摘要：This paper is based on relatively newer approach for query optimization in object databases, which usesquery decomposition and cached query results to improve execution a query. Issues that are focused here isfast retrieval and high reuse of cached queries, Decompose Query into Sub query, Decomposition ofcomplex queries into smaller for fast retrieval of result.Here we try to address another open area of query caching like handling wider queries. By using someparts of cached results helpful for answering other queries (wider Queries) and combining many cachedqueries while producing the result.Multiple experiments were performed to prove the productivity of this newer way of optimizing a query.The limitation of this technique is that it’s useful especially in scenarios where data manipulation rate isvery low as compared to data retrieval rate.
