October 25, 2010, 11:13 AM — In the world of enterprise programming, the mainstream is broad and deep. Code is written predominantly in one of a few major languages. For some shops, this means Java; for others, it's C# or PHP. Sometimes, enterprise coders will dabble in C++ or another common language used for high-performance tasks such as game programming, all of which turn around and speak SQL to the database.
Programmers looking for work in enterprise shops would be foolish not to learn the languages that underlie this paradigm, yet a surprising number of niche languages are fast beginning to thrive in the enterprise. Look beyond the mainstays, and you'll find several languages that are beginning to provide solutions to increasingly common problems, as well as old-guard niche languages that continue to occupy redoubts. All offer capabilities compelling enough to justify learning a new way to juggle brackets, braces, and other punctuation marks.

While the following seven niche languages offer features that can't be found in the dominant languages, many rely on the dominant languages to exist. Some run on top of the Java Virtual Machine, essentially taking advantage of the Java team's engineering. And when Microsoft built C#, it explicitly aimed to make the virtual machine open to other languages. That detail may help make deployment easier, but it doesn't matter much to the programmer at creation time.
Either way, these seven languages are quickly gaining converts in the enterprise. Perhaps it's time to start investigating their merits.
