hierarchy table

A table in the data model and associated schema with a Dimension Model (DM) prefix. DM tables have a direct correlation to the Network Configuration (NC) tables in Tivoli Netcool Performance Manager - Wireless Component. Each NC table is mapped to a DM table and each row within the DM table takes into account the rehoming of its parent tables. The views that represent the traffic data are joined directly to the DM tables, therefore when we report on data we know the exact hierarchy information of the entity/resource at a particular point in time, without having to query the NC table with a time filter (as is the case in Tivoli Netcool Performance Manager - Wireless Component).
