Abstract

The paper introduces an improvement of an approach for tree representation in relational tables. Tree structures are widely used in the area of the computer systems. Often is needed to store trees in relational databases. But the relational model does not supports datatypes for such an objects. The conventional methods to store trees suffer from the limitations of the relational model. The present paper offers some modifications of an existing method - path enumeration model. A number of experiments were conducted and the results show improvement in manipulation time of the trees.
