The two most used design paradigms the traditional client server paradigm and the newer agent based paradigm are discussed in detail stating the how they work technically.
Finally this paper’s comparism includes the relative advantages of both paradigms with research on a practical experimentation of both paradigms using a Java based client server and agent based systems to determine which a better paradigm was.
