VPSF: A Parallel Signature File Technique Using Vertical Partitioning and Extendable Hashinghod uses an extendable hashing technique for dynamic environment and uses a frame-sliced signature file technique for efficient retrieval. Our VPSF method also can eliminate the data skew and the execution skew by allocating each frame to a processing node. To prove the efficiency of our VPSF method

A Case for Deltas in Business—to—Business Electronic Commercelication and our software prototype in support of this application. Our main contribution is a software solutions (using Java) that employs the concept of deltas to maintain consistency in a replicated, distributed environment. Our proposed solution strives to be independent of the schema of the bus

Flexible Workflow Management Systems: An Approach Based on Generic Process Modelss a result, the workflow management system is not used to support dynamically changing workflow processes or the workflow process is supported in a rigid manner, i.e., changes are not allowed or handled outside of the workflow management system. This paper addresses this problem and tackles it by us

Object-Based Ordered Delivery of Messages in Object-Based Systemsnd response messages. In this paper, we newly define an object-based precedent relation of messages based on a conflicting relation among requests. Here, only the messages to be ordered in the object-based system are ordered. We discuss a protocol which supports the object-based ordered delivery of

We present a relationship model and the semantics of relationships. The relationship model is complemented with a m
