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!

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.
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
A very well designed course with no prior knowledge assumed. The discussion forums are very lively and queries (no pun intended) are responded to fairly quickly. A great option who wants to learn sql.
Excelente curso, disponible en múltiples idiomas. El acceso a las plataformas para poder practicar es excelente. Los ejercicios van subiendo en dificultad, permite el aprendizaje progresivo.
