A joint arithmetic of multi-table based on a general relative database is put forward. The question of minimum spanning tree with equal weight on the edge is described. Using table name of database as vertexes, using unit Euclidean distance as weight on the edge and using primary key among tables as a joint condition, the minimum spanning tree among tables with design of corresponding C++program is gotten. The result show the relation among tables is obtained high-efficiently
