DIRM:A Model for Data Query Based on Dynamic Information Route Approach

A new model of DIRM (Dynamic Information Route Model) was proposed.The concept of information dynamic route based on information organization model was put forward,and the structural or the semi-structural data query was completed using the information route from host.Three algorithms: Information Query Algorithm, DIRA( Dynamic Information Route Algorithm), IRH Route Exchange Algorithm of the Boundary Area were proposed.The lemma of query equivalent and lemma of limited steps was proved and the complexity of information query algorithm in different conditions was discussed.
