Applying COM+

Applying COM+ will help you:

• Develop a thorough grounding in core COM concepts and how these concepts are used to facilitate COM+ services
  
• Understand COM+ service functionality through "what-if" scenarios and extensive Visual Basic, C++, and, at times, J++' code examples
  
• Configure components and their parent COM+ applications using COM+'s Component Services Snap-In
  
• Automate configuration via the COM+ Administration Objects
  
• Write scalable, middle-tier components that can communicate asynchronously and participate in distributed transactions
  
• Write a fully functional resource manager using a Compensating Resource Manager (CRM)
  
• Use COM+ role-based security to allow or prohibit user access to resources
