Agile Software Engineering Skills

This program will provide a better teaching and learning experience—for you and your students. Here’s how:

• Improve Results with MyFinanceLab: MyFinanceLab delivers proven results in helping students succeed and provides engaging experiences that personalize learning.
• Guide Students with a Proven Learning Goal System: Integrating pedagogy with concepts and practical applications, this system presents the material students need to make effective financial decisions in a competitive business environment.
• Provide Real, Hands-on Examples and Connections: Personal finance connections, international considerations, and Excel® spreadsheet practice help students identify and apply concepts in their daily lives.

Recognizing that most programmers will ultimately be applying these techniques in an object-oriented programming (OOP) context, Gill adopts a programming style (e.g., use of very small functions, dividing projects into separate files, creating functions to perform specific operations on structures) that fits nicely with typical OOP approaches.

Drawing on extensive research and practical development experience in VoIP from its earliest stages, the authors give access to all the relevant standards and cutting-edge techniques in a single resource.

IP Telephony: Deploying Voice-over-IP Protocols:

• Assumes a working knowledge of IP and networking and addresses the technical aspects of real-time communication over IP.
• Presents a high level overview of packet media transport technologies, covering all the major VoIP protocols – SIP, H323 and MGCP
• Details specific strategies to design services for public networks where endpoints cannot be trusted and can be behind firewalls.
• Explores the problems that may arise from incomplete protocol implementations, or architectures optimized for private networks which fail in a public environment.

This amply illustrated, state-of-the art reference tool will be an invaluable resource for all those involved in the practical deployment of VoIP technology.

This edition includes more of a focus on the business applications of the concepts. Emphasis has been placed on securing corporate information systems, rather than just hosts in general. Keep Your Course Current and Relevant: New examples, exercises, and research findings appear throughout the text.

Provides the latest in systems analysis and design, including:

• Expanded coverage of business processes. Process modeling is at the heart of systems analysis and design. Data flow diagrams have been a staple of this book since its first edition, but now they are framed in the context of business process diagramming. The beginning of Chapter 6 has been rewritten to show how data flow diagrams are just one of many common methods for modeling business processes. Business processes are defined and illustrated before the discussion of data flow diagrams begins.
• Updated illustrations of technology. Screen captures have been updated throughout the text to show examples using the latest versions of programming and Internet development environments, and user interface designs.
• Updated content. Throughout the book, the content in each chapter has been updated where appropriate.
