This document describes Keires_DB, an ORM library for PHP. It provides an object-relational mapping for PostgreSQL databases. Key features include using PDO for database access, late static binding support for PHP 5.3+, and defining database schemas and models through class declarations. Examples demonstrate basic CRUD operations and querying data through both object and raw SQL methods.
