Ruby on Rails Training

Course details

Ruby on Rails (RoR) is an innovative web application framework that tends to achieve more with less code and effort. This has made RoR one of the most popular web application frameworks and it is being capitalized significantly by the large tech organizations such as Twitter, Slideshare, eBay and so on. The popularity of RoR among the big companies and the enormous earning opportunities (with high pay-scale) has created a huge demand for RoR developers in growing tech industries around the globe. The primary emphasis on simplicity and productivity has positioned this framework differently.
