The Toad toolset runs against Oracle, SQL Server, IBM DB2 (LUW & z/OS), SAP and MySQL.

A practicing Oracle DBA, Jim McDaniel, designed Toad for his own use in the mid-1990s.

[1] He called it Tool for Oracle Application Developers, shortened to "TOAD".

McDaniel initially distributed the tool as shareware and later online as freeware.
