Onto-Translate relational database schema. This schema contains an entity for each of the source databases used by OT. The shapes represent the type of the given biological entity. A relationship between two databases is represented by a line connecting the two entities. The type of relationship between two entities is indicated by labels on the corresponding line. For instance, the relationship between Entrez Gene and Gene Ontology is many-to-many. In other words, a gene may be annotated using zero or more GO terms and a GO term may be used to annotate zero or more genes.
