This course is an introduction to how to use relational databases in business analysis. You will learn how relational databases work, and how to use entity-relationship diagrams to display the structure of the data held within them. This knowledge will help you understand how data needs to be collected in business contexts, and help you identify features you want to consider if you are involved in implementing new data collection efforts. You will also learn how to execute the most useful query and table aggregation statements for business analysts, and practice using them with real databases. No more waiting 48 hours for someone else in the company to provide data to you – you will be able to get the data by yourself!

Лучшие отзывы о курсе MANAGING BIG DATA WITH MYSQL
Excellent course for beginners looking to be able to utilize SQL directly or even understand how SQL works so requirements can be gathered with greater detail and why that detail is needed.
thank your for accepting my in the course i really liked studying it i suffered with some difficulties but i survive the course was very good but getting harder by week 4 but interesting
very detailed introduction of SQL. The only thing is that there could be more videos introduce different functions instead of writing documents as materials. Other than that, it's a great class
It's hard to understand the data that given for quizzes but the teaching of professor Jana is really amazing.when i ask questions in discussion forums there was no tutor to help you out soon.
