Aggregated values can be calculated at the server level and then viewed by clients. 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 is a legacy application that performs a function similar to PARCaggregate. 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.
