What technology(ies) and language(s) is Microsoft Navison implemented with/in?

Question

Navision is also known as Microsoft Dynamics NAV.

Answer 1

Navision's application logic is written using a proprietary language called C/AL, which is loosely based on Pascal. It currently offers both a native database option as well as MS SQL Server.

The next version (NAV 2009) will use .NET assemblies served via IIS. C/AL logic will be translated to C# code and deployed to the server.
