The IBDsite data schema. Conceptual schema of the information content maintained in IBDsite. Data about H. sapiens genes that correlate to IBD are structured according to a gene-centric view. Annotation tables are related to the main one according to the gene identifiers, also used for structuring the ontology support and the systems biology layer. For commensal bacteria knowledge, the main table maintains data from literature, associating specific bacteria with the pathology and alteration mechanisms.
