A multi-level view model for secure object-oriented databases
In this paper, we employ the view model given by Bertino to design a secure multi-level object-oriented database system....
A system for the semiautomatic generation of E-R models from natural language specifications
Techniques that allow a program to generate E-R models for small application domains are described. The inputs to the...
Towards a formal semantics and inference rules for conceptual data models
A new-from a theoretical point of view-approach to expressing data- or knowledge base semantics is described: the universe of...
Extending ERD modeling notation to fuzzy management of GIS data files
Geographic information systems manage a wide variety of data. Some of these data are stored in traditional databases, but much...
Efficient data retrieval and manipulation using Boolean entity lattice
This paper proposes a technique to organize the database such that retrievals and manipulations will be operated on a...
An ontology based approach to the integration of entity–relationship schemas
In schema integration, schematic discrepancies occur when data in one database correspond to metadata in another. We explicitly declare...
On the design and maintenance of optimized relational representations of entity-relationship schemas
A method for obtaining optimized relational representations of database conceptual schemas in an extended entity-relationship model is first proposed....
Default databases: Extending the approach of deductive databases using default logic
Extending the relational data model using classical logic to give deductive databases has some significant benefits. In particular, classical...
Conceptual language for statistical data modeling
We describe a new language for statistical data modeling. The language offers a general framework for the representation of...
Entity-relationship and object-oriented data modeling – an experimental comparison of design quality
We compare EER and OO data models from the point of view of design quality. Quality is measured in...
