What is the definition of big data?

The definition of big data is characterized by extremely large, complex, and variable data sets. This definition captures the essence of big data by highlighting three critical dimensions: volume, variety, and complexity.

Volume refers to the immense amounts of data generated by various sources, including social media, sensors, and transactions. Variety indicates the diverse formats this data can take, ranging from structured data in databases to unstructured data like text, images, and videos. Complexity refers to the challenges associated with the processing and analysis of such diverse data, which often involves sophisticated algorithms and infrastructure to derive insights.

This understanding is fundamental in Cognitive Project Management for AI, as managing and leveraging big data effectively is crucial for developing AI solutions. Other definitions presented do not encompass the full scope of what constitutes big data. Data sets that do not require special processing, for example, refer to simpler data sets rather than the complex nature of big data. Similarly, data sets that can be processed in real time do not necessarily indicate the size or variety characteristic of big data. Finally, simple and structured data sets fall short of capturing the complexity and breadth associated with big data. Thus, the chosen definition accurately reflects the contemporary understanding of big data in a technological context.
