Construction of the biostratigraphic database and its significance

Abstract：Construction of a biostratigraphic database is a long-term basic disciplinary project of far-reaching significance. The construction work includes standardizing the database construction flow process strictly, establishing the biostratigraphic database data-relationship and framework, developing operating system softwares, setting several inquiry functions, giving prominence to practical applicability and sharing achievements. The stratobiomarks database of China (Web edition) has been constructed recently based on collection, collation and study of biostratigraphic data. The computer technique is used to systematize, standardize and digitize the data, improve the Chronostratigraphic Table of China, unify the standards of stratigraphic division and correlation and solve some scientific problems. The construction of the biostratigraphic database involves all geologic ages and countrywide biostratigraphic databases, and it can strengthen the techno-support function of the basic discipline and promote the development of biostratigraphy.
