Business Process Management
€ 47.99 *
ggf. zzgl. Versand

Business process management is usually treated from two different perspectives: business administration and computer science. While business administration professionals tend to consider information technology as a subordinate aspect in business process management for experts to handle, by contrast computer science professionals often consider business goals and organizational regulations as terms that do not deserve much thought but require the appropriate level of abstraction. Mathias Weske argues that all communities involved need to have a common understanding of the different aspects of business process management. To this end, he details the complete business process lifecycle from the modeling phase to process enactment and improvement, taking into account all different stakeholders involved. After starting with a presentation of general foundations and abstraction models, he explains concepts like process orchestrations and choreographies, as well as process properties and data dependencies. Finally, he presents both traditional and advanced business process management architectures, covering, for example, workflow management systems, service-oriented architectures, and data-driven approaches. In addition, he shows how standards like WfMC, SOAP, WSDL, and BPEL fit into the picture. This textbook is ideally suited for classes on business process management, information systems architecture, and workflow management. This 2nd edition contains major updates on BPMN Version 2 process orchestration and process choreographies, and the chapter on BPM methodologies has been completely rewritten. The accompanying website www.bpm-book.com contains further information and additional teaching material.

Programming in D
€ 35.99 *
ggf. zzgl. Versand

The main aim of this book is to teach D to readers who are new to computer programming. Although having experience in other programming languages is certainly helpful, this book starts from the basics. D is a multi-paradigm system programming language that combines a wide range of powerful programming concepts from the lowest to the highest levels. It has C-like syntax and static typing. It pragmatically combines efficiency, control, and modeling power, with safety and programmer productivity in mind. Each chapter is based on the contents of the previous ones, introducing as few new concepts as possible. It is recommended that the book is read in linear fashion, without skipping chapters if possible. Although this book was written with beginners in mind, it covers almost all features of D. More experienced programmers can use the book as a D language reference by starting from the index section. Blurbs from the back cover: ´´D is pristine, clean, immensely powerful, and arguably the actual state-of-the-art programming language. Ali´s book is a gem. Clear, concise, and complete.´´ - Olivier Henley ´´I have been using Ali´s online D book to teach D at the university level. It is up-to-date, complete, and most importantly, extremely readable. Having a print version is even better! This is now the ´go-to´ book for learning D programming.´´ - Chuck Allison, Professor and Chair, Computer Science Department, Utah Valley University ´´Ali´s explanations are succinct and on target. I like that he provides rationale for why D was designed in a particular way and how I can use it most effectively. This is the best computer language book I´ve read.´´ - Robbin Carlson, Luthier and Enterprise Architect ´´I taught a CS2 Data Structures class in D with more success and student appreciation than when using either C++ or Java as it´s an ideal language to express the relevant concepts at all scales, from detailed to big picture, without needless complexity. Ali Çehreli´s tutorial played a central role supporting students especially during the first half of the course - without it the course simply would not have worked, so ´´many thanks Ali´´ - and an important part of that is its linearity - it can be read with only backward dependencies. This meant that with hard work even students of little experience and only moderate current abilities could get up to speed, and we saw just that. It is hard to overstate this factor. I unreservedly recommend this book to all.´´ - Dr. Carl Sturtivant, University of Minnesota Department of Computer Science & Engineering ´´This book is one of the best guides through the language that I´ve seen.´´ - Andrew Wray, D Enthusiast ´´I encourage anyone considering D to read this book. Not exactly ´D for Dummies´ but it´s easy to follow even if you don´t have much experience with compiled languages.´´ - bachmeier, Reddit user ´´Having worked through the book, I have to say this is one of the easiest to follow and distraction free read there is and the fact that it made learning a new language a total breeze really impressed me.´´ - Imran Khan, Student

Working Effectively with Legacy Code
€ 41.99 *
ggf. zzgl. Versand

Proven strategies for maintaining and optimizing legacy code to get the most out of your existing applications. Examples in C-sharp, C++, and Java, as well as strategies for better using the industry standard modeling language: UML 2.0 Addresses the very concrete problems that programmers face working in the context of large untested code bases Based on successful classes for Object Mentor, the author helps organizations maintain older systems rather than go to the cost of developing new ones This book provides programmers with the ability to cost effectively handle common legacy code problems without having to go through the hugely expensive task of rewriting all existing code. It describes a series of practical strategies that developers can employ to bring their existing software applications under control. The author provides useful guidance about how to use these strategies when refactoring or making functional changes to code bases. One of the book´s key points is that it teaches developers to write tests that can be used to make sure they are not unintentionally changing the application as they optimize it. Examples are provided in Java, C++, and Csharp, and the book assumes that the reader has some knowledge of UML notation. Strategies using UML and code in C++ and Java primarily while language independent advice will be delivered in side bars and appendices for language specific users.

Backcover Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts. In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include Understanding the mechanics of software change: adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform-with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren´t object-oriented Handling applications that don´t seem to have any structure This book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes. © Copyright Pearson Education.

Now, there?s a go-to reference for everyone who wants to start creating accurate and useful system models with SysML. Drawing on his pioneering experience creating models for Lockheed Martin and NASA, Lenny Delligatti illuminates SysML?s core components, and shows how to use them even under tight deadlines and other constraints. You needn?t know all of SysML to create effective models: SysML Distilled quickly teaches what you do need to know, and helps you deepen your knowledge incrementally as the need arises. Coverage includes: How SysML extends and improves UML, and how to immediately put it to practical use How to use SysML as a foundation for Model-Based System Engineering (MBSE) or Model-Based Engineering (MBE) What to know before you start an SysML modeling project How to use key SysML diagrams for block definitions, internal blocks, use cases, activities, sequences, state machines, parametrics, requirements, and packages How to use allocations to define cross-cutting relationships And much more ? including appendices presenting complete SysML notation, identifying changes between SysML versions, and identifying authoritative sources for more information Product Description The Systems Modeling Language (SysML) extends UML with powerful systems engineering capabilities for modeling a wider spectrum of systems and capturing all aspects of a system?s design. SysML Distilled is the first clear, concise guide for everyone who wants to start creating effective SysML models. (Drawing on his pioneering experience at Lockheed Martin and NASA, Lenny Delligatti illuminates SysML?s core components and provides practical advice to help you create good models and good designs. Delligatti begins with an easy-to-understand overview of Model-Based Systems Engineering (MBSE) and an explanation of how SysML enables effective system specification, analysis, design, optimization, verification, and validation. Next, he shows how to use all nine types of SysML diagrams, even if you have no previous experience with modeling languages. A case study running through the text demonstrates the use of SysML in modeling a complex, real-world sociotechnical system. Modeled after Martin Fowler?s classic UML Distilled, Delligatti?s indispensable guide quickly teaches you what you need to know to get started and helps you deepen your knowledge incrementally as the need arises. Like SysML itself, the book is method independent and is designed to support whatever processes, procedures, and tools you already use.
