This document provides an overview of the new INFORMATION_SCHEMA feature in MySQL 5.0, which allows accessing database metadata through standard SQL queries rather than non-standard SHOW commands. It describes the various tables in INFORMATION_SCHEMA, including CHARACTER_SETS, COLLATIONS, COLUMNS, and others, explaining what information they provide and how it relates to the output of equivalent SHOW commands. The document also provides examples of queries against these tables.
