1.0 Executive Summary SQLite4 is a compact, self-contained, zero-adminstration, ACID database engine in a library, just like SQLite3, but with an improved interface and file format. The run-time environment is encapsulated in an object. A greatly simplified Key/Value storage engine is used: A single large key space - not separate key spaces for each table and index as in SQLite3. Keys sort in lexi

1. Introduction This document provides an overview of how the query planner and optimizer for SQLite works. Given a single SQL statement, there might be dozens, hundreds, or even thousands of ways to implement that statement, depending on the complexity of the statement itself and of the underlying database schema. The task of the query planner is to select the algorithm that minimizes disk I/O an
