Both the publication process and the underlying technical architecture are described with a focus on design choices (e.g. the adoption of RDF Data Cube Vocabulary for multidimensional data(More)
Questo lavoro descrive alcuni principi progettuali e un modello innovativo per data warehouse statistici su Web. Questo tipo di sistema si basa su un modello di rappresentazione per tavole statistiche, specificamente pensato per renderle accessibili e navigabili dal Web. Il sistema tiene traccia dello stato della navigazione, la quale è basata su una(More)
