To approach this prompt, I will restate the task and then break down the concept piece by piece. Explain what big data is typically understood to be, along with common defining characteristics.

First, consider the core idea: big data describes data that is so large or complex that traditional data processing tools struggle to capture, store, manage, and analyze it efficiently. This encompasses not only size, but also challenges in variety (different data types and formats), velocity (speed of data generation and ingestion), and sometimes veracity (uncertainty in data quality) and value (the usefulness of the insights derived).

Next, examine the phrase "extremely large and complex sets of data": this highlights two aspects. The data volume is substantial—far beyond what simple databases were designed to handle. The complexity arises from multiple sources, disparate formats, and the need for advanced processing techniques such as distributed computing, parallel processing, and scalable storage.

Then, reflect on the part about traditional data processing tools: conventional systems (like single-node relational databases and basic analytics) can become bottlenecks or inadequate when faced with the scale and speed of big data. This motivates the use of frameworks and technologies designed for big data, such as distributed file systems, map-reduce paradigms, and cloud-based storage and compute resources.

In terms of the commonly cited characteristics, the three Vs (volume, velocity, variety) are central. Volume refers to the sheer amount of data; velocity to the rapid generation and need for real-time or near-real-time processing; and variety to the diverse data types (structured, semi-structured, and unstructured data such as text, images, audio, video, logs, sensors).

Additionally, some definitions expand with veracity and value. Veracity addresses data quality and reliability, while value emphasizes deriving meaningful business insights from the data.

Putting it all together, the given statement captures the essence of big data by describing its scale, complexity, and the inadequacy of traditional tools, and by alluding to the key characteristics (high volume, variety, and velocity) that commonly define the concept.

If you were judging potential alternative phrasings, statements that minimize the scope to small datasets, or that claim big data is only about volume, or that ignore the need for advanced processing or the multi-faceted Vs, would be deficient definitions. A complete, accurate definition aligns with the idea of data that is too large or too complex for standard methods and is characterized by speed, diversity, and scale.
