The 2015 ITGS case study for the paper 3 exam is entitled Asociación de Supermercados Independientes (ASI) – An investigation into Big Data. In the case study scenario a group of supermarkets are investigating the possibility of using loyalty cards and other systems to collect data about their processes and their customers, and using Big Data analysis techniques to leverage that information for a competitive advantage. To successfully answer questions on the paper 3 exams students will need to understand the general concept of Big Data as well as how it can be applied to supermarkets and the ASI group. Here are seven videos that explain what Big Data is and how it can be used:
