Transformation of UML class diagram into OWL Ontology
- Computer ScienceJ. Inf. Telecommun.
- 2020
This paper will suggest the addition of rules for transforming UML class diagrams to ontologies, such as attribute transformations which have data types as classes, the structured attributes, the association with association class, the recursive association, the aggregation with a qualification.
Forensic attribution challenges during forensic examinations of databases
- Computer Science
- 2018
This dissertation identified a group of database triggers, classified as non-data triggers, which have the potential to contaminate the data in popular relational databases by inconspicuous operations, such as connection or shutdown.
Arquitetura de armazenamento de dados para Sistemas de Informação Geográfica Voluntária utilizando Banco de Dados NoSQL baseado em documento
- Computer Science
- 2016
This work is to specify a data storage architecture for VGIS using NoSQL database that meets requirements of scalability and heterogeneity of data, and analysis of the proofs of concept seeks to verify the viability of the adoption of document-based NoSQL databases as an alternative to a datastorage architecture forVGIS.

EXTENDING TEMPORALLY ER MODEL FOR DESIGNING TEMPORAL DATABASES WITH MULTIPLE TIME GRANULARITIES
- Computer Science
- 2013
The ETER model and temporal normalization theory can be integrated to design temporal databases with multiple time granularities by extending temporally traditional ER models and introducing two new constructs including variety granularity and time cardinality.
A first proposal for a general description model of forensic traces
- Computer SciencePhotonics Europe
- 2012
This paper introduces a first common description model for different forensic trace types and applies for selected trace types from the well established database schema development process the phases of transferring expert knowledge in the corresponding forensic fields into an extendible, database-driven, generalised forensic description model.
A workflow to support forensic database analysis
- Computer Science
- 2012
The research presents a system that allows a forensic examiner to focus on what is relevant to a case in a systematic way that can be proved in court, and proposes a generic workflow of database forensic examination.
Capturing Temporal Constraints in Temporal ER Models
- Computer ScienceER
- 2008
The TimeER model is extended by introducing the notation, and the associated semantics, for the specification of new temporal constraints for time-varying information.
Conceptual Design of an XML FACT Repository for Dispersed XML Document Warehouses and XML Marts
- Computer ScienceThe Fifth International Conference on Computer and Information Technology (CIT'05)
- 2005
This paper proposes a view-driven approach for modeling and designing of a Global XML FACT (GxFACT) repository under the MDA initiatives, and provides three design strategies for building and managing such GxF ACT in the context of modeling of further hierarchical dimensions and/or global document warehouses.
