Behavioural constraints: Why using events instead of states,IFO. provides a “whole-event” approach for the dynamic modelling of applications (any fact is modelled as an event). As regards the behavioural conditions constraining event triggering, IFO. also provides an event approach, based on traces. In fact, operators are proposed to manipulate traces and ca

Behavior consistent extension of object life cycles, Similarly, different notions of “consistent extension” of object life cycles can be defined to meet various objectives..This paper treats inheritance of object life cycles in the realm of behavior diagrams that identify legal sequences of states and activities (operations). It presents necessary an

Database design with behavior and views using parameterized Petri nets,n stages, both database behavior and the existence of multiple user views of the database. It utilizes the structure and capabilities of parameterized Petri nets (PPNs) described in . Petri nets are traditionally found useful for describing conditions and events that constitute a dynamic system.

Neural network technology to support view integration,ch correspondences may be the source for conflicts when integrating the views and thus must be detected and resolved. A manual inspection of the class definitions in each view and a comparison with each class definition in the other views may result in an almost endless process. To support a designe

Database schema transformation and optimization,lent conceptual schemas often map to different internal schemas, so performance may be improved by applying conceptual transformations prior to the standard mapping. This paper discusses recent advances in the theory of schema transformation and optimization within the framework of ORM (Object-Role

Mapping an extended entity-relationship schema into a schema of complex objects,iented one, and migrating from a conventional database to an object-oriented database containing complex objects. This paper deals with an important step of the migration process by describing a technique for complex entity formation which involves recursively grouping entities and relationships fro

Binary representation of ternary relationships in ER conceptual modeling,nstructs and constraints provided during conceptual entity relationship (ER) modeling..Our paper investigates which ternary relationship cardinality combinations can be losslessly decomposed, which combinations preserve functional dependencies, and whether the logic involved in these processes is su
