Amount of information is overwhelming & growing

Alternative: Domain-specific search engines allow more efficient searching

Foil 21 A Comment on the Use of Databases in "HPCC"

From CEWES Year 2 Summary of NPAC Activitie CEWES End of Year 2 Review Vicksburg -- Feb 24-26 98. *
Full HTML Index
Historically, HPCC field has not made much use of commercial software. Especially database systems.
Elsewhere, databases increasingly viewed as "the right way" to do many things. May require slightly larger initial investment (software, training...), but cheaper over entire life cycle.
NPAC currently runs four Oracle servers. Question is not whether to add more, but how many more and if production or development or teaching?
Lack of clear RDBMS strategy at CEWES MSRC limits these WWW/database projects & possibly other creative and useful applications
