EMBL-search: a CD-ROM based database query system.

This paper describes a system of generally applicable index files provided on the EMBL sequence databases CD-ROM to facilitate the development of front-end software to the sequence databases available on this CD-ROM. The index files are used by a new versatile and user-friendly database retrieval program for the Apple Macintosh, EMBL-Search, which allows the easy construction of complex database queries. EMBL-Search utilizes cross-reference information contained in the databases to support navigation between different information resources. The ability to run EMBL-Search on a local computer network accessing a shared database CD-ROM makes its use particularly cost effective.
