What is Cost-Based Query Optimization Guide about?

The document discusses query optimization in a database management system. It describes the key steps in cost-based query optimization as parsing, transformation, implementation, and plan selection based on cost estimates. The goal is to process queries in the most efficient way to minimize costs like disk I/O time. Transformations are applied to algebraic expressions representing the query to find lower-cost execution plans.
