Com & .Net Component Services – hinnat ja saatavuus

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.
