Interactive access to ascendants while navigating hierarchical dimensions

Abstract

A method for controlling data from a data hierarchy with enhanced interactive access to ascendants while navigating in hierarchical dimensions of a materialized view renders a segmented band along each axis of a grid layout using a different background style for each level identified in the hierarchy. Heading titles for parents at a same visual hierarchy use a same background style and fill a space between a heading and respective child levels. When user traversal axially causes a heading title of a parent node to become invisible from a node headings bar in the segmented band of a respective axis, the heading title is promoted to a matching segment. An interactive control is rendered adjacent to the promoted heading enabling direct navigation to that parent node. Invoking the interactive control renders the visual hierarchy with the heading title of the parent node shown first in the node headings bar.
