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.

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.

Great course but there were typos in the assignments that made them hard to understand and the editor wouldn't allow things like INSTR and temp tables.

Good introductory topics. However, not a detailed introduction to any specific queries. This course is for someone who already knows few sql queries.

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 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.

This Course got me started from 0 to 99 .


The project gave me an outline which will help me to set any data with right steps .

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.

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).

Excellent introduction into SQL. The assignments and final peer-review project were great tools to problem solve and practice the skills taught.

I loved the way Sadie delivered important points without taking too much time. She gave just the right amount to details required to get started

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.

Goor refresher or basic start. Personally I found the use of very hepful for this course, more so than the slides.

Loved the course

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.

The course was a great introduction to SQL and the peer reviewing process is a great initiative. The course was well paced and well designed.
