%X The semi-join relational operation is augmented and a new method for solving cyclic queries in distributed databases is described in the paper. This new method can fully reduce all the relations in a cyclic query. 5n-4 times of data transmission is required to carry out this new method, where n stands for the number of nodes in the query graph.
