О курсе

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 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, I thoroughly enjoyed it! The videos are crisp and to the point. The assignments are challenging which is good because at the end of the course you would get pretty comfirtable using SQL for data analysis.

This course is excellent! I loved that I could test queries and be creative. I really got to learn what I could (and couldn’t) do with sql. I definitely feel more confident with putting SQL as a skill on my resume now.

This course is very suitable for novices to get started, step by step, from the shallower to the deeper, and the course supporting exercises and homework are also great! The course time is also reasonable! Super cool!

Great course on the fundamentals of SQL for data analysis. I particularly enjoyed the last assignment. I feel that I have learned a lot (though I also needed to complement it with other SQL courses). Thank you Sadie!

Amazing course!

However, I felt that it could be improved by placing after each lesson some exercises related to the concept just taught, instead of teaching lots of concepts and then assessing them at the same time.

This course was excellent for me, learned small things that I did not know existed but that are so powerful when making the querys. Help me optimize the queries, and I will follow the advice: "think before writing"

I liked this course a lot. Sadie explains well and the amount of exercises from easy to less easy and more difficult, makes you practice and internalize the concepts. Although more practicing is required of course.

This is a great course for those without any prior programming SQL knowledge. It helps if you already have experience working with datasets and if you already know how to program in another language (i.e. SAS, R).

I find this course very helpful, prior to this course I used to think its just a language to query the data from Data base but now I have realized its importance after seeing how it can be helpful for data science.

One of the best courses for learning SQL. It could, however be better if they provided access to the database so I could practise on it, but it was still great and I learned the basics of SQL for Data Science.

Very good intro course to SQL. Enjoyed the instructor's presentation and enthusiasm for SQL. Covers SELECT statement and JOINs plus some common functions MIN, MAX, COUNT, etc. Good baseline for retrieving data.

Good course to learn a overall high-level view of SQL. However, to get the full grasp of SQL you need to practice SQL from external resources as well. This course explains SQL commands in a brief and concise way.

Great Course. Very well structured and comprehensive. The participants get a good grasp of what a database management system is, how it the data are stored in it and how SQL is used to extract data out of it

This course is well designed and Sadie did a good job of pacing/explaining. It touches various SQL concepts. The best way to learn SQL is to use this course but keep google handy for any additional research.
