AMMO-Prot: amine system project 3D-model finder

BACKGROUND: Amines are biogenic amino acid derivatives, which play pleiotropic and very important yet complex roles in animal physiology. For many other relevant biomolecules, biochemical and molecular data are being accumulated, which need to be integrated in order to be effective in the advance of biological knowledge in the field. For this purpose, a multidisciplinary group has started an ontology-based system named the Amine System Project (ASP) for which amine-related information is the validation bench. RESULTS: In this paper, we describe the Ontology-Based Mediator developed in the Amine System Project (http://asp.uma.es) using the infrastructure of Semantic Directories, and how this system has been used to solve a case related to amine metabolism-related protein structures. CONCLUSIONS: This infrastructure is used to publish and manage not only ontologies and their relationships, but also metadata relating to the resources committed with the ontologies. The system developed is available at http://asp.uma.es/WebMediator

Autonomies in a Software Process Landscape

Until now autonomy properties have been mainly discussed in the research area of database management systems, agents and robotic systems. We address these properties to software process models, and distinguish between data autonomy, operation autonomy and communication autonomy. In this paper we develop a classification framework of different granularity levels and different degrees for each of the autonomy types. We analyze the autonomy of an example software process landscape modelled with a Petri based net notation. The example process landscape represents software process models for the development of multimedia applications. Detailed analyses of the example check the classification framework, and consider the impact of autonomy properties on software processes and on software process management

Restrições de integridade e regras ativas em bancos de dados distribuídos

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Computação.Esta dissertação ressalta e analisa uma das possibilidades de aplicação da tecnologia de banco de dados (que é o ambiente distribuído), onde várias instâncias de bancos de dados são interligadas por redes de computadores independentes da localização geográfica, constituindo uma integração transparente e autônoma. Porém, esse ambiente apresenta vários problemas, dentre eles destacamos as restrições de integridade distribuídas, sob os aspectos de definição e de cumprimento das restrições de integridade. Para tanto, admitimos os principais sistemas gerenciadores de banco de dados disponíveis no mercado atualmente (Ingres II, Oracle8i, DB2 v7 e SQL 2000), nos quais analisamos as formas que os mesmos suportam a replicação e distribuição de dados. Ciente das propriedades de replicação e distribuição de dados de cada SGBD, verificamos a maneira pela qual as regras de integridade são concebidas e mantidas por eles. Neste sentido, avaliamos cada SGBD (considerando o domínio de aplicação) em conformidade às respectivas características. Outro modelo investigado neste trabalho, que pode ser adotado como um forte aliado ao cumprimento das restrições de integridade distribuídas, é o paradigma de regras ativas (ECA-Rule)
