Embedded Firebird database overview

Here are some great features of the Firebird embedded database version.

Identifying the Run-Time and the Design Mode

Sun, 11 Jan 2009 01:35:34 GMT

Some logic (like connecting to a database) is not meant to be called when the application is in design mode.

Handling a database connection is a run-time job only! This situation may be avoided if the run-time specific code is properly handled.
