Uma proposta de processo de produção de aplicações Web

This paper analyzes typical aspects of Web based software production. A case study is carried out to identify how Web applications with high user interactivity and complex functionality must be produced. The results of the case study are confronted with literature’s identified aspects, resulting in a process model which shows the need of the integrated multidisciplinary development and intensive user participation. Finally, limitations of this model are discussed in relation to differents Web application domains.

RECOVERY SOFTWARE REQUIREMENTS IN THE REVERSE ENGINEERING OF LEGACY SYSTEMS

This article proposes a process for the recovery of the requirements of legacy systems using reverse engineering. The goal is to produce a sufficiently complete and updated documentation for the construction of a new system to replace the legacy. The proposed process uses different sources of information for the requirements of the legacy system, in addition to traditional techniques of analysis for its redocumentation. The process is built progressively in successive cycles of execution for its refinement. The main sources of information used in the process are: the existing legacy system documents, the application of black box testing features available in the Human-Human and Human-Machine and the execution traces (logs) produced in the system stimulation. Each of these three sources of information is exploited in research in different subprocesses.

Uma abordagem sistêmica do processo de produção em engenharia web, na fase de concepção

Web applications production presents problems like low quality; non-compliance with deadline and budget, ad-hoc, chaotic and unstructured process. Moreover, different disciplines and knowledge areas, with particular approaches and methodologies, contribute with this type of production. A particular knowledge area named Web Engineering was developed to focus on these questions; however, it is not consolidated yet. This work aims to present guidelines to the definition of the Web applications production process, from a systemic approach, where the different disciplines, roles and activities are correlated, in the conception phase. The research method utilizes tree cases studies and two action-researches to create a theoretical model through analysis of particular situations. The work identifies a design space formed by the dimensions Form, Function, Information and Technology, related to the main disciplines involved in Web applications production: Design, Software Engineering and Communication & Media. According to the design standard used, it is concluded that there is a best fit for the production process, oriented by one or more dimensions of the design space, allowing a quick evolution of the project to the expected quality level.
