High availability and disaster recovery: concepts, design, by Klaus Schmidt

By Klaus Schmidt

Businesses and different organisations rely greater than ever at the availability in their details know-how, and such a lot venture serious enterprise methods are IT-based procedures. enterprise continuity is the facility to do enterprise lower than any situations and is a vital requirement smooth businesses are dealing with. excessive availability and catastrophe restoration are contributions of the IT to meet this requirement. and firms might be faced with such calls for to a fair better quantity sooner or later, when you consider that their credits scores could be reduce with no such precautions.Both, excessive availability and catastrophe restoration, are discovered via redundant platforms. Redundancy can and will be carried out on various abstraction degrees: from the undefined, the working method and middleware elements as much as the backup computing middle in case of a catastrophe. This e-book offers standards, strategies, and realizations of redundant structures on all abstraction degrees, and all given examples discuss with UNIX and Linux structures.

Modeling Reactive Systems With Statecharts : The Statemate by David Harel

By David Harel

The e-book offers a close description of a collection of languages for modelling reactive platforms, which underlies the STATEMATE toolset. The strategy is ruled by way of the language of Statecharts, used to explain habit, mixed Activity-charts for describing actions (i.e., the sensible construction blocks-capabilities or gadgets) and the knowledge that flows among them. those languages are used to enhance a conceptual version of the method, which might be mixed with the system's actual, or structural version, defined in a 3rd language-Module-charts. the 3 languages are hugely diagrammatic in nature, constituting full-fledged visible formalisms, whole with rigorous semantics. they're followed by way of a knowledge Dictionary for specifying extra components of the version which are textual in nature.

Designing from Both Sides of the Screen: How Designers and by Ellen Isaacs

By Ellen Isaacs

Written from the views of either a consumer interface fashion designer and a software program engineer, this publication demonstrates instead of simply describes easy methods to construct expertise that cooperates with humans. It starts with a collection of interplay layout ideas that observe to a extensive diversity of know-how, illustrating with examples from the net, computer software program, mobile phones, PDAs, cameras, voice menus, interactive television, and extra. It is going directly to express how those ideas are utilized in perform through the improvement technique -- whilst the suitable layout can clash with different engineering goals.The authors show how their staff outfitted a full-featured quick messenger software for the instant Palm and computer. via this sensible instance, they describe the various refined tradeoffs that come up among layout and engineering objectives. via simulated conversations, they express how they got here to appreciate every one other's ambitions and constraints and located strategies that addressed either one of their wishes -- and eventually the wishes of clients who simply wish their know-how to paintings.

Model-Based Software Performance Analysis by Vittorio Cortellessa, Antinisca Di Marco, Paola Inverardi

By Vittorio Cortellessa, Antinisca Di Marco, Paola Inverardi

Poor functionality is likely one of the major quality-related shortcomings that reason software program tasks to fail. hence, the necessity to deal with functionality matters early throughout the software program improvement procedure is totally stated, and there's a growing to be curiosity within the examine and software program groups in the direction of concepts, tools and instruments that let to control approach functionality issues as an essential component of software program engineering. Model-based software program functionality research introduces functionality issues within the scope of software program modeling, hence permitting the developer to hold on functionality research during the software program lifecycle.

With this booklet, Cortellessa, Di Marco and Inverardi give you the cross-knowledge that permits builders to take on software program functionality matters from the very early stages of software program improvement. They clarify the fundamental recommendations of functionality research and describe the main consultant methodologies used to annotate and rework software program types into functionality versions. To this finish, they move the entire method from functionality primers via software program and function modeling notations to the most recent transformation-based methodologies.

As a consequence, their publication is a self-contained reference textual content on software program functionality engineering, from which diverse aim teams will gain: expert software program engineers and graduate scholars in software program engineering will study either simple innovations of functionality modeling and new methodologies; whereas functionality experts will easy methods to examine software program functionality version building.
