Relative constraints in ER data models
Practical extensions to the Entity-Relationship (ER) model to support inter-entity constraints, referred to as relative constraints, are described and...
Reconstruction of ER schema from database applications: a cognitive approach
In the Forward Engineering phase, the designer modifies the database conceptual schema and produces a logical and physical schema...
Extracting an entity relationship schema from a relational database through reverse engineering
This paper presents a method for extracting a conceptual schema from a relational database. The method is based on...
Method restructuring and consistency checking for object-oriented schemas
In this paper we present a framework and algorithms for method evolution handling in object-oriented databases. Two levels of...
State-conditioned semantics in databases
Integrity constraints are usually modeled based on the assumption that they are valid in any database state. This approach...
Modelling constraints with exceptions in object-oriented databases
This paper deals with modelling constraints in object-oriented databases, with emphasis given on exceptions. Constraints are restrictions on properties...
Declarative specification of constraint maintenance
Integrity repair is a pragmatic alternative to integrity checking, already proposed by relational and Codasyl standards and supported by...
On the representation of objects with polymorphic shape and behavior
In this paper we present the concept of roles as an extension to object-oriented database models in which identifiable...
A normal form object-oriented entity relationship diagram
A normal form object-oriented entity relationship (OOER) diagram is presented to address a set of OO data modelling issues,...
