Peer reviewedDatta, Anindya; Viguier, Igor R. – Information Systems, 1997
In environments where the state of the system changes rapidly, such as stock trading, air traffic control, network management, and process control, databases have been proposed as the platform to develop automated control systems. Information in such systems consists of "updates," reporting on the state of the environment and…

Peer reviewedWisniewski, Janusz L. – Information Processing and Management, 1986
Discussion of a new method of index term dictionary compression in an inverted-file-oriented database highlights a technique of word coding, which generates short fixed-length codes obtained from the index terms themselves by analysis of monogram and bigram statistical distributions. Substantial savings in communication channel utilization are…
