Description
Transactional COM+ explains how COM+ works and shows students how to use the technology to its fullest potential as a framework for developing scalable applications. It examines the theory behind COM+, why traditional object-oriented models are inappropriate for scalable systems, and the importance of transactions. This book goes beyond the rationale behind the technology and the details of its implementation to present practical, concrete guidelines for using COM+ to build applications that scale.
