Replaced by DiversityDescriptions (DeltaAccess 2.0). A SQL interface to DELTA, the Description Language for Taxonomy, implemented in Microsoft Access 97, 2000, and 2002 (= XP). DeltaAccess can be used in 3 ways: a) You can use DeltaAccess simply as a module to import DELTA coded text files into a database of your choice and then write an independent application for that database (e. g. a web interface). b) You can keep your data in DELTA coded text files, and use DeltaAccess as a one-way import tool to analyze your data (incl. cross-tabulations, and charts), print form sheets to edit your data off-line, or to generate dynamic html/www output. c) You can use DeltaAccess as the central data repository around which your work is organized. You can thus make full use of advanced editing functions of DeltaAccess, like the multiple item editor.
