Operações sobre arquivos ordenados

Apresentação dos processos inerentes aos arquivos sem ordenação. Nesta animação é ilustrada como é feita a criação de um arquivo sem ordenação. Os processos de criação de arquivo, inserção, remoção, alteração e busca de dados em arquivos sem ordenação são ilustrados em dois níveis: nível conceitual, em que é mostrada a ideia geral; nível detalhado, em que é ilustrado a relação entre o disco HD e a memória buffer.

Mecanismos de segurança para um sistema cooperativo de armazenamento de arquivos baseado em P2P

Previous works have studied the characteristics and peculiarities of P2P networks, especially security information aspects. Most works, in some way, deal with the sharing of resources and, in particular, the storage of files. This work complements previous studies and adds new definitions relating to this kind of systems. A system for safe storage of files (SAS-P2P) was specified and built, based on P2P technology, using the JXTA platform. This system uses standard X.509 and PKCS # 12 digital certificates, issued and managed by a public key infrastructure, which was also specified and developed based on P2P technology (PKIX-P2P). The information is stored in a special file with XML format which is especially prepared, facilitating handling and interoperability among applications. The intention of developing the SAS-P2P system was to offer a complementary service for Giga Natal network users, through which the participants in this network can collaboratively build a shared storage area, with important security features such as availability, confidentiality, authenticity and fault tolerance. Besides the specification, development of prototypes and testing of the SAS-P2P system, tests of the PKIX-P2P Manager module were also performed, in order to determine its fault tolerance and the effective calculation of the reputation of the certifying authorities participating in the system

Bibliotecas, arquivos e museus como centros de referência na dimensão cultural das comunidades

With the evolution of the organizations theory, new management practices have transformed the institutions. The improvement of these management practices in cultural unities (UCs) is constant, and interacts in the international axis, since each unity increasingly communicate with other. As a reflection of organizational administrative practices, UCs had developed and assumed the organizational theories to make easy a framework for effective management practices. Comprehending the importance of the studies on UCs requires both a new approach of existing public politics for this field, and the recognition of the Information Science knowledge on area. In this way, it was planned to develop a model constituting a tool for managers in these institutions through the experience of laboratory works carried out with researchers from the European community. Libraries and museums are institutions that operate in the social process of their communities and the archives establish their structural spaces in parallel with the political, economic and social environments of the communities, translate the society and its organic sphere of informational performance. The information transposes a cyclical and essential role for the arrangement of the effective and necessary record to the organizational process and the institutional growth. Studies of this nature contribute to value a economy based on knowledge, and its production emphasizes the human capital that permeates the condition of the information in support for the development of communities and the growth of the organizational environment in political, social and cultural spheres.
