Technical information is provided on the intended audience, course prerequisites, and covered topics. Course content, prices, and availability are subject to change without notice. Course Audience This course is intended as a practical guide to learning COM+ for use in building three-tier applications that exploit Microsoft’s Windows DNA architecture, using Windows 2000. The course assumes a basic knowledge of VB COM, programming, such as can be obtained from “Programming COM and ActiveX Using Visual Basic”. Course Description The course provides a thorough introduction to the architecture and services of COM+. It includes a substantial case study, which illustrates the use of COM+ in creating a distributed, three-tier application. The course opens with an introduction to the COM+ problem domain of enterprise computing and a discussion of three-tier distributed systems. Then database programming using ActiveX Data Objects (ADO) is covered, enabling the start of implementing the case study. The fundamentals of COM+ architecture are outlined, including context, activation and interception. Transactions are studied in detail, including hands-on implementation of distributed transactions in COM+. The fundamentals of DCOM are studied, including the ability of COM+ to easily “export” an application for running remotely. Security is covered in detail, including an overview of the underlying NT security model, DCOM security, and high-level COM+ security. Microsoft Message Queue is introduced, including the design and implementation of a message queuing application. There is a discussion of Queued Components, which integrate MSMQ into the COM+ programming model. The “publish and subscribe” event model used in COM+ is covered. Web based programming using COM+ is covered, including creation of a three-tiered application using HTTP and Active Server Pages. Techniques for enhancing application scalability are studied, including component load balancing and object pooling. Appendices provide practical background about SQL Server and Windows 2000 administration. Prerequisites Visual Basic programming experience, an understanding of Win32 architecture, knowledge of COM programming using Visual Basic, and basic HTML.
