+ * - all integer types can have an optional (non-standard) attribute
+ * UNSIGNED (http://dev.mysql.com/doc/mysql/en/numeric-types.html)
+ *
+ * SQLite3 specificities:
+ * - any column (but only one for each table) with the exact type of
+ * 'INTEGER PRIMARY KEY' is taken as auto-increment.
+ * - the supported data types are: NULL, INTEGER, REAL, TEXT and BLOB
+ * (http://www.sqlite.org/datatype3.html)
+ * - the size of TEXT cannot be set, it is just ignored by the engine.
+ * - IMPORTANT: foreign key constraints are not yet supported
+ * (http://www.sqlite.org/omitted.html). Included in case of future
+ * support.
+ *
+ * Notes:
+ * - the SQL queries will take advantage of the most appropriate data
+ * types supported by a particular database engine in order to
+ * optimize the server database size.
