%X Database availability was one of the basic indexes of database system performance. It was usually analyzed with a view to the whole characteristic.The limitation of this method was pointed out and a new measure was presented and applied to the distributed and parallel database system(DPDBS). Based on the logical grouping of server nodes,discussed the availability of DPDBS from data resources angle. Then, analyzed and compared the data resource availability of several familiar database systems.
