Pivot Tables and Hierarchies

Ronda StemachEDM GroupApril 8, 2013

Today’s Two Topics

1. Pivot Tables• Data Summarization Tool• Change of Perspective – View Data Different

Ways

2. Data Hierarchies• Cascaded Data, Summary to Detail• Created using business-specific logic

Humboldt’s Hierarchies

Level Based Hierarchy

• Fixed Number of Levels

Special Level Based Hierarchy:Ragged

• Not all “parent” members have “child” member

Special Level Based Hierarchy:Skip-Level

• Not all “child” members have a direct or immediate “parent” member

Special Level Based Hierarchy:Mixed Example

Value Based Hierarchy• Not often used• Based on Values within the same table• Classic Example – Org chart

OBIEE Graphs

• A graph view displays numeric information visually, which makes it easier to understand large quantities of data.

• For displaying a single data value, a gauge is often more effective than a graph.

• A gauge usually plots one data point with an indication of whether that point falls in an acceptable or unacceptable range.

• Gauges are useful for showing performance against goals.

Types of Gauges

• DIAL - Shows data with one or more indicators that point to to where the data falls within predefined limits.

• HORIZONTAL BAR - Shows data using a horizontal bar that changes color to indicate whether the data is within predefined limits. The inner rectangle of the horizontal bar shows the current level of data against the ranges marked on an outer rectangle.

Types of Gauges, continued

• VERTICAL BAR - Shows data using a vertical bar that changes color to indicate whether the data is within predefined limits. The inner rectangle of the vertical bar shows the current level of data against the ranges marked on an outer rectangle.

• BULB - Shows data using a circle that changes color to indicate whether the data is within predefined limits. Useful to display status, not a specific value or threshold.
