Trương Ngọc Châu, Đoàn Văn Ban

Abstract


In large databases in general and Object-Oriented Database in particular, the queries on databases often contain conditional expression finding including complicated conjunctions and disjunctions. This article studies and proposes ways to optimize complicated finding conditional expression, which have container path expressions using nested indexes.
