IBExpert:If you are interested in using Firebid database on Windows OS, one of the most recomended tools you can count on is IBExpert which offers you a variety of functions and interfaced for a easy administration and use of Firebird capabilities.
Some of the features are:
-Code completion
-Stored Procedure and Trigger Debugger including Trace Into, conditional breakpoints, and much more
-Visual Query Builder
-Autoinc Assistant for Trigger, Generator and Stored Procedure creation, etc.
Educational Version is full version limited to 50MB database and there is a Personal Version with some limited functionalities
I strongly recommend this tool, as I’m using it since early 2004.
