Synonym database schema. This figure represents the database schema for the synonym databases. There are three tables, Info, DataNode and Link. Info provides meta-data on the database. DataNode provides per-gene information, and Link provides a many-to-many relation between entries in the DataNode table that is used to store cross-references. The id column contains accession numbers from online biological databases. Systemcode is a short code (usually one or two letters) that represents the biological database that the id belongs to. A back-page is a short summary of the entity with HTML mark-up, containing at least a one-line description.
