What is ruby on rails? What are its job opportunities in India? Which companies use it in India?

ruby on rails is a Web Development Language. Its is based on the Ruby, which is the language, and runs on Rails which is the web framework. If all this sounds very geeky to you dont worry, RoR is very easy to learn. Not many Enterprises (big companies) use RoR, or PHP(my favorite) to create WEb pages, but they both are used extensively by small web development companies. They both are extremely powerful when it comes to programming for the WEB

RoR is an immature technology that offers the promise of scripts that can create a whole website. I have seen comparision charts showing RoR lines of code at 16 and the equivalent lines of code in Java at 165. A competing technology is called Groovy. Groovy is based on java and is written in java. Ruby On Rails is based on Ruby and has been adopted by Sun. The problem is both scripting languages take a whole new analogy of thinking and programmers are reluctant to incorporate scripting. Try this for example thinking:

def bigMoneyEmp(emps)
threshold = 150
return emps.select(|e| e.salary > threshold)
end
which is kinda like a struct in C, but it isn't. The var salary is declared and used at the same time. This only works if we have a deep understanding of the rules involved to use such a script.

As far as India. I don't know. But, I've read about the school experience over there where some students have the whole java library memorized. Wow!!!! I'm stupid, I have to read up from time to time.

The books available for Grail, RoR, and Groovy few and are just now being published. The online information available is all unorganized and in pieces. Groovy made a splash in 2004, almost died and is now trying to mature itself as Grails.

Ror is not well established so far .U can go for other technologies like J2EE meanwhile
