This article was originally created for Databazovy Svet (in Czech) and covers a little bit more about this topic. This shortened version is focused only on solutions for Firebird, without any other stuff.
Sometimes I see question(s) in forums, groups, lists about ability to run program from trigger or better to say perform some action done by external program. Well you can create many of possible solutions, working best for your case. But I’ll cover two “special” features available in Firebird that can help you with this

Comparing the performance of several operations in FB2.1, OraXE and SQLServerXE using the vendor specific .NET data access drivers, I discovered Firebird was about 3 times faster than the others which were both nearly the same speed.
You may wonder, how the Entity Framework will map some basic functions (concatenation, average, etc.) from i.e. LINQ or from EntitySQL to functions supported by database and what functions will be “the selected”. Well the answer is easy.

I’m in the extremely lucky situation that I’ve just started a brand new project, in which I can choose technology. A part of the project is to replace an old Web Project written in Delphi 5 ! and a larger part is going to be new. The main bulk of the project is going to as a web application run on portable barcode readers in a production enviroment. Speed is important.
The 2nd part of the Interbase and Firebird Developer’s manual for ADO .Net has published. It describe code generators and Visual Studio 2005/2008 tools.
by jirkaWe’re moving, slowly, step-by-step. And new functionality is coming in view. Just two pictures showing a piece of functionality. Yes, it’s a “LINQ to Firebird”, in fact LINQ to Entites connected to Firebird.
Firebird .NET provider has ability to create parameterized queries. Both named and unnamed parameters are supported. Everything works as you expect with select, insert, delete or update commands.
