The Object Oriented Enterprise

A business-oriented, practitioner's guide to creating an object-oriented DBMS for the real world. It covers all the fundamental building blocks of object-oriented databases, detailing how they work and how programs and objects interact. It's packed with proven techniques for modeling and designing effective systems, including many coding examples.

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

Enterprise modeling is the primary tool used in business re-engineering. Historically, the number one problem with enterprise modeling has been the lack of formalism. Getting Results with the Object-Oriented Enterprise Model tackles this dilemma head-on and prescribes a formal methodology based on object technology. This book will help create a reliable enterprise model by assessing the enterprise's current operations as well as its future operations. Developing the model within the context of object-orientation will provide an ideal framework as each object will represent a behavior that is analogous to the issues addressed within the model and the enterprise itself. Getting Results with the Object-Oriented Enterprise Model will then help the reader prioritize and execute the changes suggested by the model. The authors synthesize paradigms from conceptual modeling, information theory, computer theory and business theory to develop a comprehensive and formal description of the enterprise that works. By combining their considerable expertise in both IT and business theory, the authors are able to define the rigorous methodology needed to successfully model any enterprise.

CD-ROM contains: Java and XML implementations of ideas and models described in the appendix.

The continual evolution of object oriented technologies creates both opportunities and challenges. However, despite the growing popularity of object oriented technology, there are numerous issues that have contributed to its inability to firmly entrench itself and take over for the older, proven technologies. Object oriented technology's image problem has created a highly difficult decision making process for corporations considering widespread adoption of these technologies. Object Oriented Technologies: Opportunities and Challenges addresses concerns, opportunities and technology trends in the application of object oriented technologies. The chapters of this book were selected to represent a variety of perspectives concerning the present and future of this broad sub-field of software development.

At the time of writing (mid-October 1998) we can look back at what has been a very successful ECOOP’98. Despite the time of the year – in the middle of what is traditionally regarded as a holiday period – ECOOP'98 was a record breaker in terms of number of participants. Over 700 persons found their way to the campus of the Brussels Free University to participate in a wide range of activities. This 3rd ECOOP workshop reader reports on many of these activities. It contains a careful selection of the input and a cautious summary of the outcome for the numerous discussions that happened during the workshops, demonstrations and posters. As such, this book serves as an excellent snapshot of the state of the art in the field of object oriented programming. About the diversity of the submissions A workshop reader is, by its very nature, quite diverse in the topics covered as well as in the form of its contributions. This reader is not an exception to this rule: as editors we have given the respective organizers much freedom in their choice of presentation because we feel form follows content. This explains the diversity in the types of reports as well as in their lay out.
