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!...

SQLite did not offer many features required to answer the questions. Would recommend a higher version of sql to help do more analysis and answer quiz questions still better.

Buen curso, lo recomiendo si deseas empezar desde cero, aprendes paso a paso las herramientas que te proporciona SQL. Solo me hubiera gustado que amplíen con más ejemplos.

Good relationship between theory, practice and fundamentals of SQL and Data Science. I would say some basic knowledge on programming will totally ease the learning process.

Easy and Understandable, basic knowledge in SQL, but could be better if the standard answers for the practice quiz and coding assignments could be provided by the teacher.

Takes some time to complete. The assignments are not trivial. It would help if the peer-review process would be somehow more easily accessible (graphical etc.) to grading.

I really enjoyed learning SQL. Ms. St.Lawrence's videos were clear and precise. I also liked that we had to complete the quizzes and assignments by the end of the week.

excellent course, but I recommend having a general understanding of SQL, as it is a quite intensive course and it can be difficult to understand all the material quickly

A very informative course which everyone should learn.

It starts with basic topics and progresses towards advance parts.

Solving the assignments and quizzes help a lot.

everything was good. However, the assignments question should have been changed as it seems to be the same and there should be a proper evaluator to do its evaluation
