Chemical engineering basic physical property database system analysis and structural design

Abstract

 Based on the DBTC database system proposed by the American CODESYL organization, this paper dissects and analyzes the basic chemical physical property data, and proposes a network data structure model among the basic chemical physical property data. Based on this structural model, a retrieval-oriented system is designed. A functional large-scale chemical basic physical property database, and the logical structure design of this database was carried out.
