Overview

Flex 3 is the new version of Adobe technology used to define a runtime and development environment that allows developers to create highly interactive front ends by taking advantage of the already popular Flash Player. Flex 3 applications, classified as a Rich Internet Applications, interact with the Business Logic component via web services, Java public methods (POJO, EJB3, Sprinf, Hibernate) or with HTTP calls with any server side technology (PHP, Coldfusion, .NET, Ruby on Rails) and can be inserted into complex Enterprise architectures (J2EE) guaranteeing aspects such as security and the separation between presentation and logic.
The Flex 3 version enriches SDKs, providing new components to enrich web applications even more, like the new and powerful AdvancedDataGrid, or integration with Flash CS3 and other Adobe Creative Suite 3 products, or even the possibility of exporting the application onto desktop, thereby creating an AIR project.
This course guides students in a step-by-step learning process that begins from the basic notions of Flex 3 and Flex Builder 3 to the development of complex front end applications that communicate with remote data sources.
