# Aggregates

Aggregated values can be calculated at the server level and then viewed by clients. [PARCaggregate](/v1/docs/parcaggregate) can read data from PARChistory or other .NET-type data sources and then calculate daily, hourly, and minute aggregates, as well as a plot-reduced data set. PARCaggregate data are stored as files in shared location. [PARChistory Average](/v1/docs/parchistory-average) is a legacy application that performs a function similar to PARCaggregate. [PARCrollup Server](/v1/docs/parcrollup-server) reads data from PARChistory or other .NET-type data sources and then calculates run-based statistics. PARCrollup Server data are stored in the ctc_config database. Several SQL views are available to help access this data.
