Defines a simple OLAP Result and Metadata.

Overview

The OlapModel provides access to the {@link com.tonbeller.jpivot.olap.model.Result} of a query. It does not specify the query itself (e.g. what data will be displayed).

The interfaces in this package define a minimal OLAP result. The definitions are independent of an implementation like Mondrian or JOLAP. It only defines what is necessary to display the result to the user.

OLAP Result

To support "ragged hierarchies" or "parent-child hierarchies" no assuptions are made regarding the number, ordering or hierarchy of Levels instances. See Microsofts definition of Parent-Child Hierarchy
