The database applications based on distributed and heterogeneous problems are increasing rapidly, and the architecture of inter-access of heterogeneous database needs to be perfected and updated.

随着数据库实践中基于分布、异构问题的进一步增多，异构数据库互访的实现需要进一步完善和更新。

With PCI address mapping mechanism, this research realized the inter-access between host and backup based on CPCI bus and the coherence between host and backup is thus realized.

借助pci地址映射机制，本课题基于CPCI总线实现了主备间的内存互访，并依此实现了主备间的一致性。
