課程概述

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.

Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

Clear and interesting course. I would have preferred to have practice exercises earlier. Not just at the end of each week, but after the specific explanation video.

Sadie was an excellent instructor. She was engaging and professional. I should have taken this course before jumping into the SQL / Python course in Data Analysis.

I think this course gets its purpose right for the starters, but you'll need to learn more to progress in the field of data acquisition. Good course, nevertheless.

This course builds blocks to work with SQL. After week-2 it requires logical thinking to solve assignments. The lectures and the way it has delivered ain't boring.

Al final se me complicó mucho el ánalisis de datos dado que mi experiencia era nula en ese ámbito. Creo que podrían recomendar bibliografía básica para ese rubro.

The course content was good and educative. The quiz and coding exercises are challenging to the point of enforcing your brain to register what you have learned.

Great class. The time estimates I thought were understated especially for week 3 and week 4. Budget yourself plenty of time for the 2nd half of the course.

Cool course! In a plain language about such an exotic subject if you are about to find yourself in something not specific and new as myself. Hardly recommend!
