摘要
A system to optimize layout of database objects in a relational database management system stored on a plurality of storage classes each characterized by a price and a storage capacity includes a time-based query optimizer and a layout recommender coupled to the time-based query optimizer to estimate a total cost of operation (TCO) for a query workload on each data layout. The layout recommender includes an auxiliary object selection comprising database objects that include auxiliary objects that are optional to place with auxiliary object candidates being given from an auxiliary object recommender component.
