A family of integrated systems has been developed within Digital's enterprise management architecture (EMA). The product called DECmcc is part of a larger EMA implementation, which consists of both an enterprise management director and a framework for developing consistent and integrated management solutions with EMA. An object-based framework provides time-oriented dispatching of operations and serves as a foundation for modules supporting past, present, and future time views of managed objects. Fully integrated modules implement a conceptual diachronic object-base that allows time-oriented, object-based modeling of resources. To maintain the historical part of this diachronic object base, DECmcc provides comprehensive facilities for collecting, processing, purging, archiving, and exporting historical attribute data. The managed object instances, for the existing objects that need to be globally and directly accessible, are stored using DECdns, i.e., essentially DCE/CDS. The historical data are stored on the domain basis locally. Recorded historical data and 'live' enterprise data can be exported to a relational database in a uniform fashion for any combination of past time, current, and future data.<>
