OLAP Hierarchy

Overview

The OLAP Hierarchy page maintains hierarchy definitions for analytical tables. Use it to select the schema and table, name the hierarchy, describe it, and arrange the table columns that make up the hierarchy levels.

Function

Schema selects the data mart schema. Table lists the available analytical tables for the selected schema and defines which columns can be used in the hierarchy.

Hierarchy name is the required name shown in the navigation tree and Hierarchies list. Description documents the purpose of the hierarchy.

The hierarchy columns grid defines the ordered levels. Column selects a column from the chosen table, SeqNr controls the level order, Name provides the level name, and Description documents the level.

When a new hierarchy column is added, AnalyticsCreator assigns the next sequence number. Save requires a hierarchy name and table, stores the hierarchy, refreshes the navigation tree, and reloads the page. Cancel closes the page without continuing the current edit.

Access

Open an existing hierarchy from the Hierarchies branch in the navigation tree, or double-click it in the Hierarchies list. Use Add hierarchy from the Hierarchies branch, or New from the list, to create a hierarchy. When opened from a table context, the table can be preselected.

How to access

Data warehouse -> Hierarchies -> [table] -> [hierarchy] -> Edit hierarchy, or Data warehouse -> Hierarchies -> Add hierarchy.

Toolbar

Data mart -> Hierarchies, then double-click a hierarchy or choose New.

Diagram
