Which type of middleware is used for connecting software components that are written in different programming languages?

Object-oriented middleware is used to connect software components written in different

programming languages by:

Language Interoperability: Enables objects created in one language to be used in another, typically

through CORBA (Common Object Request Broker Architecture) or DCOM (Distributed Component

Object Model).

Distributed Systems: Facilitates communication between objects over a network.

Platform Independence: Abstracts the underlying communication protocols.

Example Use Case: A Java application calling methods on a C++ object using CORBA.

Other options analysis:

A . Transaction processing middleware: Manages distributed transactions, not language

interoperability.

B . Remote procedure call middleware: Calls functions on remote systems but does not focus on

language compatibility.

C . Message-oriented middleware: Transmits messages between applications but does not inherently

bridge language gaps.
