A number of algorithm have been proposed for self-maintenance of views where they keep some additional information in data warehouse in the form of auxiliary views. The purpose of this paper is to research consistency problem when self-maintenance of views is implemented. The proposed "conveyor algorithm" will resolved a complete consistency of materialized view using self-maintenance with considering network delay. The rationale for conveyor algorithm and performance characteristics are described in detail.
