 * This library includes all the required functions used to handle the DB
 * structure (DDL) independently of the underlying RDBMS in use. All the functions
 * rely on the XMLDBDriver classes to be able to generate the correct SQL
 * syntax needed by each DB.
 *
 * To define any structure to be created we'll use the schema defined
 * by the XMLDB classes, for tables, fields, indexes, keys and other
 * statements instead of direct handling of SQL sentences.
 *
 * This library should be used, exclusively, by the installation and
 * upgrade process of Moodle.
