Ruby Programming & Ruby on Rails Course Overview Ruby is a high level Interpreted,Object Oriented,rapid development language deployed in many scenarios in the modern world.
This Ruby Programming & Ruby on Rails course is designed to give delegates the knowledge to develop and maintain Ruby applications and Rails based projects. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Course objectives:
Course Objectives This course aims to provide the delegate with the knowledge to be able to produce simple,object oriented Ruby applications,and develop and maintain Rails based projects that exploit all core elements of the language to solve business problems.
TARGET AUDIENCE:
Who will the Course Benefit? Developers who are required to write,maintain and test Ruby applications and projects based on Ruby on Rails.
COURSE PREREQUISITES:
Requirements Delegates attending this course should have some previous programming experience and be able to define general programming concepts including: compilation,execution,variables,arrays,sequence,selection,iteration,functions,objects,and classes. Moreover delegates should be able to navigate the filesystem (on the command line ideally),edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.
