| Zusammenfassung: | A computing device includes a processor and a medium storing instructions. The instructions are executable by the processor to: receive a database query for an approximate aggregation of a numerical value of a plurality of records, wherein each record includes the numerical value and a filter value; in response to the database query, determine a count of records that have filter values within an importance threshold associated with the database query; and determine the approximate aggregation of the numerical value based on the count of records and the importance threshold associated with the database query. |
