A procedure to build a database by Hood's software is introduced from an example of global Cretaceous Oceanic Red Beds. It is suggested that the procession of the database is going to be executed as: new files of stratigraphic sections→taxonomic dictionary files→catalog files→running the software GraphCor-results of database and graphs of correlation + sedimentary data + geochemistry data→composite database. Some discussions on the choice of standard correlation section, first and last occurrence of a taxonomic, update and linkage of data are made.

以全球白垩纪大洋红层为例，介绍了运用GraphCor软件进行地层对比数据库建立的程序：建立剖面文件→建立化石分类单元库文件→建立目录文件→运行GraphCor软件，获得数据库和图示对比结果＋沉积、地球化学信息＋地层柱状图→综合数据库；讨论了有关对比标准参考剖面的选取、分类单元的始现和末现层位、数据库的更新及衔接等问题。
