Web Performance is not only about understanding what makes a site fast. Performance is a feature and needs to be prioritized as such. Performance is a topic that has interested me for a long time. Moving over to web, the performance problems are different. This is not a post explaining why web performance is important.

Unnesting/substitution of table expressions is a process of taking a query that involves nesting of table expressions, and as if substituting it with a query where the nested logic is eliminated. What actually happens is that the query parsing process produces an initial tree of logical operators closely reflecting the original query.
