Schema design for a molecular biology laboratory informationmanagement system

摘要

The development of the conceptual scheme for the databasensupporting the laboratory activities for the mapping phase of the HumannGenome Project at Lawrence Berkeley Laboratory is discussed. Thisnentailed recording the instances of molecular biology experiments, thendata generated from the experiments, and the inventories of biologicalnstocks and chemical compounds. The authors discuss the nature of thenapplication, the major modeling problems they confront, and thenmethodology they have adopted to address some of these problems. Thenmethodology they adopted combines elements of an extendednentity-relation model with those of a data-flow model
