/**
 * Object representation of a database schema.
 *
 * Different vendors have very inconsistent naming with regard to the concept
 * of a "schema". Doctrine understands a schema as the entity that conceptually
 * wraps a set of database objects such as tables, sequences, indexes and
 * foreign keys that belong to each other into a namespace. A Doctrine Schema
 * has nothing to do with the "SCHEMA" defined as in PostgreSQL, it is more
 * related to the concept of "DATABASE" that exists in MySQL and PostgreSQL.
 *
 * Every asset in the doctrine schema has a name. A name consists of either a
 * namespace.local name pair or just a local unqualified name.
 *
 * The abstraction layer that covers a PostgreSQL schema is the namespace of an
 * database object (asset). A schema can have a name, which will be used as
 * default namespace for the unqualified database objects that are created in
 * the schema.
 *
 * In the case of MySQL where cross-database queries are allowed this leads to
 * databases being "misinterpreted" as namespaces. This is intentional, however
 * the CREATE/DROP SQL visitors will just filter this queries and do not
 * execute them. Only the queries for the currently connected database are
 * executed.
