Foreign keys form one of the most fundamental constraints for relational databases. Since
they are not always defined in existing databases, the discovery of foreign keys turns out to …

An input to the conceptual database design phase contains a description of the target
database. This description is usually given in some natural language, for instance in …

Functional dependencies (FDs) and inclusion dependencies (INDs) convey most of data
semantics in relational databases and are very useful in practice since they generalize keys …

Defining appropriate integrity constraints (ICs) for the domain model of a software system is
a complex and error-prone task. Both over-constraining and under-constraining the …

Due to the complexity ofmo dern database applications, semantic information is no longer a
unified whole, but arises from multiple sources. Whatever the type of the sources …

We establish search algorithms from the area of propositional logic as invaluable tools for
the semantic knowledge acquisition in the conceptual database design phase. The …

Conceptual modelling is a widely applied practice and has led to a large body of knowledge
on constructs that might be used for modelling and on methods that might be useful for …

Extended Entity Relationship Diagrams are an important step in information system design
and software engineering. In the early seventies Peter Chen developed an efficient …

In our previous publication (Cai, et. al., 2005), we demonstrated the ability to generate the
proper mix of jitter on ATE to enable the jitter tolerance test for 1.5/3Gbps SATA applications …

SQL designs result from methodologies such as UML or Entity-Relationship models,
description logics, or relational normalization. Independently of the methodology, sample …
