Section 3: Analyzing Logical vs. Physical Reads Balancing logical and physical reads is vital for optimal database performance. While logical reads are generally preferred for their speed, physical reads are sometimes inevitable. The key is to optimize queries and ...
A technique for serializing both logical and physical meta-model information in a single file is disclosed. In an embodiment, the logical meta-model information is serialized in an Extensible Marking Language (XML) schema compliant format, and the physical meta-model information is inserted into the...

The query optimizer uses operators to build a query plan ...
A knowledge-based system for physical database design has been developed at the Institute for Computer Sciences and Technology. This system processes large multi-entity logical data structures with complex workload requirements and identifies near-optimal physical designs. It employs heuristics developed ...
conceptual design to a logical design. Mapping from an ER diagram to a relational database will convert an entity to a relation with a primary key and its associated attributes. Conceptual design and logical database design are iterative processes. They are critical to the overall success of ...
