摘　　要：异构数据库之间不能安全流畅地交换数据是大企业实现信息集成的主要瓶颈之一。针对以往异构数据库之间数据交换实现困难、安全性差的问题,提出了一种安全异构数据交换技术。利用XML模板映射和数字签名技术,并在内外网数据库之间采用网络隔离技术,实现了内外网异构数据库之间的透明互操作,充分保证了数据的安全性和完整性。方案在实际工程案例中应用,取得了良好的效果。One of the primary bottlenecks preventing large enterprises from integrating information is that data cannot be exchanged smoothly among heterogeneous databases. A technique of security heterogeneous data exchange is proposed to deal with troubles in terms of data exchange between heterogeneous databases and poor security. XML template mapping and digital signature technology, together with network gap technology between internal and external network databases, is used to make operation between external and internal network heterogeneous database transparent, fully guaranteeing data security and integrity. Such solution to a practical project has been proved sound.
