* MySQL specificities:

* the SQL standard.
* - 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.
