Introduction to Ruby on Rails

Ruby on Rails is a software package for writing network applications. It's based on a computer software language, Ruby, Provides powerful framework support for program developers. You can write first-class networking software with less code and a lot more time than before.

The guiding principle of Ruby on Rails is "Don't repeat yourself" (Don t Repeat yourself, or dry). It means that the code you write doesn't have to be duplicated. For example, the previous database interface is often similar to the program code, but in many places to be reused. This is costly both for authoring and maintenance. Instead, Ruby on rails gives you the overwhelming majority of support, It allows you to achieve powerful functionality with just a few lines of code. Also, rails provides code generation tools that allow you to implement powerful management programs without even having to write a single line of code.

Ruby on Rails reduces the reliance on configuration files through reflection and runtime extension, which is very different from the direction of the java,c# language, allowing you to reduce the number of configuration and deployment headaches, But the performance is completely able to meet the requirements of the general Web site.
