我们考虑在与词典的复杂值上定义的路径连接性查询和约束（依赖关系）类别。该类包括关系连词的查询和嵌入式依赖关系，以及许多有趣的复杂价值和OODB查询和完整性约束的示例。我们表明，关于遏制，依赖性含义和追逐的一些重要经典结果扩展并推广到该类别。
We consider the class of path-conjunctive queries and constraints (dependencies) defined over complex values with dictionaries. This class includes the relational conjunctive queries and embedded dependencies, as well as many interesting examples of complex value and OODB queries and integrity constraints. We show that some important classical results on containment, dependency implication, and chasing extend and generalize to this class.
