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...
The representation of rules in the ER model
Production rules are the most commercially popular and successful structure for representing knowledge. The purpose of this paper is...
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...
