The COM+ Admin Objects Model

COM+ provides a programming model, the COMAdmin Objects model, to allow you to administer COM+ applications programmatically. Through this programming model, you can perform any tasks that you would perform using the Component Services snap-in. In addition, using the COMAdmin objects, you can also set some configurations that you cannot do by using the Component Services snap-in, such as creating a transient event subscription.

Most programming object models you are familiar with offer a hierarchical representation of the entities they map to. For example, in the Jet Data Access Objects (DAO), you specify a Workspace object through the top-level DBEngine object. Then you call a CreateDatabase() method of the Workspace object to instantiate an instance of the Database object. From there, you can access the table objects, query objects, and so on by calling the appropriate methods of the Database objects. In the Remote Data Access Objects (RDO), you use the Environment, Connection, and Resultset objects to access database objects in a hierarchical manner, using a specific object at a specific hierarchical level. Other examples include ActiveX Data Objects (ADO) and SQL Server Distributed Management Objects (SQL-DMO).
