics so I can "hit the ground running" and be ready for classes focused on database management and data engineering. I was able to accomplish this without any question.

I really liked the course, which is not surprising given all of Coursera's data science content is excellent. The final assignment was very thorough and helped put together lots of focused questions you might encounter using SQL as a data scientist. It really helped solidify my learning. For about $60, this was a no brainer for getting started in the language.

DO Slowly, Build up. This is a wonderful course and you will not know when you have learnt so many things. The instructor is wonderful she explains things nicely. The people who have designed the course must be working professionals because Of their depth of understanding of the subject and knowledge.

The most interesting thing about the course is you will learn a few things in a module then try your hands on. you don't even need a laptop to code because they have integrated everything on the Coursera's platform. I have watched most of the videos on my smart phone and submitted a few assignments too.

and the last part of the journey through this course for me is realization. You solve the questions given in the peer graded assignment specially part 2 and for a person who Has been listening the terms like PREDICTION, SENTIMENT ANALYSIS kind of stuff , Learning a few lines of codes in SQL from this course has actually let me do them.

Wonderful course Amazing team

Thanks Coursera

Thanks Sadie St Lawrence
