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).
