This chapter gives an overview of how MICO implements the CORBAspecification, the implementation components it consists of,and how those components are used.

A CORBA implementation consists of the following logicalcomponents:

• The Object Request Broker (ORB) provides for object locationand method invocation.
• The Interface Repository (IR) stores runtime type information.
• One or more object adapters form the interface between objectimplementations and the ORB. MICO provides the BasicObject Adapter (BOA) and Portable Object Adapter (POA).The implementation repository stores information about howto activate object implementations.
• The IDL compiler generates client stubs, server skeletons,and marshalling code from a CORBA IDL according to thesupported language mappings.
