Modeling of an Object-Oriented Datamart for Knowledge Discovery in Multimedia Metadata Joaquim Felipe and Marina Teresa Pires Vieira   View Paper (PDF)   Return to Data Warehouses Abstract This paper describes the modeling of a data mart designed for use as a data repository in the knowledge discovery in data bases (KDD) process applied to a multimedia metadata environment whose data structure is based on the MHEG-5 standard. The data mart design uses the features of the original repository which are meaningful for the KDD process. The typical data warehouse structure was adapted to the object-oriented multimedia environment, and a structure that is both homogeneous capable of integrating information from different sources and objective providing specific content and functionality for analysis was generated to support the data preparation process before the data mining operation.
