Resolving constraint conflicts in the integration of entity-relationship schemas
In this work, we address the problem of constraint conflicts while integrating the conceptual schemas of multiple autonomous databases...
Data model for customizing db schemas based on business policies
One of the goals of data modeling has been to uniquely identify the data semantics of target applications and...
A formal framework for er schema transformation
Several methodologies for semantic schema integration have been proposed in the literature, often using some variant of the ER...
Explaining conceptual models — An architecture and design principles
An important activity in requirements engineering is validation, which is the process of checking whether a model correctly represents...
Extending an object-oriented model: Multiple class objects
Experiences of both researchers and practitioners with the development of object-oriented database systems help us to evaluate the real...
Formal approach to metamodeling: A generic object-oriented perspective
Formal methods and metamodeling are promising ways to cope with the ever increasing size and complexity of modern software...
Associations and roles in object-oriented modeling
We present an extended ER model with entity, role, and association as the basic constructs for object-oriented modeling. The...
Property covering: A powerful construct for schema derivations
Covering is a well-known relationship in semantic and object-oriented models that holds when a class is the union of...
Inheritance graph hierarchy construction using rectangular decomposition of a binary relation and designer feedback
Inheritance is the main theme of schema design for the object-oriented software and object oriented database . It supports...
Towards an object database approach for managing concept lattices
The concept lattice is a conceptual model firstly introduced by Wille in formal concept analysis, a theory of concept...
