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!...

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

I loved the practices. I learned alot But I think some of them had mistakes... The online visual studio code never worked for me! It might be good to make a video that explains how to work with it.

It's fun thing to learn SQL in the first place, but the instructor seem like just read the script maybe?

But I like the quizzes and coding assignments!

Overall this course is quite good to get a first understanding of SQL. Although i missed some more explanations or examples for complex data analysis.

The overall course was very good, however some question in the tests should be more descriptive. Some of them could be interpreted in different ways.

The course is useful, but in my opinion there must be added more practice during the course and way more examples and explanations in week 3 module.

Some if the query running environments were not working on an iPAD. So it was very difficult to complete get answers. Otherwise this course is good.

Great course, but maybe could use a bit more practice materials between lectures so you keep coding along and learning what you see in the lectures

I think the course is a very good overall complement while learning SQL, one thing I would like to see it some type of a live coding real problems.

Everything was fine and easy to follow. Unfortunately the final exam question's were not really clear and easy to unterstand, so this makes it 4/5.

A great course! You may need to do some outside work to fully grasp certain concepts but this prepared me for my job where im also learning sql.

Overall it is really helpful, especially for the beginner. But I wish there can be more practical guidlines on how to use the SQL in our computer!

Buen curso en general, faltaría clases explicando como instalar sql, ejercicios prácticos que sean realizados en el momento. Igualmente recomiendo

Perfectly prepared. Some tasks in the assignment were boring and tedious (listing number of rows for all tables; getting the non-null attributes).

El curso fue muy bueno, muy claro. Aún así me parece que estaría bueno agregar más ejemplo en los videos, principalmente para las semanas 3 y 4.

A good introduction to SQL with interactive videos. Maybe I will improve the playground a bit so we can practice more queries along the process.

Excellent course for basic SQL knowledge. However, the tests and final assignment are not that easy as taught in the lessons. Highly recommend!

The questions in the final assignment were quite difficult to understand and the overall course took longer than the estimated amount of hours.

The course should have also provided an opportunity of code along with the videos. And output of all the the codes in the video is not shown.
