A methodology and tool for top-down relational database design
This paper presents a methodology for logical design of relational schemas and integrity constraints using semantic binary schemas. This...
Conceptual design of object-oriented database schemas using the binary-relationship model
We describe an algorithmic method for transforming a binary-relationship (BR) conceptual schema to an object-oriented (OO) database schema. The...
On mapping natural language constructs into relational algebra through E-R representation
Research on accessing databases in natural language usually employs an intermediate form for the mapping process from natural language...
Descriptive specification of database object behaviour
Traditional database design methodologies are not appropriate for the specific requirements of object-oriented database systems and new database application...
View update in entity-relationship approach
The traditional problem of updating relational databases through views is an important practical problem that has attracted much interest....
Expressiveness in conceptual data modelling
Conceptual data modelling techniques aim at the representation of data at a high level of abstraction. The Conceptualisation Principle...
Support for modeling relationships in object-oriented databases
Modeling real-world applications typically consists of two parts: the representations of entities of interest, and the representations of relationships...
Cardinality constraints in semantic data models
Constraints are central to the notion of a semantic data model. How well a model captures constraints affects its...
Incoherence and subsumption for recursive views and queries in object-oriented data models
Object-oriented data models are being extended with recursion to gain expressive power. This complicates both the incoherence detection problem...
Extending OMT to support bottom-up design modelling in a heterogeneous distributed database environment
We present an extension to the object model of OMT to cope with bottom-up database design. By investigation, it...
