Tipi di connessione in Power BI e modelli compositi

Il termine "modello composito" in Power BI è stato utilizzato, inizialmente, per indicare un modello in cui le connessioni Import e DirectQuery risiedevano nello stesso set di dati. Successivamente, con l'introduzione di Direct Query su Analysis Services e Power BI Dataset, è stato nuovamente utilizzato il termine "modello composito" per indicare quest'ultimo sviluppo. Ora le connessioni Live possono convivere con le connessioni Import e DirectQuery in un unico modello, usando il modello locale di Direct Query su Analysis Services e Power BI Dataset. La mia sessione si occuperà di: 1) chiarire la differenza tra una connessione in Import, DirectQuery, Live e Direct Query su Analysis Services e Power BI Dataset, 2) chiarire i casi di utilizzo di ognuna delle opzioni appena citate, individualmente, 3) mostrare esempi di ognuna delle opzioni, 4) mostrare un progetto in cui Import, DirectQuery e Direct Query su Analysis Services e Power BI Dataset convivono e 5) elencare limitazioni, pro e contro di ciascuna opzione.

Power BI Dataset, Dataflow, Datamart: which to choose and why?

The recent introduction of Power BI Datamarts, still in preview, has increased the options available to the designer and the business user. There is now some confusion on this subject as to how to make a wise choice, the pros & cons of each and the related limitations and differences. But mainly, the point is that there is the belief that these 3 structures are mutually alternative which is not the case (a dataset is a must in anycase). So in my session I would 1) make a clear definition of each of the 3 entities, focusing on the fact that a dataset is mandatory in Power BI in any case and what a PBI dataset is 2) explain the key usage cases of each of the three with examples made in real time in fronte of the audience 3) discuss with the audience how to make a choice, licensing/workspace needs and the related limitations.
