The most common summary measure is the count of records falling in a cell, based on the dimensions defining the cell. Multi-dimensional databases typically contain many datasets. Dataview A Highlander Dataview is a data structure containing multiple datasets, rules for making dimension queries, and data reduction algorithms. A dataview can provide a transparent view to a single dataset or can combine datasets in various ways such as by forming ratios. User-defined calculations using summarized data are implemented by dataviews.
End users interact with dataviews directly, datasets.
Dataview Tree A Dataview Tree is a hierarchical structure of nodes representing dataviews and navigation junctions. This structure visually portrays the subject matter context of the Highlander databases and is an integral part of the database. Navigation nodes organize the subject matter hierarchically. User quickly grasp the scope and nature of the database's information content through this structure. Dimension A Highlander Dimension is an independent variable assuming a finite number of discrete possibilities.
