TLDR
The DETHERM as discussed by the authors is a data bank for physical property data of chemical compounds and mixtures, which allows the retrieval of literature data, the algebraic manipulation of retrieved data, data calculations and estimations, data analysis, and connection with data processing systems.
Abstract
DETHERM, eine Datenbank fur thermophysikalische Daten chemischer Verbindungen und Gemische fur die Stoffdatenversorgung von Ingenieuren, wird beschrieben Damit sind Recherchen nach Literaturwerten, algebraische Datenmanipulationen und -umformungen, Datenberechnungen und -schatzungen, Datenanalysen sowie die Verknupfung mit Stoffdaten verarbeitenden Programmen moglich In der Datenbank sind numerische und bibliographische Daten gespeichert, die Art der Daten und Stoffe wird durch „Tags” gekennzeichnet A physical property data bank for chemical engineering DETHERM, a data bank for physical property data of chemical compounds and mixtures as required by chemical engineers is described, which allows the retrieval of literature data, the algebraic manipulation of retrieved data, data calculations and estimations, data analysis, and connection with data processing systems In the data bank both numerical and non-numerical data are stored, data and substances being labeled by „tags” which characterize the kind of stored data and substances

Die Versorgung von CORIS® mit Stoffdaten

TL;DR: The database contains thermo-physical properties of the corrosive media and allows the search of the data included in the database and the update of data by the user himself and a graphical user interface allows the simple use of the system and the exchange of data with the other system components.
