Features: This book explains the working principles of COM+ and demonstrates how to use it to develop scalable applications. Specific contents include: the characteristics of scalability, why traditional object-oriented methods are not suitable for scalable systems, and the importance of transactions. The book explains how COM+ runtime services are implemented through description tables and causal chains; introduces terms and organizations, and their roles in concurrency control within COM+ processes; additionally, it illustrates transaction flows and their working processes in integrating objects and transactions. The author shows in the book how instant activation and object pooling work together; reveals the importance of HTTP and MSMQ as communication protocols that are significantly better than DCOM; and more importantly, he explains the overall impact of all these elements on the design of COM+-based scalable systems.
