Trends and Scale-Up for Data Administration.
Arnon S. Rosenthal, Leonard J. Seligman · 1997
The application development lifecycle is undergoing several unifications that, together, will rescue conceptual modeling from the wilderness. At the same time, advances in data warehouses and middleware are removing some of the software barriers to large, multi-organizational databases, creating new data administration challenges. The increasing scale and complexity of our systems identify new grand challenges to data administration research; we discuss two of these, in some detail: the administration of multi-tier schema, and exploiting legacy or foreign data during the development of new application schemas. We illustrate these issues with examples taken from the United States Department of Defense (DOD).
