aggregare

Aggregare is a verb used in Italian to mean bringing together or assembling into a whole. The word derives from Latin adgregare, formed from ad- “toward” and grege/ greg- “flock,” reflecting the notion of gathering items into a group. Cognates appear in other Romance languages, such as French agréger and Spanish agregar, though usage and nuance differ by language.

In Italian, aggregare is commonly employed in technical and analytical contexts to describe combining several items, records, or streams into a single set or summary. The related noun aggregazione refers to the process or result of aggregation, while aggregato and aggregatore denote an element produced by or performing the aggregation.

In computing and data processing, aggregation denotes the operation of summarizing data. An aggregation function (for example, sum, average, count) is applied to groups defined by keys; databases use aggregate queries to compute metrics by category, and data pipelines deploy aggregators to reduce data volume and generate summaries.

In information services, an aggregator is a service or software that collects content from multiple sources and presents it in one interface, such as news or product aggregators. Beyond technology, aggregation also appears in statistics and economics as the process of forming higher-level summaries from lower-level units to support analysis and decision making.
