Description

Dissertação de mestrado em Engenharia de Informática Over the last decade component-based software development arose as a promising paradigm to deal with the ever increasing complexity in software design, evolution and reuse. Such components typically encapsulate a number of services through a public interface which provides limited access to a private state space, paying tribute to the nowadays widespread object-oriented programming principles. This work is based on the calculus developed by L.S. Barbosa over several years and it aims at helping the development of formal software component solutions and to explain how they can be related, reducing their complexity. SHACC is a prototyping system for component-based systems in which components are modeled coinductively as generalized Mealy machines incorporating the ideas above. The prototype is built as a HASKELL library endowed with a graphical user interface developed in Swing.
