System Requirements Analysis for the Chemical Structure and Nomenclature System (CSNS)

摘要

The Chemical Substances Information Network (CSIN) is a network of computer processors of chemical information, with two processors serving as central directories of the network: (1) a directory of data bases and the types of information contained in them and (2) a directory of chemical substances contained in or referenced by any of the network's data bases. A substance would be uniquely identified by its CAS Registry Number for systematic cross referencing. This substance identification processor is called the Chemical Structure and Nomenclature System (CSNS). It will enable CSIN users to determine whether a particular substance exists and which substances in some generic class exist in the network. The report presents a plan for CSNS development: functional and operational requirements, design alternatives, existing systems, and a developmental approach.
