In Data Analytics, our class explores how to analyze business data to enhance firm competitiveness. We have learned about the Analytical Data Store, which is the foundation of business intelligence. We also covered the topic of association rule mining, which is a form of analysis of Big Data to predict the occurrence of certain transactions and events and uncover patterns. Furthermore, Clustering and Segmentation is another form of Big Data analysis companies use to understand and summarize data.

Big Data in Today’s World: VISA

Visa experienced the challenge of combating credit card fraud while maintaining a seamless service to customers. Customers had complained of payment rejections on vacations and business trips. However, by using advanced tools, Visa was able to analyze up to 500 unique variables in real time when analyzing risk of transactions. By performing clustering and segment analysis, Visa was able to determine the difference between a fraudulent act and when a client was on a trip. Big Data has enabled Visa the potential to prevent $2 billion of fraudulent payment annually.
