table_name,table_description
molecule,"Stores one record per molecule with a unique text ID, an assessment outcome code, a coded risk classification, and the date it was entered into the catalog. Each molecule undergoes evaluation and receives classification codes based on the assessment protocol."
bond,"Stores one record per chemical bond within a molecule. Each bond_id encodes the molecule and atom pair (TRxxx_A1_A2), linking to the molecule via molecule_id. The bond_type column classifies each bond's order. This table can be used for connectivity analysis by parsing the atom references embedded in bond_id."
connected,"Stores pairwise atom connectivity records, mapping each bond to its two participating atoms through separate atom_id and atom_id2 columns with a corresponding bond_id reference. Each bond appears as two reciprocal rows (one per direction)."
atom_bonds,Normalized molecular connectivity index that stores each bond relationship exactly once in canonical form (source_atom < target_atom). Provides deduplicated connectivity references for standardized bond enumeration and molecular graph analysis.
atom,"This table stores one record per atom, with a unique atom_id, the molecule_id of its parent molecule, and the atom's chemical element."
