Web Development Frameworks Ruby on Rails VS Google Web Toolkit
Bachelor thesis Web Development Frameworks Ruby on Rails VS Google Web Toolkit Author: Carlos Gallardo Adrián Extremera Supervisor: Welf Löwe Semester: Spring 2011 Course code: 2DV00E SE-391 82 Kalmar / SE-351 95 Växjö Tel +46 (0)772-28 80 00 [email protected] Lnu.se/dfm Abstract Web programming is getting more and more important every day and as a consequence, many new tools are created in order to help developers design and construct applications quicker, easier and better structured. Apart from different IDEs and Technologies, nowadays Web Frameworks are gaining popularity amongst users since they offer a large range of methods, classes, etc. that allow programmers to create and maintain solid Web systems. This research focuses on two different Web Frameworks: Ruby on Rails and Google Web Toolkit and within this document we will examine some of the most important differences between them during a Web development.

Fiz: a Component Framework for Web Applications
Fiz: A Component Framework for Web Applications John K. Ousterhout Department of Computer Science Stanford University Abstract Fiz is a framework for developing interactive Web applications. Its overall goal is to raise the level of programming for Web applications, first by providing a set of high-level reusable components that simplify the task of creating interactive Web applications, and second by providing a framework that encourages other people to create addi- tional components. Components in Fiz cover both the front-end of Web applications (managing a browser-based user interface) and the back end (managing the application's data). Fiz makes it possible to create components that encapsulate complex behaviors such as Ajax-based updates, hiding many of the Web's complexities from applica- tion developers. Because of its focus on components, Fiz does not use mechanisms such as templates and model- view-controller in the same way as other frameworks. ger and more useful structures. We will release Fiz in 1 Introduction open-source form and hope to build a user community Although the World-Wide Web was initially conceived that creates an ever-increasing set of interesting com- as a vehicle for delivering and viewing documents, its ponents, which will make it dramatically easier to cre- focus has gradually shifted from documents to applica- ate applications that advance the state-of-the-art in Web tions.

Ruby on Rails™ Tutorial: Learn Web Developments with Rails
ptg8286261 www.it-ebooks.info Praise for Michael Hartl’s Books and Videos on Ruby on RailsTM ‘‘My former company (CD Baby) was one of the ﬁrst to loudly switch to Ruby on ptg8286261 Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on RailsTM Tutorial is what I used to switch back to Rails again.’’ —From the Foreword by Derek Sivers (sivers.org) Formerly: Founder, CD Baby Currently: Founder, Thoughts Ltd. ‘‘Michael Hartl’s Rails Tutorial book is the #1 (and only, in my opinion) place to start when it comes to books about learning Rails. It’s an amazing piece of work and, unusually, walks you through building a Rails app from start to ﬁnish with testing. If you want to read just one book and feel like a Rails master by the end of it, pick the Ruby on RailsTM Tutorial.’’ —Peter Cooper Editor, Ruby Inside www.it-ebooks.info ‘‘Grounded in the real world.’’ —I Programmer (www.i-programmer.info), by Ian Elliot ‘‘The book gives you the theory and practice, while the videos focus on showing you in person how its done. Highly recommended combo.’’ —Antonio Cangiano, Software Engineer, IBM ‘‘The author is clearly an expert at the Ruby language and the Rails framework, but more than that, he is a working software engineer who introduces best practices throughout the text.’’ —Greg Charles, Senior Software Developer, Fairway Technologies ‘‘Overall, these video tutorials should be a great resource for anyone new to Rails.’’ —Michael Morin, ruby.about.com ‘‘Hands-down, I would recommend this book to anyone wanting to get into Ruby on Rails development.’’ —Michael Crump, Microsoft MVP ptg8286261 www.it-ebooks.info RUBY ON RAILSTM TUTORIAL Second Edition ptg8286261 www.it-ebooks.info Visit informit.com/ruby for a complete list of available products.
