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
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 was relatively time taking course for me but one who keeps on wins at the end.Thank You professor,duke university and coursera for providing such a wonderful course. Strongly Recommended
Very well structured course. Not that difficult as i thought but it did take me much more time than I expected. You'd better focus on learning for several hours instead of using short time slot.
One of the best course till now I find on Coursera, well structured everything and practice questions made me feel like real life problems as data were from real database of dognition and ua_dillards.
