Come, let's play: scenario based programming using LSCs and the play engine ; with CD-ROM

Meer over het boek

This book focuses on scenarios of system behavior rather than a traditional narrative. It emphasizes reactive systems, including software, hardware, and computer-embedded systems like distributed and real-time systems. A new programming approach is proposed, centered on inter-object scenario-based behavior. The text introduces a language that extends live sequence charts (LSCs), initially proposed in 1998. Two key techniques are presented: the first, play-in, allows users to 'play in' scenario-based behavior directly from the system's graphical user interface (GUI). The second, play-out, enables the execution or 'play out' of this behavior on the GUI, akin to conventional intra-object state-based programming. This functionality is fully implemented in the Play-Engine tool. The book suggests enhancements for various phases of system development life cycles, such as requirements capture, analysis, prototyping, and testing. More radically, it proposes an alternative programming method for reactivity that aligns closely with how people naturally conceptualize systems and their behaviors.
