Relational database schema representing schematically the data warehouse built by TAGOPSIN. Primary key (PK) attributes (allowing unique identification) are in bold and underlined. An arbitrary PK was chosen where a satisfactory biological attribute could not symbolize it (e.g. OID, CDS ID, NTS ID). Foreign key attributes are indicated by (FK). Arrows indicate how one relation is linked to another. Start, Stop: start and end positions on the corresponding sequence; SP Start, SP Stop: start and end positions on the Swiss-Prot sequence; PDB Start, PDB Stop: start and end positions on the PDB structure
