After downloading it from the Internet, the beta version was installed in a few minutes. There was no problem installing or running on Windows ME, even though the Oracle software is not supported on that Windows release. The only difficulty I did encounter was in installing an older production version over the trial version. However, with a de-install and few reboots, the problems were resolved. What it does TOAD provides the development environment that Oracle doesn't.
Toad provides a number of windows in which to work.
Schema Browser - where easy access is provided to the data dictionary. A neat feature in this window is that the data within the tables can also be displayed, edited and committed back to the database. Procedure Editor - fully integrated with the oracle debugger and profiler, this window provides a great environment for editing stored code. It goes beyond a simple editor, though, by also providing advanced features such as source control and templates for new objects. SQL Modeler - now there is no need to write complex SQL statements by hand.
