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!...

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.

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.

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.

After the 2nd week, the instructor just introduces new concepts and does not explain the working of the algorithm. Also, more or less the video length should increase and more examples should be discussed.

Overall the course is great !!!!

The biggest issue is the lack of practice . They try to stack on lot of things and ask a quiz at end of a week which is the only mean of practice. Coding doesn't word that way atleast could have given some practice after every lesson.

Quizzes and assignments require a lot of knowledge not actually covered in the course forcing you to search for information elsewhere.

Questions are not clear in many tests creating incorrect answers which are not of the learners fault.

The course teaches good information but many of the quizzes involve information that was barely (or not at all) covered in the lessons. It would help if they fixed this or were at least more active in the forums to answer questions.

Helpful information but the instructor was just very awkward and pretty distracting. I get that she's reading off a script but it just didn't seem like any of it was rehearsed at all and it was sometimes difficult to follow her.

There is much this course lacks. Such as proper user guide when uploading assignments as well as more example problems throughout the lecture. This will only expand on the user friendly envirnemnet and help leaners achievemore.

The course is not bad but, and this is a big but at least for me, they do not provide DBMS to practice with and no practicing material. Also, some of the links provided to get more info about different topics is way outdated.

The quizzes and readings were helpful. The lectures were helpful for some problems and for some they were just too long without containing multiple examples. The peer review assignment was the hardest out of the whole course.

This course is okay but I feel like they need more practice queries not just a test and you never got to try it before also the questions need to be better explained. Other than that I feel like I did learn the basics of SQL

I learned some basics about SQL and enjoyed it, but I think there wasn't enough practical instruction about how the code is used. It made it hard for me to figure out how to get the data I was asked for in the assessments.

This course gave a really strong overview but some of the questions in the assignments were ambiguous/needed clarification. From the discussion boards this has been the case for quite a few years without being addressed!

The course vidoes were really nice.

The wording of the exercises is frequently confusing, especially in the peer-reviewed assignment. Many question cannot be answered with the tools provided (i.e. inference, correlation).

THERE IS BUG IN YOUR PEER ASSIGNMENT SUBMISSION THAT THERE IS NO "SHARE LINK" OPTION GIVEN AND IN YOU HAVENT MENTIONED ANY WAY TO DEAL WITH THIS PROBLEM. IT IS REALLY FRUSTATING AND THIS PROBLEM SHOULD BE RESOLVED.

Theoretically it is best program, but for practice and use of chinook was not well explained. I find to complete last assignment very difficult where there was not preparation for such a huge task for a newbie.

Course materials are good, but wish they provide the actual SQL code in answers to quizzes and assignments. Simply providing whether my answer is correct or not is not enough for me to know what I did wrong.

course was really good and understandable for some beginner like me but at same time I think that more coding exercises were required

ONCE AGAIN THANK YOU FOR IGNITING THE INTEREST TOWARDS DATA ANALYSIS IN ME

The general structure and idea of the course was good; however, there were many times when the script/questions were worded badly and this was sometimes an issue when it came to understanding the content.

No practice examples at all. Videos have only theorethical queries without results, so you can`t see how it works on practice. Reference to SteckOverFlow is awesome. Why should I pay money for nothing?

I thought that the instructor could have gone over the material detail by showing real time examples herself while in SQL. This would have been super helpful. Also, the quizzes were much too difficult
