分布式数据库中语义完整性检查的实现——C-POREL 系统完整性检查模块设计

IMPLEMENTATION OF SEMANTIC INTEGRITY TEST IN DDE---THE DESIGN OF INTEGRITY TEST MODULE FOR C-POREL SYSTEM

本文介绍了分布式数据库管理系统DDBMS C-POREL中语义完整性检查的实现技术以及完整性检查模块的设计。提出了完整性约束的四种类型和完整性检查的先决条件,阐述了优化完整性约束和优化完整性检查范围的算法,讨论了断言实施代码分布的控制策略。

The paper introduces the implementation techniques and design of semantic integrity test for distributed databas DDBMS C-POREL, puts forward four kinds of integrity constrains and the precondition of integrity test, illuminates algorithms used in optimizing integrity constrains, and test and discusses the control strategy about the distribution of assertion execution code.
