Development of an animal genome database and its search system

An animal genome database has been developed on a Unix workstation and maintained by a relational database management system. This database has focused on the comparative gene mapping between species to assist the mapping of the genes related to phenotypic traits in livestock. The linkage maps, cytogenetic maps, polymerase chain reaction primers of pig, cattle, mouse and human, and their references have been included in the database, and the correspondence among species have been stipulated in the database. In order to search the database effectively, the World Wide Web server (http://ws4.niai.affrc.go.jp/) and the electronic mail server system (e-mail: jgbase-mail@ niai.affrc.go.jp) have been developed on different Unix workstations. These servers are connected to the Internet.
