One day I have followed a refer link to TurboBird page, in that link a Russian guy has talked about TurboBird, another one commented "writing admin tool for Firebird using IBX is a bad idea" and since then I was wondering is it bad idea to use Interbase library for FireBird, and is IBConnection and FireBird library depend on Interbase, and what is the best FireBird library that should be used with Lazarus applications?
