The Object Management Group is a not-for-profit organization that promotes the use of object-oriented technologies. Among other things, it defines the UML and CORBA standards.
CORBA is an acronym for Common ORB Architecture. The phrase common architecture means a technical standard, so CORBA is simply a technical standard for something called an ORB.
In turn, ORB is an acronym for object request broker, which is an object-oriented version of an older technology called remote procedure call (RPC). An ORB or RPC is a mechanism for invoking operations on an object (or calling a procedure) in a different (“remote”) process that may be running on the same, or a different, computer. At a programming level, these “remote” calls look similar to “local” calls. In fact, CORBA makes it possible for a client application written in one programming language, say, Java, to make a remote call to a server implemented in a different programming language, say, C++. This language independence arises because the public interfaces of a server application are defined in an IDL file and CORBA defines mappings from IDL to many programming languages, including C, C++, Java, COBOL, Ada, SmallTalk and Python.
