Peer-to-peer (P2P) technology provides an efficient way for resource distribution, and sharing. While most current P2P systems only support queries over a single attribute which limits the popularity of the P2P technology. Full-blown P2P applications require the efficient resource searching supporting multi-dimensional attributes. In this paper, we propose(More)
—Object-relational mapping (ORM) in computer software is a programming technique for converting data between incompatible type systems in relational databases and object-oriented programming languages. ORM technologies mediates between object oriented architecture system and relational environment; it is a solution for paradigm mismatch. This creates, in(More)
Real-time collaborative editing systems allow a group of users to view and edit the same document at the same time from geographically dispersed sites connected by communication networks. Consistency maintenance in concurrent access of shared objects is one of the key issues in designing these types of systems. This paper proposes a P2P-based locking schema(More)
—With the rapid increase of available information online, especially with the growing popularity of electronic commerce, web data mining is being paid much attention. Combing web data mining and e-commerce has been a hot issue. Following paper focus on how to apply web mining to electronic commerce instead of the plethora or algorithms in data mining. We(More)
—In a CANopen-compliant industrial control system, the master node controls slave nodes (devices) through the corresponding Node-IDs. Though there are some protocols (such as LSS, LMT etc) established for Node-ID assignment, it is not competent for configuring Node-ID for all slaves automatically. In this paper, a new Node_ID binding protocol is proposed.(More)
