大型数据库应用系统的优化技术

Optimization of Large Database Applications Systems

目的论述大型数据库应用系统的优化技术．方法先提出优化的必要性，然后分析优化的目的、方针、策略以及优化层面，最后给出了几种可以采用的优化技术，并分析了它们对数据库系统的特性和指标可能会造成的影响．结果给出使用Ｄｅｌｐｈｉ３开发应用的一些优化方法．结论使用者不但要充分掌握优化技术，还要熟悉应用领域的知识、数据库服务器和网络环境．评价优化技术，应以实际应用的效果为依据．

Aim To discuss the optimization of large database applications systems Methods Brings up the requrements of optimization,analyzes the purpose,guideline,strategy and layers of optimization Gives some technology in optimization together with their effects on characteristics and criteria of databases ystems Results Gives some specific methods of implementation using Delphi3 to develop Client/Server applications Conclusion Methods of optimization can be very complex and numerous,it requires the user not only to understand the technology,but also to be familiar with the application fields,DBMS and the network environment Evaluation of an optimization must be based upon the effect of actual applications
