What is COM+

An extension of Microsoft's Component Object Model (COM) that builds on COM's integrated services and features in key areas, including

  • Dynamic load balancing, which distributes client requests across multiple equivalent COM components
  • In-memory database (IMDB), which provides quicker data access to applications by lowering overhead
  • Publish and subscribe services, which provide an event mechanism enabling multiple clients to subscribe to published events and send notification to subscribers when events are fired
  • Queued components, which let clients invoke methods on COM components using an asynchronous model for increased reliability over poor network connections and in disconnected usage scenarios
  • Integration of Microsoft Transaction Server (MTS) into COM, which supports attribute-based programming, improvements in transactions, security and administration services, and improved interoperability with other transaction environments through support for the Transaction Internet Protocol (TIP)
