Big data is a term that describes large volumes of structured and unstructured data that are too complex to be processed by traditional data-processing software. The data can come from numerous sources and in various formats, such as texts, videos, social media posts, or purchase transactions. Big data is not just about the volume of information, but also about the technologies and analytics that make sense of this information to support decision making. Big data analysis can reveal insights about behaviors, patterns, and trends that can be used in areas such as strategic planning, predictive analysis, and improving customer experience.
