In program slicing, widget-based event-driven programs are different from conventional programs because of their particular features of object construction infrastructure and event-driven mechanism and asynchronous access of global variables. Therefore conventional slicing techniques cannot be applied to widget-based event-driven programs. To solve this problem, this paper first introduces a se...

Flow-Design is a new approach in developing software architectures, which focuses on data processing function units and the communication among them. Event-Based Components represent a programming language independent methodology for implementing Flow-Design and can also be considered as a resulting software architecture. The Event-Based Components software architecture is structured by compone...

Applications are regularly developed by composing functionality encapsulated in units of computation. Depending on the type of system these units of computation, components for short, include modules, classes, and programs. The functionality provided by components can be composed by procedural abstraction and implicit invocation (Garlan & Shaw, 1994; Dingel et al., 1998; Notkin et al., 1993). W...

Today’s software technology was created for applications that used a relatively small number of homogeneous devices. Current applications need to deal with thousands, and in the future perhaps millions, of highly heterogeneous devices. As a result, an active area of research in distributed systems is currently trying to invent software methodologies consisting of communication paradigms, tools,...
