MIRACLE: A Time-oriented Data Validation and Analysis System for Clinical Research^[*]

Summary

MIRACLE is a medical information system designed to validate and analyse time-oriented data. The chronological patient database is composed of user-defined repeating groups stored in numerically coded character records of variable length. A flexible query language gives access to semantic validation, cross-sectional and mixed-longitudinal analysis. The main application is at present a large hospital-based tumor register.

MIRACLE ist ein medizinisches Informationssystem fur die Validierung und Analyse von zeitorientierten Daten. Der chronologische Datenbestand eines Patienten besteht aus benutzerseitig definierten multiplen Satzarten, die in numerisch codierten Siitzen variabler Liinge gespeichert werden. Eine flexible Abfragesprache ermoglicht eine semantische Validierung sowie die Analyse von Querschnittuntersuchungen und gemischten Liingsschnitt-untersuchungen. Die wichtigste Anwendung ist zur Zeit ein groBes klinisches Krebsregister.

Key-Words:
