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 is very beginner friendly. The concepts were explained well. Additional Reading materials were provided too in every module. In-video quiz, practice quiz and coding practice questions made it easier to revise concepts of each module.

For me, it was an excellent course to have a first approach to the software. Some exercises or assignments are difficult compared to the level of the course; however, you should make your own research and give your additional effort to solve it.

The syllabus was well-thaught and the content amount was exactly what it needed to be. The additional readings provided in the course were really helpful. It would be even better to privide more examples in between teaching different functions.

The only thing that i will suggest is adding the output table for many codes that was shown. For the ones which was shown it was pretty easy to understand the whole idea. Other than that course was great and final assignment was really helpful.

I feel that I established a good knowledge base and added new elements in the environment of the related select statements, both with the design and mainly with the data analysis to obtain new and useful information from them.

Excelent, Thanks.

Very good course to get the basics of SQL language and main principles. After this course and some "google" help you will be able to write really complex SQL queries. Course gives you the base and then it is only practice, practice, practice.

Easy pace course, good video tutorial but you also need to do learning from other available resources in order to fully understand the concept. I am glad I enrolled and learned the SQL.

Thank you very much, looking forward for another course.

This course is very good as an introductory one is SQL. The instructor explains everything very clearly, whereas quizzes, coding assignments, and the final project are very helpful in order to apply the skills you've learned watching videos.

Very useful course. The videos are short so they don't need much effort to finish. They are easy to understand and well explained. The girl talks very fluency and slowly so it's easy to understand and also she is pretty so it´s nice to see.

Very help full, fullfiling every gaps and strenghthens the knowledge around coding and analyzing data. The tests are competitive and really need to focus. Lastly, yoy need to search on your one some things if you are new in coding like me.

A very good course for them who are new to datascience and SQL. Course divided into modules was very helpful. Pace of course was evenly distributed throughout the course. Only problem with the course was few more problems can be discussed.

This course is very very useful! And for people who say they didn't provide us with a platform to work with our queries against the DATASET inside the course. JUST open the sandbox lab inside Coursera to work against the Chinook Dataset!

I enjoyed this course very much. There are a few issues that need to be addressed, but if you can overlook her occasional stumbles, she is effective and entertaining and the material was engaging and held my interests which is NOT easy.

The course provided a nice introduction to the topic and proper SQL coding exercises. The grading scale of the peer graded assignment is however to easy and almost everyone will pass even if their deliverables are of the worst quality.

I enjoyed the course and learned a lot of fundamentals. There are some gaps about notation and an occasional unclear question that would most likely be addressed in a live class. Otherwise, this format worked well for this information.

It's amazing. And the last assignment was very challenging. We create a query to support the data analyze process. And we also have chance to see other participant work on it. It' a great experience. Thank you for running this course.
