Query Processing Part III & IV: Convert Parse Tree into initial L.Q.P & Logical Optimization

CS525: Advanced Database Organizations.
Convert Parse Tree into initial L.Q.P:
- Convert the parse query tree to an initial query plan, which is usually an
algebraic representation of the query (relational algebra expression)

Logical Optimization:
- Cover ways of transformations to improve the query plan
Algebraic laws for improving query plans
