CORBA (Common Object Request Broker Architecture) is a middleware technology that facilitates communication between applications across different platforms and languages, acting as a mediator for seamless interaction. It provides features like transparent communication, naming and security services, and uses Interface Definition Language (IDL) for language-neutral object interface specifications. While it enhances interoperability and code reusability, CORBA comes with challenges such as performance overhead and limited support in modern development environments.

MIDDLEWARE
TECHNOLOGY FOR ENABLING COMMUNICATION BETWEEN APPLICATIONS
ON DIFFERENT
PLATFORMS AND PROGRAMMING LANGUAGES.

6. •
• CLIENT
• SERVER
• REQUEST AND REPLY PROTOCOLS

7. • CORBA AS A MEDIATOR:
CORBA ACTS LIKE A FRIENDLY MEDIATOR OR MESSENGER.
WHEN ONE PROGRAM (LET'S CALL IT PROGRAM A) WANTS TO TALK TO ANOTHER
PROGRAM (PROGRAM B), CORBA HELPS THEM COMMUNICATE.
 TRANSPARENT COMMUNICATION:
PROGRAM A DOESN'T NEED TO KNOW EXACTLY WHERE
PROGRAM B IS OR HOW IT DOES ITS JOB. CORBA HANDLES ALL THE DETAILS,
MAKING THE COMMUNICATION FEEL LIKE BOTH PROGRAMS ARE RIGHT NEXT TO
EACH OTHER, EVEN IF THEY ARE FAR APART.
• FLEXIBILITY AND INTEROPERABILITY:
CORBA ALLOWS PROGRAMS WRITTEN IN DIFFERENT
LANGUAGES OR RUNNING ON DIFFERENT COMPUTERS TO WORK TOGETHER
SEAMLESSLY.

8. • NAMING SERVICE:
 A SERVICE FOR NAMING AND LOCATING OBJECTS IN A DISTRIBUTED ENVIRONMENT.
ALLOWS OBJECTS TO BE GIVEN HUMAN-READABLE NAMES
• SECURITY SERVICE:
 PROVIDES MECHANISMS FOR SECURING COMMUNICATION AND DATA IN A
DISTRIBUTED ENVIRONMENT.
 ADDRESSES AUTHENTICATION, AUTHORIZATION, CONFIDENTIALITY, AND INTEGRITY
TO PROTECT AGAINST UNAUTHORIZED ACCESS AND DATA TAMPERING.
• INTERFACE DEFINITION LANGUAGE (IDL):
A LANGUAGE-NEUTRAL SPECIFICATION USED TO DEFINE THE INTERFACES OF CORBA
OBJECTS.
IT ALLOWS DEVELOPERS TO DEFINE OBJECT INTERFACES INDEPENDENTLY OF
PROGRAMMING LANGUAGES

9. • CORBA AS A MESSENGER:
CORBA IS LIKE A FRIENDLY MESSENGER THAT HELPS THESE WORKERS COMMUNICATE.
IT'S THE ONE PASSING MESSAGES BETWEEN THEM
• PASSING THE MESSAGE:
CORBA THEN DELIVERS THE MESSAGE TO THE WORKER THAT CAN HELP.
THE WORKERS DON'T NEED TO KNOW WHERE EACH OTHER IS; CORBA TAKES CARE OF
FINDING THEM
• WORKING TOGETHER SMOOTHLY:
OVERALL, CORBA HELPS THESE WORKERS FROM DIFFERENT PLACES
AND WITH DIFFERENT JOBS WORK TOGETHER SMOOTHLY, MAKING THE WHOLE SYSTEM RUN
EFFICIENTLY.
• DIFFERENT LANGUAGES, NO PROBLEM:
EVEN IF THESE WORKERS SPEAK DIFFERENT "LANGUAGES"
(PROGRAMMING LANGUAGES), CORBA HELPS THEM UNDERSTAND EACH OTHER.

10. • VISIBROKER:
• DESCRIPTION: VISIBROKER IS AN ORB DEVELOPED BY MICRO FOCUS. IT
PROVIDES SUPPORT FOR MULTIPLE PROGRAMMING LANGUAGES, INCLUDING JAVA
AND C++
• TAO (THE ACE ORB):
• DESCRIPTION: TAO IS AN OPEN-SOURCE CORBA IMPLEMENTATION DEVELOPED
BY THE ACE (ADAPTIVE COMMUNICATION ENVIRONMENT) PROJECT. TAO IS
DESIGNED TO WORK SEAMLESSLY WITH THE ACE FRAMEWORK AND SUPPORTS
MULTIPLE PROGRAMMING LANGUAGES.
• ORBIX:
• DESCRIPTION: ORBIX, DEVELOPED BY IONA TECHNOLOGIES, IS A CORBA
IMPLEMENTATION THAT SUPPORTS MULTIPLE PROGRAMMING LANGUAGES.

11. SECURITY
• CONFIDENTIALITY:
PROTECT DATA FROM UNAUTHORIZED ACCESS

ENSURE THAT DATA IS NOT TAMPERED WITH DURING
TRANSMISSION.
• SECURITY CONTEXTS:
ESTABLISH A CONTEXT FOR SECURE COMMUNICATION BETWEEN
CLIENTS AND SERVERS.

12. • PERFORMANCE OVERHEAD:
CORBA ADDS SOME EXTRA STEPS WHEN
PROGRAMS TALK TO EACH OTHER.
• LEARNING CURVE:
IT TAKES TIME FOR PROGRAMMERS TO UNDERSTAND
HOW TO USE CORBA EFFECTIVELY. IT'S LIKE LEARNING A NEW GAME WITH
LOTS OF RULES
• LIMITED SUPPORT IN MODERN DEVELOPMENT:
M SOME NEWER WAYS OF BUILDING SOFTWARE MIGHT NOT WORK WELL
WITH CORBA. IT'S LIKE USING AN OLD COMPUTER IN A WORLD THAT'S MOVED ON
TO NEW TECHNOLOGY.

13. 
• COMMUNICATION HARMONY:
CORBA HELPS DIFFERENT COMPUTER PROGRAMS WRITTEN IN
DIFFERENT LANGUAGES
LOCATION INDEPENDENCE:
CORBA ALLOWS PROGRAMS TO TALK, NO MATTER WHERE THEY
ARE.
• REUSABILITY OF CODE:
ONCE A PROGRAM DOES SOMETHING WELL, CORBA LETS OTHERS
REUSE ITS SKILLS.
• SCALABILITY SUPERPOWER:
CORBA WORKS WELL WHEN YOU HAVE A LOT OF PROGRAMS OR
TASKS TO MANAGE

14. CORBA ACTS LIKE A FRIENDLY MIDDLEMAN THAT HELPS DIFFERENT
COMPUTER PROGRAMS COMMUNICATE SEAMLESSLY. IT'S AKIN TO A
TRANSLATOR, ENSURING THEY UNDERSTAND EACH OTHER'S LANGUAGE AND
COLLABORATE EFFECTIVELY.
