  • Replicating time-series data values for retrieved supervisory control and manufacturing parameter values in a multi-tiered historian server environment
    Patent number: 8676756
    Abstract: A multi-tiered replicated process database and corresponding method are disclosed for supporting replication between tiers. The multi-tiered replicated process database comprises a tier one (T1) database server computer including a process history database and a replication service. The replication service includes a set of accumulators. Each accumulator is adapted to render a summary T2 database tag data structure from a set of data values retrieved from the process history database for a specified T1 database tag. The replicated database system also includes a tier two (T2) database server computer comprising a consolidated database that includes process data replicated from a set of T1 database servers. At least a portion of the process data replicated from the set of T1 database servers is summary T2 database tag data rendered by the set of accumulators.
