Optimization of Complex Nested Queries in Relational Databases
Due to the flexible structures of SQL, no general approach works efficiently for all kinds of queries. Some special kinds of queries can be further optimized for better performance. In this dissertation, we study two kinds of such queries: one is queries having non-aggregate subqueries and the other is queries having redundancy. To deal uniformly with non-aggregate subqueries in SQL, we propose the nested relational approach based on the nested relational model. To deal with redundancy in complex SQL queries, we propose the redundancy awareness method with
