This presentation provides an overview of the history of big data, its definition, challenges, characteristics, techniques available for analysis and how it supports businesses. It explains that big data is a large and tangled data set from new sources of data that is voluminous in nature, making it difficult for traditional data software to manage. The presentation also discusses the challenges of big data analytics, the characteristics of big data analysis, and the techniques available for big data analysis. Finally, it explains how big data supports businesses in customer interactions and risk analysis.
