ROMMII (referential ontology Meta model for information integration) architecture for dynamic restructuring of the DWH data models
Résumé
Semiconductor industry (SI) is facing difficulties in data/information integration while deploying DFM (design for manufacturing) methods for an efficient root cause analysis. Recent IT developments have resulted in the availability of huge volume of data across multiple dimensions, however we are still unable to fully exploit data for a knowledge discovery. The database technologies have addressed platform heterogeneity and efficiency BUT unstructured data model evolution, ontology issue, missing links and the risk of failure of a single source and/or multi source data analysis tool are the key limitations towards an efficient root cause analysis. In this article we present a software framework supported with ROMMII architecture to address these key challenges and ensure dynamic restructuring of the data model against varying needs to ensure the availability and access of every single data element without any risk of the tool failures.
