%X Data management of the large-scale symmetrical matrices,as a bottleneck of the data management under International Terrestrial Reference Frame (ITRF) is discussed.We set up a symmetry-relationship model to convert the half-structural matrices into full-structural relationship tables with fixed fields,then set up the symmetry-relationship database in accordence with extended relationship principles. This symmetry-relationship model can be used to improve the efficiency of the information management under ITRF.
