Come, Let's Play : Scenario-Based Programming Using LSCs and the Play-Engine PDF
by David Harel, Rami Marelly
Description
This book does not tell a story. Instead, it is about stories. Or rather, in technical terms, it is about scenarios.
Scenarios of system behavior. It con- centrates on reactive systems, be they software or hardware, or combined computer-embedded systems, including distributed and real-time systems.
We propose a different way to program such systems, centered on inter- object scenario-based behavior.
The book describes a language, two tech- niques, and a supporting tool.
The language is a rather broad extension of live sequence charts (LSCs), the original version of which was proposed in 1998 by W.
Damm and the first-listed author of this book. The first of the two techniques, called play-in, is a convenient way to 'play in' scenario- based behavior directly from the system's graphical user interface (QUI).
The second technique, play-out, makes it possible to execute, or 'play out', the behavior on the QUI as if it were programmed in a conventional intra- object state-based fashion.
All this is implemented in full in our tool, the Play-Engine.
The book can be viewed as offering improvements in some ofthe phases of known system development life cycles, e.g., requirements capture and anal- ysis, prototyping, and testing.
However, there is a more radical way to view the book, namely, as proposing an alternative way to program reactivity, which, being based on inter-object scenarios, is a lot closer to how people think about systems and their behavior.
