Query Processing with Relational Operations

This lecture covers the fundamentals of query processing with relational operations, including query optimization, physical query plans, query execution models like the Volcano model, and examples of physical query plans such as nested loop and pipelined execution. It also delves into topics like query optimization for selections, indexing, and access methods, as well as the implementation of relational operators like selection, projection, join, set-difference, union, aggregation, and group by. The lecture concludes with a discussion on different join algorithms, such as nested loops, block nested loops, and hash joins, and their associated costs.
