Synergy DBL (Data Business Language) is a compiled, imperative programming language designed for business use. The language was originally called DBL; later it was referred to as Synergy Language; as of 2012 the official name is Synergy DBL. It is based on Digital Equipment Corporation’s DIBOL programming language.
DBL has an English-like syntax that was designed to be self-documenting and highly readable, but not verbose. The language is procedural and, since 2007 (version 9.1), object-oriented.[1] Support for Microsoft’s .NET Framework was added in 2010 (version 9.5).[2]
Code is split into two divisions (data and procedure) and uses a rigid hierarchy. The language includes a standard library consisting of 240 built-in subroutines and functions, 10 built-in classes, and 11 APIs that provide functionality such as access to XML from within DBL programs and sending and receiving data via HTTP/HTTPS.
Synergy DBL is cross-platform, with the current version running on all modern Windows platforms (Windows 7/Server 2008 R2 and higher), as well as on HP-UX, IBM AIX, Oracle Solaris, several varieties of Linux and OpenVMS. Applications can be developed on one platform and ported to other platforms.[3]
Traditional DBL is implemented as bytecode, which is executed by the Synergy Runtime. Synergy .NET programs are CLS-compliant and run under the .NET Framework.
DBL is distributed as part of a suite of programming tools sold as Synergy/DE Professional Series by Synergex International Corporation.
