Ruby On Rails

Audience

Developers who wish to utilise RUBY, RAILS, and the SQL language to develop internet front-end interfaces to relational database back-end objects.

Prerequisites

Experience with at least one other application development language is necessary. Prior exposure to object-oriented principles is desirable. Prior experience with SQL and some RDBMS is also desirable.

Duration

4 days. Hands on.

Course Objectives

This course provides a comprehensive study of the RUBY language, including practical and progressive “hands-on” workshops. It also studies the RAILS application development, testing, and deployment environment for creation of internet applications which view and update relational database data. At the end of this course, delegates will have a clear understanding of how to use the RUBY language. They will have knowledge and experience with RUBY in the RAILS environment (RoR) to quickly implement and test both simple and moderately complex applications.
