The DeepSee Model
This chapter discusses the key elements of the DeepSee Model — the elements that underlie DeepSee
pivot tables. It discusses the following topics:
• An introduction to the terms
• Cubes and BI-enabled classes
• Dimensions
• Filtering
• Subject areas
• Detail listings and listing fields
• Measures and computations
3.1 Introduction
Because the DeepSee concepts are interrelated, making it impossible to discuss each concept without
reference to the others, it is useful for us to start with several working definitions:
• A dimension is a construct that we use when we group the source data. A dimension (such as
Country) has members. Each member, in turn, corresponds to a specific set of records in the source
data. We group the records separately for each member.
• A measure is a number or date that is based on numeric or date values selected from the source
data. A measure aggregates those values and represents them with a single value, which is shown
in a pivot table.
• A listing field is a source data field, with a user-friendly name assigned to it if necessary.
