    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

    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
