SRS Universe example view of database linkage. The scientific database network consists of well-known interlinked biological databases. Microarray datasets are coupled to this network through a multi-linked Affymetrix coupling file, the single UniGene-linked NKB/NKI-coupling file, or directly to UniGene using GenBank accession numbers. For clarity, not all databases and links mentioned are represented in the scheme. Public SRS servers and indexed scientific databases can be viewed at .
