· MaxDB is a system that operates in client/server mode. MySQL can run as a client/server system or as an embedded system.

· MaxDB may not run on all platforms supported by MySQL.

· MaxDB adopts the VPC protocol for client/server communication. MySQL uses TCP/IP (with or without SSL encryption), socket protocol (in Unix-like systems), or named pipe (in Windows NT series ).

· MaxDB supports storage programs. MySQL 5.0 implements storage programs. MaxDB also supports triggering program programming through SQL extension, which is planned to be implemented in MySQL 5.1. MaxDB contains debugging programs for the storage program language. it can concatenate multiple nested triggers, and each action and row supports multiple triggers.

MySQL is released only on the text-based user interface: the graphical user interface (MySQL control center, MySQL manager) is provided separately with the main release version. Web-based user interfaces for MySQL are provided by a third party.

· MaxDB supports a variety of programming interfaces also supported by MySQL. To use MaxDB for development, we also provide the MaxDB ODBC driver, sqldatabase connection (SQLDBC), JDBC driver, Perl and Python modules, and MaxDB PHP extensions (using PHP to access the MySQL MaxDB database ). Third-party programming interfaces: supports ole db, ADO, DAO, RDO, and. NET and ODBC. MaxDB supports embedded SQL and C/C ++.
