Property Graph Techniques in Relational Databases
AI总结：
本文研究将SQL外键建模为引用键，实现关系型数据库与属性图数据库的统一，支持PGDMS的图操作及多类型图模型构建。
AI中文摘要：
当前数据库管理系统的标准化工作进展包括结构化查询语言（SQL）后续版本的开发，以及带标签属性图的相关标准制定。本短文探索了基于记录的关系型数据库与属性图数据库的统一实现机制：其贡献在于将SQL外键建模为引用键，可支持属性图数据库管理系统（PGDMS）的图插入与高级模式匹配机制，还能在单个关系型数据库上构建多类型图模型。
英文摘要：
Current developments in standardization activities for database management systems include the development of the next versions of the Structured Query Language (SQL), and related standards for labelled property graphs. This short paper explores mechanisms for unified implementation of record-based relational and property graph databases: its contribution is that modeling SQL foreign keys as reference keys facilitates the graph insert and advanced pattern matching mechanisms of Property Graph Database Management Systems (PGDMS) and allows the construction of multiple type graph models on a single relational database.
