Abstract
An access structure analysis method is interspersed with the query optimization process. The method can determine the ideal combination of access structures, including both materialized views and indexes, for a given database workload. The interspersed structure analysis method can include advanced transformations like view merging, star transformation, bitmap access plans, query rewrite using materialized views, for example. The method may be performed using the query optimizer's rules as heuristics to guide the index candidate generation process.
