Granularity

Granularity refers to the level of detail or the size of the smallest units within a dataset, system, or process. Think of it like zooming in or out on a map: fine granularity shows detailed streets, while coarse granularity shows only cities or regions. In data, finer granularity means more specific information (e.g., individual transactions), whereas coarser granularity means aggregated data (e.g., monthly totals). Choosing the right granularity depends on the analysis needs—more detail can provide insights but may increase complexity and processing time.
