Abstract: Set-Theoretic Information Retrieval from Mega-Byte Previous HitDataNext Hit Bases

D. Z. Briggs, L. I. Briggs, A. B. Coconower, J. D. Lusk

At the Subsurface Laboratory, University of Michigan, the Set-Theoretic Previous HitDataNext Hit Structure (STDS/IV) Information System has proved useful for Previous HitprocessingNext Hit subsurface geology Previous HitdataNext Hit files of mega-byte dimensions: The Michigan Basin Well History Control System (WHCS), The Subsurface Laboratory Inventory Files, and The Stratigraphic Previous HitDataNext Hit Files.

STDS/IV is particularly effective for information Previous HitprocessingNext Hit using set-oriented formats and procedures, integrating and comparing of Previous HitdataNext Hit derived from two or more differently structured files, and derivation of information and construction of Previous HitdataNext Hit sets for analytic procedures such as mapping, geostatistics, and management decision functions.

Information Previous HitprocessingNext Hit includes transformation of Previous HitdataNext Hit into operational sets, sorting, keying, retrieving, and updating set components, extracting information using set functions, enumeration of specified quantities, and report generating. Thus the STDS/IV system provides a Previous HitbasicNext Hit set of operations derived from mathematical-set theory, and routines that support editing, updating, retrieval of Previous HitdataTop, and generation of reports.
