Software fortresses : modeling enterpise architectures

This book presents a novel approach for modeling large enterprise systems through the software fortress model. In this model, enterprise architecture is conceptualized as a collection of self-contained, mutually suspicious, and marginally cooperating software fortresses that interact via carefully managed treaty relationships. The approach is intuitive and aligns well with existing technologies like .NET and Java 2 Enterprise Edition (J2EE). It aims to define and clarify the fundamentals of this modeling methodology for large enterprise software architectures. Key topics covered include the fundamental concepts and terminology of software fortresses, documentation techniques such as Fortress Ally Responsibility Cards and Sequence Ally Diagrams, and the appropriate use of drawbridges for interoperability. The book also addresses the innovative software fortress model for enterprise security, design strategies for fortress walls and guards, and the significance of loosely and tightly coupled transactions within the architecture. Additionally, it explores design and technology issues related to the six major software fortress types. This work is essential for enterprise software professionals, including managers looking to manage system complexity, architects designing interoperable and secure systems, consultants advising on .NET and J2EE, implementers understanding their systems' roles, and business analysts ensuring successf
