CORBA Common Object Request Broker Architecture CORBA defines the ORB: a way to call an object “method” wherever the object is In the same process In another process In a process running somewhere on the network CORBA also defines services available for all objects (naming, notification, event) 31/12/2018

CORBA CORBA allows mixing languages: a client is not necessarily written in the same language as the server CORBA uses an Interface Definition Language (IDL) CORBA defines bindings between IDL and the computing languages (C++, Java, Python, Ada, ….) 31/12/2018

Tango and CORBA Tango encapsulates the CORBA communication protocol Allows the use of other communiction protocols Tango uses a narrow CORBA interface All objects on the network have the same interface Allows the use of generic applications Avoids recompilation when new objects are added 31/12/2018
