A formalization of the Binary Object-Role Model based on logic
This paper proposes a formalization of the Binary Object-Role Model (B-ORM) based on a general logical formalism for data...
The intentional relationship of representation between the constructs of a language and reality
Specifications of conceptualisations (ontologies) are often employed for representing reality, both in knowledge representation and software engineering. While languages...
Consistency in model integration
State-of-the-art systems engineering uses many models reflecting various aspects of the modeled system. A major task of system engineers...
The operational semantics of user-defined relationships in object oriented database systems
In semantic data models, abstract relationship (e.g. generalization, aggregation, etc.) semantics are defined, specifying how insertion, deletion and modification...
A conceptual design aid environment for expert-database systems
With the actual penetration of expert systems into the business world, the question is, how the expert system idea...
A framework for object migration in object-oriented databases
This article presents a framework developed for accommodating various object migrations in 'statically-typed' object databases. Requirements for supporting object...
Improved model management with aggregated business process models
Contemporary organizations invest much efforts in creating models of their business processes. This raises the issue of how to...
Constructing target-aware results for keyword search on knowledge graphs
Existing work of processing keyword searches on graph data focuses on efficiency of result generation. However, being oblivious to...
Database design with user-definable modelling concepts
Modelling is an integral part of engineering processes. Consequently, database design for engineering applications should take into account the...
Semantic schema refinements for multilevel schema integration
Within the database field, schema refinements have been proved useful for documentation and maintenance purposes; moreover, schemata describing the...
