An Agent Based Middleware for Uniform Operation in a Heterogeneous Database Environment

Abstract

To operate databases efficiently and effectively in agentbased environment is becoming a big problem. In this paper, we contribute a framework and develop an agentbased middleware with legacy software wrapping view to operate heterogeneous databases in uniform database agent communication language (DBACL). A middleware agent is developed and is run in the same server with a specific database management system. Non-agent application systems can directly access databases as they did before but task agents operate databases by means of those middleware agents with DBACL. From agent viewpoint, the middleware agent is a wrapper of a specific database, which makes database exhibit the agent characteristics in agent -based environment.
