Abstract: Many interfaces exist for exploring multi-dimensional data, but most are not suitable for OLAP as they do not support aggregation and selection via dimension hierarchies. We introduce an interface for exploring OLAP data via coordinated dimension hierarchies and network views. Three dimension coordinations are identified; progressive, global and result only, for filtering and presenting data. We integrate these with a network pivot that supports joins through an arbitrary relation. We demonstrate with an example web log dataset of site visits organised into time, downloads, visitor address and referrer address dimensions and a network of prior and later visits.
Keywords: OLAP data; user interfaces; dimension hierarchy; website log data; coordinated dimension hierarchies; network pivots; visualisation; site visits data.
