AeroSQL is a Web-based tool for managing MySQL servers. It allows you to control multiple servers, updat the result of a SELECT if it is performed on a single table and the result contains a unique index and view all SQL commands issued by the server side script. It correctly handles NULL values, allows users to select which columns to display while editing a database table, and only fetches visible columns to minimize network traffic. It feature an easy to use Web interface based on the ExtJS framework.
mysql-diff is a commandline database structure comparator. It compares the structure of two databases. It currently works with MySQL. A database can be specified as an SQL script or as an URL to a running database. So the tool can compare two scripts, two live databases, or a database and a script. The tool outputs SQL DDL script that can be used to convert one schema to another.
mysqlviz renders a graphical representation of a MySQL database from a mysqldump file. Features include speed, the ability to infer foreign key relationships if you do not have them defined, and handling of partial dumps (i.e. foreign keys to tables that are not defined within the dump).
Pdbsql provides three samba passdb backend modules: pdb_mysql, pdb_pgsql, and pdb_multi. pdb_mysql is a MySQL passdb backend. pdb_pgsql is a PostgreSQL passdb backend. pdb_multi is a backend which loads multiple passdb backends. These are provided because support for MySQL and PostGreSQL passdb backends has been removed from the Samba source tree, due to lack of an active maintainer.
