Lineage tracing queries help to locate updated views quickly in data warehouse. Materialized views can improve the efficiency of the data lineage tracing and view maintenance. This paper, a method to select materialized views using Top-k query algorithm is presented. The selection is based on the query frequency, the view storage space and maintenance cost. Experimental results show that Top-k query algorithm has a better query performance than the Heuristic algorithm for lineage tracing query.
