The Object Management Group (OMG) came out to be mostly known when it comes to metadata handling and processing. Specifically, OMG was organized by a notable group of vendors in 1989 in order to create and design a standard architecture for a network’s “components” or “distributed objects.” As a result, the Common Object Request Broker Architecture (CORBA) was created. CORBA is characterized by a central element called Object Request Broker (ORB), which enables server requests by a client object regardless of exact location for both client object and network server.
Moreover, OMG enables a clear description of metadata format to represent the entire current applications for some essential purposes, such as software modernization, software mining, and software assurance. This particular specification is basically known as the OMG Knowledge Discovery Metamodel (KDM). KDM is defined as a general language-independent intermediate representation that offers an integrated perspective of a whole enterprise application (e.g., Business Rules Mining), which includes data, program flow, and structure.
Generally, most of the middleware products commonly employed by computer industries or companies use CORBA—apparently functions as strategic architecture for distributed objects. Middleware is a common term for any programming use to mediate or “glue together” two current and isolated programs. In most cases, a middleware product allows either in the accessibility and use of several programs from a designated database, or accessibility to other existing databases. Amazingly, there are over 500 member companies under OMG, and are expected to increase further.
