The structured techniques for systems analysis and design are still the most widely known. One of the alternatives of this technique is the JAD methodology (Joint Application Design). This methodology is an improvement with respect to the existing ones -…

Framework comprehension is a very limiting factor to take full advantage of the benefits that frameworks offer to increase quality and productivity in software development. In this paper, a reverse engineering approach to framework comprehension using the MetaExplorer tool is…

Most of the current hypermedia model life cycles focus in analysis and design issues, ignoring crucial tasks and activities of hypermedia projects. Others do not take care of basic Software Engineering concepts such as planning, physical and logical modeling, validation…

Sharing of behavior is one of the most important features in the Object-Oriented paradigm. The two classical organisations of sharing are classes and prototypes, raising two different models and two families of object oriented languages. It has been largely discussed…

This article describes strategies devised to improve the efficiency of two classical index data structures for parallel textual databases. The design and cost evaluation is effected on top of the bulk-synchronous model of parallel computing. This allows us to compare…

Applying design patterns is considered a helpful technique for designing software systems.
Patterns description, however, results not sufficiently precise providing a weak understanding and making it difficult to be certain when a pattern is being used correctly. We have formally…

During recent years, new software engineering paradigms like component-based software engineering and COTS-based development have emerged. Both paradigms are concerned with reuse and customisation of existing components. The use of COTS software has become more and more important in state-of-the-art…

The development of languages allowing a proper handling of time is important in many areas of computer science because the capability to deal with the notions of change and time are essential to solve their problems.
In the development of…

Requirements capture user needs about a system [KG99]. They stand for those functional and nonfunctional attributes the system must posses to be considered correct. Requirements also dictate how the system should respond to user interaction. Therefore, they play a very…

We proposed her a technique, which can be employed within the methodology know as process reengineering. This technique was applied in a government environment, which included an Information System and Geographical Information System, developed with financial support from The World…
