With COM and .NET Component Services, skilled COM developers can leverage their knowledge for the next generation of components to be built for Microsoft's new .NET framework. A primary goal of Microsoft's COM+ is to provide proven design solutions for scalable systems. Assuming experience with classic COM, COM and .NET Component Services focuses on the added services of COM+, including support for transactions, queued components, events, concurrency management, and security. Along the way, it ably demonstrates that COM+ is a masterpiece of design and usability from the ground up--truly a mature set of component services oriented for the middle tier. COM+ provides a foundation for robust, enterprise-wide, mission-critical distributed applications. And it's not limited to Internet applications. You can use COM+ services in the same places as classic COM components: in-house two-tier information systems, client-tier controls, desktop applications, machine control components, and every other conceivable application of COM. COM and .NET Component Services is the first book to stress the importance of learning to use COM+ services for both .NET and COM component-based applications. Since most companies have considerable investment in existing code base and development skills, COM+ can serve as a migration path for companies and developers. Companies can start (or continue) their projects in COM, using COM+ as a supporting platform for component services, and then when the time comes to move to .NET, they can start plugging .NET components seamlessly into the same architecture, reusing and interacting with their existing COM components.

This book introduces a new approach for modeling large enterprise systems: the software fortress model. In the software fortress model, an enterprise architecture is viewed as a series of self-contained, mutually suspicious, marginally cooperating software fortresses interacting with each other through carefully crafted and meticulously managed treaty relationships. The software fortress model is an intuitive, simple, expressive approach that maps readily to existing technologies such as .NET and Java 2 Enterprise Edition (J2EE). This book is designed to meet an immediate need to define, clarify, and explain the basics of this new modeling methodology for large enterprise software architectures. "Software Fortresses is your essential roadmap to all aspects of software fortresses. Key topics include: The fundamental concepts and terminology of software fortressesDocumentation techniques, including Fortress Ally Responsibility Cards (based on Class Responsibility Cards) and Sequence Ally Diagrams (based on UML's Class Sequence Diagrams)The proper use of drawbridges to provide fortress interoperabilityThe innovative software fortress model for enterprise securityCorrect design approaches to fortress walls, which keep intruders out, and to guards, which let allies in.The role of loosely coupled and tightly coupled transactions in a software fortress architectureDesign and technology issues associated with the six major software fortress types This book is a must-read for all enterprise software professionals, whether you are a manager seeking to rein in run-away enterprise system complexity, an architect seeking to design interoperable, scalable, and highly secure systems, aconsultant expected to give advice on how .NET and J2EE fit into the enterprise space, an implementer wanting to understand how your system relates to a larger enterprise architecture, or a business analyst needing to know that your system requirements will be translated into a successful software implementation. 0321166086B12202002

From the award-winning author of The First Rule of Punk comes the story of four kids who form an alternative Scout troop that shakes up their sleepy Florida town. * "Writing with wry restraint that's reminiscent of Kate DiCamillo... a beautiful tale." —Kirkus Reviews, starred review When three very different girls find a mysterious invitation to a lavish mansion, the promise of adventure and mischief is too intriguing to pass up. Ofelia Castillo (a budding journalist), Aster Douglas (a bookish foodie), and Cat Garcia (a rule-abiding birdwatcher) meet the kid behind the invite, Lane DiSanti, and it isn't love at first sight. But they soon bond over a shared mission to get the Floras, their local Scouts, to ditch an outdated tradition. In their quest for justice, independence, and an unforgettable summer, the girls form their own troop and find something they didn't know they needed: sisterhood.
