Glossary

BOA: (Basic Object Adapter) One instance of an object adapter (OA). Serves on the server side as a mediator between the ORB and the object implementation. As its name implies, the BOA offers only primitive services. The BOA's specifications were insufficiently precise and led to a lack of portability in view of vendors' augmentation of the standard. In CORBA version 2.1 the BOA was replaced by the POA.

CCM: (CORBA Component Model) An extension of the CORBA object model. Components run in a container, which provides their runtime environment, and express their features and requirements in terms of provided and required interfaces (ports). Applications can then be assembled from components by connecting their ports.
CG: (Conceptual Graph) A knowledge representation technique based on a bipartite graph consisting of concepts and relations. Conceptual graphs allow the representation of arbitrary information in a formalized way. Conceptual graphs are used in Mico for a generic user interface to the DII that allows the invocation of user-definable operations at runtime.
CGI: (Common Gateway Interface) A specification for transferring information between a WWW server and a CGI program. A CGI program is any program designed to accept and return data that conforms to the CGI specification. The program could be written in any programming language, including C, Perl, Java, or Visual Basic.
CORBA: (Common Object Request Broker Architecture) An architecture that enables objects to communicate with one another regardless of what programming language they were written in or what operating system they...
