摘要
提出一种优良的基于SAAS模式的共享数据模型的多租户数据扩展方法。首先简单地介绍了SAAS模式及其数据模型,并详细阐述了目前基于SAAS模式的共享数据模型的多租户数据扩展技术的优缺点;最后,提出一种以XML为基础的共享数据模型的多租户数据扩展方法,并且详细介绍了在此方法下灵活的数据操作及其性能分析,并将其与目前常用的基于SAAS模式的共享数据模型的多租户数据扩展方法进行对比分析,可得在SAAS系统中应用基于XML的共享数据模型的多租户数据扩展方法是性能优良的。
It aims to propose a preferred multi-tenant data extension method based on shared data model of SAAS pattern.It first explains simply the SAAS pattern and data model of SAAS pattern,describes in detail advantages and disadvantages of multi-tenant data extension technology based on the current shared data model of SAAS pattern;Finally propose a XML-based multi-tenant data extension method based on shared data model of SAAS pattern,and describe in detail flexible data operation and performance evaluation under this method.It＇s preferred to apply XML-based multi-tenant data extension method based on shared data model,compared with normal multi-tenant data extension method based on shared data model of SAAS pattern at present.
