Building Business Objects
is an excellent introduction to the theory of business components used on the enterprise, based on emerging OMG standards for distributed objects. Suitable for the working designer or IS manager, this title offers a valuable vendor-independent guide to the power of business objects.
The principal strength of this text is its introduction to the theory and practice of business objects created with a modeling tool (included on the accompanying CD-ROM) called the Business Object Facility (BOF) Light. The authors first contrast traditional application architecture with the brave new world of applications written with distributed objects. In a series of simple, effective exercises, which can be done by virtually anyone (even without programming expertise), the authors work to create simple business objects needed for a car rental and apartment rental application. They also introduce UML basics for modeling classes. They avoid committing to CORBA or DCOM as technology platforms (though later chapters describe BOF in terms of CORBA services, including support for naming, transactions, and events). A later chapter looks at the advantages of business objects for Internet applications.
By avoiding the CORBA vs. DCOM vendor war, this book achieves a balanced view of component design that will be appreciated by any manager or developer who wants the "big picture" about the advantages of business objects for reuse and reliability. While some of the details here are already a year old (such as the description of the older Java 1.1 standard), this book is still a useful choice for any IS manager or designer who wants a perspective on today's distributed objects. --Richard Dragan

From the Publisher
Business Objects offer an efficient and natural method of capturing everyday business transactions, including customer profiles, inventory, and order taking. The OMG (Object Management Group) is now establishing standards for Business Objects drafted by Oliver Sims and Peter Eeles. This book outlines the specification that the OMG will adopt, and describes how to design Business Objects for new or existing applications. The interaction of Business Objects with CORBA is also discussed. Hncludes CD-ROM with...
