What is IDL in CORBA?

IDL, or Interface Definition Language, in CORBA (Common Object Request Broker Architecture) is used to define the interfaces that objects expose to clients in a language-agnostic manner. It allows developers to specify the methods, data types, and exceptions that can be used in remote procedure calls. By using IDL, CORBA facilitates communication between different programming languages and platforms, enabling interoperability in distributed systems. The IDL compiler generates the necessary code stubs and skeletons for various programming languages, streamlining the development process.
