可以通过定义物化查询表(Materialized QueryTables, MQT)——以前称为自动总结表(Automatic Summary Tables,AST)——来在本地缓存引用关系和非关系昵称的查询的结果。
Materialized Query Tables (MQTs), formerly known as Automatic Summary Tables (ASTs), can be defined to locally cache the result of queries that reference relational and non-relational nicknames.
研究和实现了图论中无向图的简单路径查找算法，对连锁表的编制规则进行了总结，实现了相应的联锁表自动生成算法。
Based on the research of the rules to compose the interlocking table and simple path search of graph, we design an algorithm to generate the interlocking table from signal arrangement.
