1.5.5 Feature Differences Between MaxDB and MySQL
-------------------------------------------------
MaxDB is MySQL AB's SAP-certified database. The MaxDB database server
complements the MySQL AB product portfolio. Some MaxDB features are not
available on the MySQL database management server and vice versa.
The following list summarizes the main differences between MaxDB and
MySQL; it is not complete.
* MaxDB runs as a client/server system. MySQL can run as a
client/server system or as an embedded system.
* MaxDB might not run on all platforms supported by MySQL.
* MaxDB uses a proprietary network protocol for client/server
communication. MySQL uses either TCP/IP (with or without SSL
encryption), sockets (under Unix-like systems), or named pipes or
shared memory (under Windows NT-family systems).
* MaxDB supports stored procedures and functions. MySQL 5.0 and up
also supports stored procedures and function and functions. MaxDB
supports programming of triggers through an SQL extension. MySQL
5.0 supports triggers. MaxDB contains a debugger for stored
procedure languages, can cascade nested triggers, and supports
multiple triggers per action and row.
* MaxDB is distributed with user interfaces that are text-based,
graphical, or Web-based. MySQL is distributed with text-based user
interfaces only; graphical user interfaces (MySQL Query Browser,
MySQL Administrator) are shipped separately from the main
distributions. Web-based user interfaces for MySQL are offered by
third parties.
* MaxDB supports a number of programming interfaces that also are
supported by MySQL. For developing with MaxDB, the MaxDB ODBC
Driver, SQL Database Connectivity (SQLDBC), JDBC Driver, Perl and
Python modules and a MaxDB PHP extension, which provides access to
MySQL MaxDB databases using PHP, are available. Third Party
Programming Interfaces: Support for OLE DB, ADO, DAO, RDO and .NET
through ODBC. MaxDB supports embedded SQL with C/C++.
* MaxDB includes administrative features that MySQL does not have:
job scheduling by time, event, and alert, and sending messages to
a database administrator on alert thresholds. (MySQL has
scheduling support starting with version 5.1.6.)
