COURSE OBJECTIVE:
Course Objectives This course aims to provide the delegate with the knowledge to be able to produce simple,object oriented Ruby applications 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. This is an ideal course for anyone who wants to be able to make sense of code,if not actually to produce it.
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.
