摘要： 由于关系型数据库和图数据库存储模式的天然差别,将关系型数据库中的数据转存到图数据库的过程中,需解决对于关系的定义、节点唯一性以及保留原数据库约束信息的主要问题。针对上述问题,提出了一种关系型数据库向图数据库转换的方法。首先通过自定义或使用已有主键,并结合数据库表名的唯一性,解决了节点唯一性的问题;通过不同的配置方案,最大化保留了原关系型数据库的约束信息;然后提出了基于配置与中间表的边定义方法(Edge Definition Method based on Configuration and Intermediate Table,EDCIT),针对多种类型的数据库提供不同关系的映射方案,解决了转换过程中对于关系的定义。最终,通过对多个数据集进行实验,并使用Gremlin语句对转换后的数据进行测试,验证了转换后的数据具有完整性和可靠性。
