// This library includes all the required functions used to handle the DB
// structure 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.
