Component-Based Architecture for e-Gov Web Systems Development

In spite of the wide coverage of Internet and the need for Web systems to support various governmental tasks, the Brazilian state of Mato Grosso do Sul (Central West region) did not have a technological infrastructure which was sufficient to meet these needs in 2001. This led to setting up the Laboratory of Software Engineering (LEDES) at the Department of Computing and Statistics (DCT), the current Computing Faculty (FACOM), at the Federal University of Mato Grosso do Sul (UFMS), which is now collaborating effectively with the state government providing technological solutions, especially in Web sites and Web applications (WebApps). Developing these solutions has made it possible to capture patterns, define flexible architecture and subsequently set up a process of a Software Product Line (SPL) to develop WebApps in e-gov domain, as well as create computational support tools which automatize this process. This paper presents such computational support tools, lessons learnt during the most relevant projects which have been developed since the creation of LEDES, and the architecture for e-gov web systems development, resultant from early experience.
