= MySQL =

  URL:: http://www.mysql.com/
  license:: GPLv2
  platforms:: Unix, win32, win64, MacOS X, i5/OS

== Pros ==

 * Easy to install and administer
 * Support for many SQL Features (v5.0 and up):
  * Good compliance with SQL standards
  * Foreign Keys (using InnoDB)
  * Stored Routines
  * Views
  * Triggers
 * Subqueries (as of v4.1)
 * Partitioning (as of v5.1)
 * ACID compliant (InnoDB and NDB storage engines)
 * Character set support
 * Built-in Replication
 * Many administration tools from third parties
 * Widely deployed
 * Regarded as being fast
 * Modular storage engines and interesting clustering features

== Cons ==

 * Early versions (v4.1 and earlier) have the reputation for only basic SQL support (entry-level SQL 92) and deviations from the standards. Many interesting features (views, triggers,..) are included in the latest version (5 and above), but are missing in prior versions. Check [[http://dev.mysql.com/doc/refman/5.1/en/server-sql-mode.html|SQL Modes]] for making MySQL more strict.
 * Some [[http://sql-info.de/mysql/gotchas.html|gotchas]] for MySQL v4.1 and earlier.

mxODBC Connect is a commercial client-server product that allows connecting Python to ODBC compatible databases running on remote servers without requiring an ODBC driver on the client side. The product uses mxODBC on the server side and provides a highly portable Python library for the client side. As such it supports all database backend that mxODBC supports, but allows connecting to these from many different Python-supported platforms.

mxODBC Connect supports asynchronous query execution via the popular [[http://www.gevent.org/|gevent package]], provides secure certificate based authentication, SSL encrypted database connections, comes with full support for stored procedures, multiple result sets, Unicode, a common interface on all platforms and implements [[http://www.egenix.com/products/python/mxODBCConnect/#Features|many other useful features]].

mxODBC Connect Server is compatible with the MySQL ODBC drivers.
