MDBE: Automatic Multidimensional Modeling

Provided by: Springer Healthcare
Topic: Big Data
Format: PDF
In this paper, the authors present MDBE, a tool implementing their methodology for automatically deriving multidimensional schemas from relational sources, bearing in mind the end-user requirements. Their approach starts gathering the end-user information requirements that will be mapped over the data sources as SQL queries. Based on the constraints that a query must preserve to make the multidimensional sense, MDBE automatically derives multidimensional schemas which agree with both the input requirements and the data sources.
