Master the principles of object-oriented programming as it is used with the most recent version of ActionScripting. This book is designed to provide readers with an understanding of object-oriented programming, ActionScript 2.0, and the interaction of the two. Section 1 begins with an introduction to ActionScript 2.0 and the specifics of building classes in AS2. Other topics of discussion include adding properties and methods to classes, inheritance, interfaces, inter-object communications, the details and implications of object-oriented design as a process, and working with and building components. Section 2 investigates the server side of applications. In the new Rich Internet Application paradigm, Flash MX 2004 is used as the user interface to an Internet based Client-Server application, and we will frequently need to interact with other server based technologies. Chapters discuss the importance of the server model; specific methods to interact with different server side technologies, including WebServices, XML files, and even simple text files; and the specific ramifications of working with the Flash Communications Server. Section 3 ties all of the concepts presented in the first two sections together by building a single cohesive application. Step-by-step procedures for conceptualizing and building the application are provided along with detailed coverage of how to debug and optimize the application.

Whether you've already made the move to Visual Basic .NET, or you want to know what's in it for you when you do, Expert One-on-One Visual Basic .NET Business Objects will show you the kinds of opportunities that .NET makes available. It will allow you to make clear, informed decisions about the right way to develop your projects, and show you how the trade-off between performance and flexibility can be made successfully.

As well as these, this book contains the author's Component-based, Scalable, Logical Architecture (CSLA .NET), an object-oriented framework that can act as the foundation for a diverse range of enterprise applications, and which you're free to examine, use, and modify for your needs.

This book is an explanation of design patterns as applied to the .NET 2.0 Framework. Some of the patterns are from Design Patterns: Elements of Reusable Object-Oriented Software, and others are from other sources. The focus of this book is not to explicitly define the patterns, but to illustrate the patterns in the context of using them with a programming language like C#, because the original design patterns were illustrated using C++, and there are major differences between that language and .NET and C#.

Why Patterns?
You might be wondering, “Why this book, and why patterns?” Oddly enough, the idea occurred to me while training some students on how to use design patterns. The students were doing their exercises, and I saw one student in particular write code in which the base type was a class and not an interface. I asked him why he was writing code like that, and his response was, “Because that is what I have been doing all this time.” The student’s method was wrong, but his response revealed an interesting perspective: why use an interface when a base class is good enough? Right then, it hit me like a ton of bricks: object-oriented programming, or OOP, can be easier understood when one is first taught patterns.

It has been my experience as a Visual Basic trainer that most people do not have trouble picking up the syntax of the language. What perplexes and frustrates many people are the higher-level concepts of object-oriented programming methodology and design. To compound the problem, most introductory programming books and training classes skim over these concepts or, worse, do not cover them at all. It is my hope that this book fills this void. My goal in writing this book is twofold. First, to provide you with the information needed to understand the fundamentals of programming with Visual Basic. Second and more importantly, to present you with the information required to master the higher-level concepts of object-oriented programming methodology and design.

This book provides you with the information needed to understand how you go about architecting an object-oriented programming solution aimed at solving a business problem. As you work your way through the book, first you will learn how to analyze the business requirements. Next, you will model the objects and relationships involved in the solution design. Finally, you will implement the solution using Visual Basic .NET. Along the way, you will learn the fundamentals of software design, the Unified Modeling Language (UML), object-oriented programming, Visual Basic (VB), and the .NET Framework.

Objective Caml (OCaml) is an open source programming language that allows you to utilize both functional and object-oriented programming. Sporting features such as a robust object system, type safety, and an expansive standard library, OCaml is a language that encourages pragmatic solutions instead of dogmatic ones. Boasting performance on par with the likes of C/C++, and having compilers available for a variety of platforms, including Windows, Unix, Linux, and Mac OS X, enterprise developers should consider adding this powerful language to their repertoire.

Written for experienced programmers, Practical OCaml teaches OCaml in a code-intensive fashion. Readers are encouraged to follow along with most examples using the OCaml top-level (the interactive interpreter), giving them the opportunity to consider the purpose and syntax of each line. The author’s considerable knowledge of the Java, Python, and C++ languages allows him to present the material at a level and perspective that readers hailing from varied programming backgrounds will appreciate.
Language aficionados will be sure to enjoy the occasional digression into tangential topics such as OCaml’s impurities from the functional programming perspective, with thoughts about how to overcome them using mutability, references, and classes.

"Head First Object Oriented Analysis and Design is a refreshing look at subject of OOAD. What sets this book apart is its focus on learning. The authors have made the content of OOAD accessible, usable for the practitioner." Ivar Jacobson, Ivar Jacobson Consulting "I just finished reading HF OOA&D and I loved it! The thing I liked most about this book was its focus on why we do OOA&D-to write great software!" Kyle Brown, Distinguished Engineer, IBM "Hidden behind the funny pictures and crazy fonts is a serious, intelligent, extremely well-crafted presentation of OO Analysis and Design. As I read the book, I felt like I was looking over the shoulder of an expert designer who was explaining to me what issues were important at each step, and why." Edward Sciore, Associate Professor,Computer Science Department, Boston College

Functional and Object Oriented Analysis and Design: An Integrated Methodology teaches students of information systems, software engineering, computer science and related areas how to analyze and design information systems using the FOOM methodology. FOOM combines the object-oriented approach and the functional (process-oriented) approach. It makes a clear distinction between the analysis and design development phases, and enables a smooth transition from the former to the latter. The methodology in Functional and Object Oriented Analysis and Design: An Integrated Methodology is very structured. As a result, it provides step-by-step guidelines on what to do and how to do each of the analysis and design activities. Many examples make the learning and utilization of the methodology easy.

In recent years, object-oriented programming has emerged as the dominant computer programming style, and object-oriented languages such as C++ and Java enjoy wide use in academia and industry. This text explores the formal underpinnings of object-oriented languages to help the reader understand the fundamental concepts of these languages and the design decisions behind them. The text begins by analyzing existing object-oriented languages, paying special attention to their type systems and impediments to expressiveness. It then examines two key features: subtypes and subclasses. After a brief introduction to the lambda calculus, it presents a prototypical object-oriented language, SOOL, with a simple type system similar to those of class-based object-oriented languages in common use. The text offers proof that the type system is sound by showing that the semantics preserves typing information. It concludes with a discussion of desirable features, such as parametric polymorphism and a MyType construct, that are not yet included in most statically typed object-oriented languages.

Taking a standards-based approach to converged services, Architecting the Telecommunications Evolution lays a foundation for a service-oriented architecture in telecommunications. The authors begin by outlining the development of Internet telephony, focusing on how to use the respective benefits of the traditional public switched telephone network (PSTN) and the Internet to create and implement more value-added services. These two eminent specialists then examine services that originate in the Internet and take advantage of PSTN services followed by PSTN-originating services using the Internet. They conclude with a discussion on how this convergence creates smart spaces in the telecoms domain.

In order to properly understand a field, a researcher has to first understand the accumulated knowledge of that field. Micro-architectural design has accumulated knowledge elements that are clearly defined. These elements, such as design patterns, are properly differentiated and generally understood, but other elements such as heuristics, best practices, and others are just vague concepts. Object-Oriented Design Knowledge: Principles, Heuristics and Best Practices provides a unified and global vision about the lesser-defined areas of micro-architectural design knowledge, exposing the main techniques, experiences, and methods in order to help researchers apply these concepts. Understanding the experiences presented in this book will help readers correctly apply design knowledge.
