A poor logical database design can hinder the performance of the whole system 邏輯數據庫設計不好,會影響整個系統的性能。
Sometimes , the logical database design is already fixed and total redesign is not realistic 有時,邏輯數據庫設計已經固定,全部進行重新設計是不現實的。
A good logical database design can lay the foundation for optimal database and application performance 設計好邏輯數據庫,可以為優化數據庫和應用程序性能打下基礎。
Normalizing a logical database design involves using formal methods to separate the data into multiple , related tables 規范化邏輯數據庫設計包括使用正規的方法來將數據分為多個相關的表。
After normalizing your data model as far as you have intended during the logical database design process , then include some degree of de - normalization as one of the potential performance tuning options 在邏輯數據庫設計過程中,您可以毫無保留地規范化數據模型,然后再加入一定程度的反規范化,作為潛在的性能調優的一種選擇。
The thesis also analyzes how to optimize the performance of the whole distance education supporting platform based on sql server7 . 0 database , and emphasizes on the four aspects of logical database design , index usability , query structure and procedure objects . it also discusses the extension of system functions from the point of view of database design in order to realize the distance education quality appraisal and tracking in the future 對基于sqlserver7 . 0數據庫的整個遠程教育支撐平臺系統的性能優化進行分析,著重從邏輯數據庫設計、索引的可用性、查詢結構和過程對象的使用四個方面進行論述,并從數據庫設計角度討論了對系統進行功能擴展,以實現未來對遠程教育質量評價和教學質量跟蹤。
