MICRO Relational Database Management System - Wikipedia MICRO provides a query language, a database directory, and a data dictionary to create an interface between the user and the very efficient proprietary Set-Theoretic Data Structure (STDS) software developed by the Set-Theoretic Information Systems Corporation (STIS) of Ann Arbor, Michigan
David L. Childs - Wikipedia David L Childs is an American computer scientist noted for his work on his Extended Set Theoretic approach to data base management and cited by Edgar F Codd in his key paper "A Relational Model of Data for Large Shared Data Banks"
Micro DBMS - Academic Dictionaries and Encyclopedias Micro was one of the earliest set theoretic relational database management systems [1] Its major underpinnings and algorithms were based on the set-theoretic model of David Childs of the University of Michigan's CONCOMP (Conversational Use of Computers) Project [2][3][4] It was also influenced to a lesser extent by the relational model made famous by Edgar F Codd, a research scientist at

Database - Wikipedia In 1970, the University of Michigan began development of the MICRO Information Management System [14] based on D L Childs ' Set-Theoretic Data model [15][16][17] The university in 1974 hosted a debate between Codd and Bachman which Bruce Lindsay of IBM later described as "throwing lightning bolts at each other!"
Using Extended Set Theory for High Performance Database Management Speaker Details David Childs developed the extended set theoretic data model in mid-1960’s [IFIP Congress, 1968] and has spent his career enriching it, implementing it, and applying it to practical database problems for many large enterprises He was a confounder of STIS Corp , a database machine vendor, and has taught at University of Michigan and Eastern Michigan University He formed

Extended Set Theory – A Summary - xsp. xegesis. org Extended Set Theory (XST) was originally developed by D L Childs under an ARPA contract to address the limitations of Classical Set Theory (CST) At the root of the problem is the set membership definition of CST, which defines sets and the results of set operations based on a single membership condition: content
XSP Technology Over fifty years ago an ARPA funded research project developed data access operations that allowed any machine-readable data to be accessed and processed in real time These access operations were implemented as a set-theoretic data structure, STDS ARPA envisioned mathematically sound data structures that were interrupt-immune
