NDLI: Reality check: a case study of an EII research prototype encountering customer needs

Content Provider	ACM Digital Library
Author	Simon, Eric
Abstract	Le Select is a research prototype of an EII (Enterprise Information Integration) system (also known as a mediation system), which was developed from 1998 to 2001 at INRIA (France). Le Select was then transferred to a start-up company named Medience, which was purchased in 2005 by Business Objects. Under its new brand, the EII system now called "Data Federator" is a master piece of Business Objects' Enterprise Information Management (EIM) offering. During this period of nearly ten years, the EII system has been rewritten almost three times, not only for industrializing its code, but mainly because the system was confronted to customer needs that required modifications in order to address functional needs that were not anticipated. The aim of this presentation is to review these main transformations of the system and relate them to Business Intelligence application requirements. We emphasize a few problems such as designing complex views, data cleaning, and query optimization strategies for "narrow" and "mega" queries. The presentation makes extensive use of customer cases to illustrate our purpose. We conclude with a list of open issues.
