Object Technology


Book Description

"The first edition set a standard of excellence that has eluded all followers, and I have recommended it to my clients for years. The new edition is a gift to the field and should be required reading for all managers." - Adrian J. Bowles, Ph.D., Vice President Giga Information Group "One of the most readable introductions you will find. The new edition offers vital insights into the effective use of objects in business." - Chris Stone, President Object Management Group The first edition of "Object Technology: A Manager's Guide" is widely viewed as the classic introduction to this powerful computing concept. Object technology offers increased agility, significant time-to-market reduction, and the opportunity to exploit the potential of the World Wide Web by deploying globally distributed business systems. At a time when many of the world's largest companies are making the transition to object technology, David Taylor has updated his book to address the important issues facing the growth of object technology and to provide a glimpse into the future of this evolving paradigm. In updating this seminal work, David Taylor has retained the signature conciseness and, clarity of discussion that made the first edition a best-seller. "Object Technology: A Manager's Guide, Second Edition," covers the key terms, emerging concepts, and useful applications of objects. Managers, salespeople, engineers, software developers-anyone interested in understanding or implementing object technology-will find this a lucid introduction to the topic. Highlights of this new edition include: An explanation of how to use objects to create evolutionarysoftware that rapidly adapts to changing business conditions, eliminating the need for most new application development. An introduction to Java, and an explanation of how its useof message interfaces enables a new generation of portable, mix-and-match, Internet-enabled business objects. An update on the state of object databases and extended relationaldatabases, with guidelines for combining the two for optimal informationstorage. An introduction to the new generation of object engines andhow they combine storage and execution capabilities for maximumsoftware integration. 0201309947B09102001







Patterns of Enterprise Application Architecture


Book Description

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them. The topics covered include · Dividing an enterprise application into layers · The major approaches to organizing business logic · An in-depth treatment of mapping between objects and relational databases · Using Model-View-Controller to organize a Web presentation · Handling concurrency for data that spans multiple transactions · Designing distributed object interfaces

Business Component Factory


Book Description

In this book, Peter Herzum and Oliver Sims present a complete component based strategy, the business component approach, that applies and extends component thinking to all aspects of the software life cycle for enterprise systems. The approach includes a conceptual framework that brings components into the world of scalable systems, and outlines the different component granularities. It also includes a methodology that goes beyond current object-oriented practices to provide the concepts required to meet the real challenges of component-based development. Using their business component approach, the authors then provide a blueprint for a business component factory--a development capability that can produce software with the quality, speed, and flexibility needed to match changing business needs. Sprinkled with guidelines, tips, and architectural patterns, this book fully prepares you for the approaching component revolution. Praise for Business Component Factory ". . . this book should be very useful for anyone considering the daunting task of adopting component software on an enterprise scale."-Clemens Szyperski (Microsoft Research), Author of the award-winning book, Component Software: Beyond Object-Oriented Programming "Herzum and Sims do an admirable job of differentiating the different component concepts, allowing this clearly written book to focus on the construction of business systems by non-software practitioners, out of business component parts developed separately (and perhaps for a commodity component marketplace). This is the future of software systems, and this book is a practical, giant step in that direction."-Richard Mark Soley, PhD,Chairman and CEO, OMG "Finally, a book that takes you from component design all the way down to the middleware on which they are deployed. It?s an important contribution to the nascent server-side component discipline written by practitioners for practitioners."-Robert Orfali, Author of Client/Server Survival Guide, Third Edition and Client/Server Programming with Java and CORBA, Second Edition (both from Wiley)




Domain Modeling Made Functional


Book Description

You want increased customer satisfaction, faster development cycles, and less wasted work. Domain-driven design (DDD) combined with functional programming is the innovative combo that will get you there. In this pragmatic, down-to-earth guide, you'll see how applying the core principles of functional programming can result in software designs that model real-world requirements both elegantly and concisely - often more so than an object-oriented approach. Practical examples in the open-source F# functional language, and examples from familiar business domains, show you how to apply these techniques to build software that is business-focused, flexible, and high quality. Domain-driven design is a well-established approach to designing software that ensures that domain experts and developers work together effectively to create high-quality software. This book is the first to combine DDD with techniques from statically typed functional programming. This book is perfect for newcomers to DDD or functional programming - all the techniques you need will be introduced and explained. Model a complex domain accurately using the F# type system, creating compilable code that is also readable documentation---ensuring that the code and design never get out of sync. Encode business rules in the design so that you have "compile-time unit tests," and eliminate many potential bugs by making illegal states unrepresentable. Assemble a series of small, testable functions into a complete use case, and compose these individual scenarios into a large-scale design. Discover why the combination of functional programming and DDD leads naturally to service-oriented and hexagonal architectures. Finally, create a functional domain model that works with traditional databases, NoSQL, and event stores, and safely expose your domain via a website or API. Solve real problems by focusing on real-world requirements for your software. What You Need: The code in this book is designed to be run interactively on Windows, Mac and Linux.You will need a recent version of F# (4.0 or greater), and the appropriate .NET runtime for your platform.Full installation instructions for all platforms at fsharp.org.




Business Object Design and Implementation


Book Description

Over the past 10 years, object technology has gained widespread acceptance within the software industry. Within a wider context, however, it has made little impact on the core applications which support businesses in carrying out their tasks. This volume contains a collection of papers establishing the need for Business Objects, with particular reference to work undertaken by the Object Management Group (OMG). The emphasis is on defining an agenda for establishing Business Object standards and architectures, for developing software technology to support Business Objects applications and managing object oriented development projects. The wide variety of papers presented, and their authors' expertise, make this book a significant contribution to the development of Business Objects and their management.




Practical Object-oriented Design in Ruby


Book Description

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution.
