Big data is a data science that deals with analytics, data mining, and extracting information from a data set that is too large or complex to be dealt with by traditional data-processing software.

The term big data can also refer to the use of predictive analytics, statistical analytics, statistical modeling, or other advanced analytics methods that use electronic data from a data set, regardless of the size of the data set.

The ecosystem of big data can be characterized as:

Applications that benefit from big data analytics include: health care, banking, education, media, Internet of Things, economic productivity, crime, security, and natural disaster and resource management.

Big data matters that require expert witness services typically involve intellectual property, criminal, data analysis, or cyber security.
