• Lowers the cost of enterprise computing—The DTC provides a sophisticated, low-cost distributed transaction facility for users of networked, commodity-priced PCs and servers.
  
  
• Simplifies application development—DTC transactions greatly simplify the application task of preserving consistency, despite failures that can occur when updating application data.
  
  
• Provides a consistent transaction model—The DTC supports a variety of resource managers, including relational databases, object-oriented databases, file systems, document storage systems, and message queues.
  
  
• Enables software development using distributed software components—The DTC provides a simple, object-oriented application programming interface for initiating and controlling transactions.
  
  

Using the DTC, your applications gain the following performance advantages:

• Application programs can reliably update data residing in two or more resource managers, such as Microsoft SQL Server or Microsoft Message Queuing.
  
  
• Application programs can reliably update data residing in one or more XA-compliant resource managers, such as Oracle, IBM DB2, Informix, Sybase, or Ingres.
  
  
• Application programs can use an OLE Transactions–compliant resource manager, such as Microsoft SQL Server or Microsoft Message Queuing, with an X/Open-compliant transaction processing monitor such as Encina, TopEnd, or Tuxedo.
  
  
• Application programs can perform transactions spanning multiple transaction managers communicating via the Transaction Internet Protocol (TIP).
  
  
• Windows application programs can invoke IBM CICS transaction programs through the COM Transaction Integrator (COMTI).
