AuthorRobert L. Bogue
Title

How a relational database solves and optimizes your query

AnnotationSome people view a relational database as a mystical oracle that answers questions posed to it by the programmer. However, there are a set of rules that a relational database uses to solve your query.

This article will walk you through a high-level overview of how a query analyzer tries to solve your query.
