摘　　要：为了解决以"大集中"方式设计的企业管理系统的查询性能下降的问题,提出了完善的查询性能优化模型。该模型是在对通用查询性能优化模型进行分析与的对SAP系统查询性能优化方法的研究基础之上,加入了业务规则优化层,从而使软件技术与业务规则优化相结合而形成的。通过完善的查询性能优化模型在电力系统发展建设的应用实例,验证了所提模型在提高以"大集中"方式设计的企业管理系统的查询性能方面的有效性。In order to solve query performance degradation problems of the enterprise management system designed by ＂big focus＂ approach, and propose a sound query performance optimization model. The model is a general-purpose query performance analysis and optimization model against the SAP system, query performance optimization method based on the study, joined the business rules, optimization layer, so that software technology and business rules, optimization of a combination formed. By improving the query performance optimization model of development and construction in the power system application example to verify the proposed model in improving the ＂big focus＂ approach enterprise management system designed to query performance effectiveness.

关 键 词：查询性能优化模型 缓存技术 分页技术 业务规则 业务逻辑
