The ArrayGene database contains the genexref table which provides cross references between sequence identifiers and Entrez Genes and the arrays_table table storing all the information about microarray annotations.
Although database is applied loosely to any collection of information in computer files, a database in the strict sense provides cross-referencing capabilities.
Beyond above characteristics, the eFG database provides cross-references to other databases.
The humdisease.txt file lists, for each disease, its name, acronym, synonyms, phenotypic description, and MeSH terms, and provides cross-references to the OMIM database.
The interrelated dataset of soybean genes, in combination with related Arabidopsis and rice TF annotations, were implemented into the SoybeanTFDB to provide cross references with other plant TFDBs.
One effort to help students navigate the Talmud, Mesoras HaShas, provided cross-references alongside the Aramaic text toward similar ideas elsewhere in the Talmud.
There are also publications that provide cross-references for similar steel grades among the various standards and trademarks issued in different countries.
Databases increasingly provide cross-references between chemical records, patent documents, PubMed abstracts and a small proportion of full-text papers.
Moreover, the tool editor provided cross-reference, error verification, and auto-complete new features to facilitate the task of architectural specification.
Since not all chemical databases provide cross-references to all other databases, it is usually not enough to annotate metabolites with only one type of identifier.
Many of these PubChem records (substances, compounds, and assays) have depositor-provided cross-references to scientific articles in PubMed (https://www.pubmed.gov) [8 11], a biomedical literature search system developed and maintained by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), an institute within NIH.
