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...
Temporal features of class populations and attributes in conceptual models
Constraints play an important role in conceptual modeling. In general, the specification of constraints, both static and transition, must...
Managing schema evolution using a temporal object model
The issues of schema evolution and temporal object models are generally considered to be orthogonal and are handled independently....
Distributed object repositories: concepts and standards
Object technology in general and object frameworks in particular are influencing the evolution of enterprise modeling, software development tool...
Extended SQL support for uncertain data
Although the relational model for databases provides a great range of advantages over other data models, it lacks a...
Reducing Algorithms for Materialized View Updates
Materialized views, which are used for such as data warehousing, have to be consistent with their original data. They...
