一句话:提出通过等价查询重写测试图数据库系统,以暴露逻辑错误、性能缺陷和异常问题。
图数据库管理系统(GDBMS)以图模型存储数据并通过图遍历执行查询,已广泛用于推荐系统、知识图谱和社交网络。与关系数据库类似,GDBMS 也可能存在缺陷。这些缺陷通常表现为三类:逻辑错误导致结果不正确(如遗漏应包含的节点)、性能错误(如冗余图扫描造成执行时间过长)以及异常问题(如意外抛出或缺失异常)。论文标题表明其方法为等价查询重写,即通过构造语义等价但形式不同的查询来测试系统行为,从而暴露上述问题。摘要未提供具体实验评估结果,但明确了 GDBMS 测试应关注结果正确性、性能和异常行为。
Graph Database Management Systems (GDBMS), which utilize graph models for data storage and execute queries via graph traversals, have seen ubiquitous usage in real-world scenarios such as recommendation systems, knowledge graphs, and social networks. Much like Relational Database Management Systems (RDBMS), GDBMS are not immune to bugs. These bugs typically manifest as logic errors that yield incorrect results (e.g., omitting a node that should be included), performance bugs (e.g., long execution time caused by redundant graph scanning), and exception issues (e.g., unexpected or missing exceptions).
