Big data is the technology which collects transforms the huge data which is in a unstructured manner.
Business Intelligence is the technology which uses the transformed and loaded historical data to get or create the reports.
Business Intelligence involves data driven decision making. It is a set of methodologies, process, theories that transform raw data into useful information to help companies make better decisions.
Big data on the other hand is a broad based term, which is a set of tolls and techniques that are used to collect huge volumes of data both structured and unstructured.
Hi, Tony.Per my experience, Big Data has much more to do with the nature, the source of the data (apart from its huge volume) and the process to extract it from that sources. Business Intelligence has much more to do to what we do with these data, captured from those sources and how to deal with this new type of data and tools to analyse it (Hive, Pig, Hadoop, R, Matlab, etc.).
Big Data, very simply defined, is collectively the tools, techniques and technologies to identify, capture and process the volume, velocity and variety of the flow of digital data.
Business Intelligence is the ability to create value (better-faster decisions, etc.) from the volume-velocity-variety of data. Think of BI as a subset of the more overarching concept of Big Data.
