Tiered architecture for remote access to data sources
Teamwork is benefited by the use of shared data sources. Also, ever increasingly, organizational work depends on the activities of team members situated in different physical locations, including both employees who work from their homes and others who have been temporarily transferred to another place.
Since, for all these reasons, accessing data remotely is a growing need, organizations implement internal systems in order to control shared data access according to user privileges. In this regard, the cost of resource transportation needed to generate communication must be considered. The main contribution of this paper is the extended reference layered architecture ICDFSCV (Interface Control and Distributed File Systems - Communication Versioning). It allows to build a solution that, facilitates documents download and the creation and concurrent modification by multiple users through versioning control.Facultad de Informátic

Versioning of Digital Objects in a Fedora-based Repository
This presentation gives an overview on the complex versioning re-quirements for digital objects in the scope of the project eSciDoc and discusses our solution based on the flexible repository architecture Fedora. It describes the conceptual background of how the eSciDoc infrastructure handles versioning of digital objects. Versioning and object identification are strongly interwoven concepts. Therefore, the unique identification of objects and their versions are discussed as well
Online cooperation learning environment : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Computer Science at Massey University, Albany, New Zealand
This project aims to create an online cooperation learning environment for students who study the same paper. Firstly, the whole class will be divided into several tutorial peer groups. One tutorial group includes five to seven students. The students can discuss with each other in the same study group, which is assigned by the lecturer. This is achieved via an online cooperation learning environment application (OCLE), which consists of a web based J2EE application and a peer to peer (P2P) java application, cooperative learning tool (CLT). It can reduce web server traffic significantly during online tutorial discussion time
Criação de interfaces hierárquicas para acesso a redes ontológicas de ficheiros
Dissertação de mestrado integrado em Engenharia de ComunicaçõesOs sistemas de gestão documental são cada vez mais comuns, permitindo uma
grande vantagem para quem normalmente lida com informação, pois possibilitam
um acesso facilitado e rápido a essa informação. Actualmente os sistemas de gestão
documental tentam implementar uma organização de dados que consiga reflectir
ao máximo as relações que estão inerentes à informação no mundo real. Como
se pode verificar no nosso dia a dia a informação usada está repleta de relações,
que com o passar do tempo tornam-se cada vez mais complexas, e os sistemas de
gestão documental reflectem isso de modo a poder organizar a informação do modo
mais fiel e completo possível. Os sistemas de gestão documental mais completos
armazenam os documentos e também as relações a eles inerentes, usando para isso
uma organização ontológica. Estas organizações de dados (ontológicas) conferem
relações qualitativas entre os documentos.
Apesar das vantagens no uso de estruturas ontológicas, os utilizadores estão
mais familiarizados com as estruturas hierárquicas tornando-se intrínseco e inseparável
à experiência do computador pessoal. No entanto, as estruturas hierárquicas
não permitem ter relações qualitativas entre os documentos, o que acontece nas
estruturas ontológicas.
É neste contexto que esta dissertação é realizada, descrevendo como é feita a
transformação duma organização de dados não hierárquica numa hierárquica e os
possíveis problemas que possam aparecer na interligação das operações realizadas
sobre os dados.The systems of document management are becoming more and more common,
being a great advantage for those who usually have to deal with information, since
they enable accessing that same information in an easy and quick way. Nowadays,
the systems of document management are trying to implement a data organization
that is able to reflect the relationships inherent to information in the real world as
much as possible. As it is possible to see in our daily life, the information used is
full of relationships, which become more complex as time goes by, and the systems
of document management reflect that in order to enable to organize information
a way that is as faithful and complete as possible. The most complete systems
of document management store both documents and the relationships inherent to
them by using an ontological organization. These data organizations (ontological)
enhance qualitative relationships between documents.
Despite the advantages of using ontological structures, the users are more familiarized
with the hierarchical structures, thus becoming intrinsic to and inseparable
from the experiment of the personal computer. Nevertheless, the hierarchical structures
do not enable qualitative relationships between documents, as it happens with
ontological structures.
It is within this realm that this dissertation is made, describing how the transformation
of a non-hierarchical data organization into a hierarchical one is made as
well as the possible problems that can appear in the interconnection of the operations
made on data
