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...
Relationship of relationships and other inter-relationship links in E-R model
The concept of relationship has hitherto been defined as an association between entities. This definition is too restrictive and...
GRAQULA: A graphical query language for entity-relationship or relational databases
GRAQULA is a graphical language for querying and updating a database. One version of GRAQULA provides a user interface...
An entity-based approach to query processing in relational databases
An entity-based query interface to relational databases is developed. The interface combines some objectoriented features with the strengths of...
View integration of behavior in object-oriented databases
Database schemas are often not de®ned by a single person but by several future users of the database who...
Analysis of binary/ternary cardinality combinations in entityrelationship modeling
In this paper, we discuss the simultaneous existence, and relationships, between binary and ternary relationships in entity-relationship (ER) modeling....
Hyper-semantic data modeling
This paper describes a new area of data modeling, a model in this new area, and the schema specification...
