摘要：The role of materialized views is becoming vital in today’s distributed Data warehouses. Materialization iswhere parts of the data cube are pre-computed. Some of the real time distributed architectures aremaintaining materialization transparencies in the sense the users are not known with the materialization ata node. Usually what all followed by them is a cache maintenance mechanism where the query results arecached. When a query requesting materialization arrives at a distributed node it checks in its cache and ifthe materialization is available answers the query. What if materialization is not available- the nodecommunicates the query in the network until a node answering the requested materialization is available.This type of network communication increases the number of query forwarding’s between nodes. The aimof this paper is to reduce the multiple redirects. In this paper we propose a new CB-pattern tree indexing toidentify the exact distributed node where the needed materialization is available.
