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...
Automatic query reformulations for feature location in a modelbased family of software products
No maintenance activity can be completed without Feature Location (FL), which is finding the set of software artifacts that...
Specifying dynamic and deontic integrity constraints
In the dominant view of knowledge bases (KB's), a KB is a set of facts (atomic sentences) and integrity...
Extracting generalization hierarchies from relational databases: A reverse engineering approach
Relational Data Base Management Systems (RDBMS) are currently the most popular database management systems. The relational model is a...
