In today’s digital world, massive amounts of data are generated every second. From online transactions to social media activity, data is everywhere. Big data analytics is the process of examining large and complex datasets to uncover patterns, trends, and valuable insights that support better decision-making.
As organizations rely more on data-driven strategies, big data analytics has become a critical component of modern business and technology.
What Is Big Data Analytics?
Big data analytics refers to the practice of analyzing extremely large and diverse datasets that traditional data processing tools cannot handle efficiently. These datasets often include structured, semi-structured, and unstructured data from multiple sources.
The goal of big data analytics is to transform raw data into meaningful information that helps organizations improve performance, predict outcomes, and solve complex problems.
Characteristics of Big Data
Big data is commonly defined by several key characteristics.
