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! By the end of this course, you will have a clear understanding of how relational databases work, and have a portfolio of queries you can show potential employers. Businesses are collecting increasing amounts of information with the hope that data will yield novel insights into how to improve businesses. Analysts that understand how to access this data – this means you! – will have a strong competitive advantage in this data-smitten business world.

L'université Duke est une université de recherche privée nord-américaine, située à Durham (Caroline du Nord). L'université est nommée d'après la dynastie Duke.
Bien que l'université ne fût officiellement fondée qu'en 1924 (ses racines remontent jusqu'en 1838). Fréquemment appelée la « Harvard du Sud », Duke est l'université la plus sélective du Sud des États-Unis.
L'université est membre de l'Association des universités américaines, une association qui, depuis 1900, regroupe les universités de recherches d'élite d'Amérique du Nord.
