Enterprise CORBA is a complete blueprint for building large scale CORBA applications with the reliability, scalability, and manageability today's enterprises require -- using technologies in the marketplace today. In this book, three leading developers of large-scale CORBA applications distill their hard-won expertise. Review CORBA fundamentals, architecture, services, and development approaches that are key to enterprise development. Understand crucial database integration and transaction processing issues, including object persistence, and handling long-lived transactions involving human users. Maximize scalability through improved server resource management, load balancing, fault tolerance, component testing, and other means. Finally, discover how CORBA and distributed objects are changing object-oriented software engineering; the strengths and limits of today's tools; and how to use new UML extensions to model your CORBA applications more precisely.
Dirk Slama, Jason Garbis, and Perry Russell are developers at Iona Technologies (Cambridge, MA, and Dublin, Ireland), whose Orbix object request broker leads the market. Jason Garbis Perry Russell
"Enterprise CORBA is not so much about doing things in CORBA as it is about doing things in CORBA that are not easy to do, but that have to be done to make a project deployable. This is refreshing. CORBA technology is deep enough that most books concentrate on what CORBA does and does well. The authors of Enterprise CORBA " - Jack Woehr, Dr. Dobbs Electronic Review of Computer Books
