An EER-Based Conceptual Model and Query Language for Time-Series Data data model (ITDM), is based on EER. It includes in it the concept of time and provides necessary constructs for modeling all different types of objects. We then propose a temporal query language for ITDM, that treats both version-based and time-series data in a uniform manner.

Chrono: A Conceptual Design Framework for Temporal Entitiesent can be exploited in time integrity enforcement by using standard DBMS tools, such as referential integrity and triggers. Furthermore, we present a design tool implementing our data model and constraint generation technique, obtained by extending a commercial design tool.

The ultimate objective of this paper is to introduce principles of integration for different classes of semantic and pragmatic representations.

SpringerBriefs in Molecular Scienceties. Our objective is to investigate the consistency of a set of int-cardinality constraints for a database scheme, i.e. the question whether there exists a fully-populated database instance satisfying all the given int-cardinality constraints.

The final result is a web application with a three-tiered architecture, which is implemented in Java with a relational DBMS as object repository.

Diversity Measures for Smart Cities,etrics are proposed in this paper, each of which measures one of the quality factors previously defined. The metrics may be used to evaluate the quality of data models, choose between alternatives and identify areas for improvement.
