Distributed object models, mobile computing and electronic commerce

This paper presents an overview of the models, programming paradigms and software tools needed for an integrated network (wired and wireless) computing environment that can support electronic commerce. In particular, it considers the role of various interactive distributed computing models (client server CS, code on demand COD, remote evaluation REV, and mobile agents MA, and three-tier system TTS), different logical modes of programming (imperative, declarative, subjunctive and abductive), transaction and workflow models (that relax atomicity, consistency, isolation, durability and serializability properties), new protocols and software tools (PJava/JDBC/CORBA products) that are needed.
