An analysis of structural validity in entity-relationship modeling
We explore the criteria that contribute to the structural validity of modeling structures within the entityrelationship (ER) diagram. Our...
Relational database reverse engineering: Algorithms to extract cardinality constraints
This paper presents algorithms which build SQL queries to improve the reverse engineering of relational databases. Our process extracts...
History-based joins: Semantics, soundness and implementation
In this paper we study the use of case history for control structures in workflow processes. History-dependent control offers...
The linguistic level: Contribution for conceptual design, view integration, reuse and documentation
This article presents the linguistic level of KHEOPS, describing its structure and the information it contains. Even though natural...
Constraint acquisition for Entity-Relationship models
We establish search algorithms from the area of propositional logic as invaluable tools for the semantic knowledge acquisition in...
Consistency enforcement in Entity-Relationship and object-oriented models
Integrity Maintenance is considered one of the major application fields of rule triggering systems (RTSs). Whenever a given integrity...
Decomposing relationship types by pivoting and schema equivalence
In the relational data model, the problem of data redundancy has been successfully tackled via decomposition. In advanced data...
View-based model-driven architecture for enhancing maintainability of data access services
In modern service-oriented architectures, database access is done by a special type of services, the so-called data access services...
A survey of database design transformations based on the Entity-Relationship model
At present, the Entity-Relationship (ER) model is the most important paradigm for conceptual database design. Since the model was...
Evolution of entity–relationship modelling
New modelling languages are continually being developed. Some of them are variants of existing ones, others are completely different,...
