Groovy/Grails for Programmers

Course: GRAIL

Duration: 5 Days

Level: II

Course Summary

This course teaches the student Object Oriented Development, the Groovy language, and the Grails Web Development Framework. Through lecture with Q&A, the student will learn how to create applications for current technology. The workshops will reinforce what they have learned and let them practice and apply the technology. Techniques will be used to bridge Cobol, C, Java, and PL/SQL experience to the Groovy/Grails development tasks and syntax. Incremental and Iterative programming practices will be included to insure successful application of the topics after course completion.
