A major obstacle in ensuring ubiquitous information is the utilization of heterogeneous systems in eHealth. The objective in this paper is to illustrate how an architecture for distributed eHealth databases can be designed without lacking the characteristic features of traditional sustainable databases. The approach is firstly to explain traditional architecture in central and homogeneous distributed database computing, followed by a possible approach to use an architectural framework to obtain sustainability across disparate systems i.e. heterogeneous databases, concluded with a discussion. It is seen that through a method of using relaxed ACID properties on a service-oriented architecture it is possible to achieve data consistency which is essential when ensuring sustainable interoperability.
确保信息无处不在的一个主要障碍是电子健康领域中异构系统的使用。本文的目的是说明如何设计分布式电子健康数据库的架构，同时又不缺乏传统可持续数据库的特征。方法是首先解释集中式和同构分布式数据库计算中的传统架构，接着探讨一种可能的方法，即使用架构框架来实现不同系统（即异构数据库）间的可持续性，最后进行讨论。可以看出，通过在面向服务的架构上使用宽松的ACID属性的方法，能够实现数据一致性，这在确保可持续互操作性时至关重要。
