Návrh metodiky implementace OLAP jako nástroje pro analýzu metadat emailových zpráv / Methodology of design multidimensional databases in the farm environment

Vasilenko, Alexandr January 2016 (has links)
This dissertation thesis is focused on bulk unsolicited messages which are present in current time in all sectors of electronic communications. It is not only e-mail communication, but also in online forums, discussion contributions, social networking and more. Analyze spam messages is therefore an essential element in preventing flooding user mailboxes. Antispam countermeasures is a set of processes, software tools and methods. It is necessary to harmonize all these components into one cooperating piece of service. Administrators of email servers are trying to keep their servers optimally configured. The problem is that spammers trying continuously these defense mechanisms and filter bypass to enhance spam processes. Their work is very sophisticated and this fight does not yet have a clear winner. After enhancement techniques either processes takes place after a certain time to balance the advantages and disadvantages. For these reasons it is necessary to have a tool which can be analyzed in depth junk messages with dynamic data views. This tool can be Online Analytical Processing (OLAP below), which is very suitable for this purpose. Presented a method of data extraction and transformation and preparation for storage in a warehouse DT-MEZ (Data Pump - metadata email messages). This method is part of the methodology ASOLAP (Antispam - OLAP).

Análise técnica e pedagógica de metadados para objetos de aprendizagem

Silva, Julia Marques Carvalho da January 2011 (has links)
O processo de ensino-aprendizagem visa que sujeitos-professores promovam o ensino a alunos, com o objetivo que eles adquiram um conhecimento. Entretanto, este processo é influenciado por diversas variáveis: estrutura curricular, perfil dos alunos, direção e coordenação pedagógica, corpo docente, comunidade onde estão inseridos, duração e planejamento das aulas, recursos disponíveis, etc. O planejamento permite que o professor organize e estabeleça como as aulas ocorrerão, bem como o tempo necessário, a fim de garantir a aprendizagem. Neste processo, o professor faz uso de recursos didáticos, como mediadores. Dentre as diversas possibilidades de recursos educativos, encontram-se os objetos de aprendizagem. Eles consistem em recursos físicos ou digitais, que tem como diferencial, o uso de um conjunto de metadados com informações relacionadas ao objeto de aprendizagem. Os metadados são arquivos padronizados que seguem especificações que orientam como estes devem estar descritos, de forma a permitir a indexação e recuperação em repositórios. Dentre as especificações para metadados, destacam-se: a Dublin Core, IEEE LOM e OBAA. O Dublin Core é a especificação mais utilizada por repositórios, entretanto, foi desenvolvida para descrever qualquer recurso, sendo educacional ou não. O IEEE LOM é considerada a especificação mais completa, e permite a descrição de objetos de aprendizagem físicos e digitais. O OBAA é uma proposta brasileira que se baseia no IEEE LOM e apresenta como diferencial, por exemplo, a descrição de objetos de aprendizagem multiplataforma e maior detalhamento das características pedagógicas. Os atuais estudos relacionados a objetos de aprendizagem e metadados concentram-se no desenvolvimento e uso destes recursos. Logo, não há pesquisas que relacionem o uso dos metadados como suporte ao planejamento pedagógico. Em face deste cenário, a presente tese investiga como os usuários-professores fazem uso dos metadados no planejamento pedagógico que inclui o uso de objetos de aprendizagem. Ainda, é investigado como os metadados da especificação OBAA auxilia na definição dos requisitos técnicos e pedagógicos, comparado ao Dublin Core e IEEE LOM. Para isto, foi realizada uma pesquisa qualitativa, usando as técnicas de grupo focal e o estudo de casos múltiplos, com a participação de dois tipos de sujeitos: especialistas e usuários professores. A pesquisa com os especialistas foi realizada sob a abordagem do grupo focal não estruturado, onde quatro casos foram analisados e discutidos. Já os usuários-professores participaram dos grupos focais semiestruturado e estruturado. Inicialmente, eles conceitualizaram os termos “recursos didáticos” e “planejamento pedagógico” para então desenvolver planos de aula fazendo uso de objetos de aprendizagem, onde se foi observado como os metadados se fizeram presentes no planejamento. Os resultados obtidos mostraram que a especificação OBAA atende os requisitos técnicos e pedagógicos, embora são propostas algumas modificações. Também foi possível identificar quais metadados realmente auxiliaram os professores no planejamento, destacando os que descrevem o recurso pedagogicamente. Ainda, percebeu-se que a especificação OBAA melhor auxiliou os professores neste processo, e neste sentido, foi proposto um conjunto reduzido de metadados OBAA contemplando os elementos essenciais para a descrição de um objeto de aprendizagem em um repositório e que assista o professor no planejamento. / The teaching-learning process aims to the teachers teach students, in order that they acquire knowledge. However, this process is influenced by several variables: curriculum structure, students background, direction and pedagogical coordination, its community, class duration and lesson planning, resources, etc.. The planning allows the teacher to organize and establish how the classes will occur, and the time necessary to ensure learning. In this process, the teacher makes use of pedagogical resources as mediators. Among the various possibilities of educational resources, are the learning objects. They consist of physical or digital resources, which has the advantage, the use of a set of metadata with information related to the learning object. The metadata files are standardized specifications that follow that guide how they should be described, to allow indexing and retrieval in repositories. Among the specifications for metadata include: the Dublin Core, IEEE LOM and OBAA. The Dublin Core is a specification used by many repositories, however, was developed to describe any resource, and educational or not. The IEEE LOM is considered the most complete specification, and allows the description of physical objects and digital learning. The OBAA a Brazilian proposal is based on the IEEE LOM and has unique features, for example, the description of learning objects and greater detail of multiplatform pedagogical features. The current studies related to learning objects and metadata focus on the development and use of these resources. Thus, there is no research that relate to the use of metadata to support educational planning. Given this scenario, this thesis investigates how users-teachers make use of metadata on educational planning that includes the use of learning objects. In addiction, it is investigated how the metadata specification OBAA assists in defining the technical and pedagogical requirements, compared to the Dublin Core and IEEE LOM. For this, we performed a qualitative study using focus group techniques and the study of multiple cases involving two types of subjects: teacher experts and users. The research was conducted with experts in the focus group approach is not structured, where four cases were analyzed and discussed. The users-teachers participated in semi-structured focus groups and structured. Initially, they conceptualized the term "educational resources" and "lesson planning" and then develop lesson plans using learning objects, which was observed as the metadata were present in the planning. The results showed that the specification meets the technical requirements OBAA and teaching, although some modifications are proposed. It was also possible to identify what metadata really helped the teachers in planning, highlighting that describe the teaching resources. Still, it was realized that the best specification OBAA assisted the teachers in this process, and in this sense, we proposed a reduced set of metadata OBAA contemplating the essential elements for describing a learning object in a repository and to assist the teacher in planning.

[en] A META-TOOL FOR GENERATING DIAGRAMS USED IN THE REVERSE ENGINEERING OF LEGACY SYSTEMS / [pt] UMA META-FERRAMENTA DE GERAÇÃO DE DIAGRAMAS UTILIZADA NA ENGENHARIA REVERSA DE SISTEMAS LEGADOS

RODNEI SILVA COUTO 13 January 2010 (has links)
[pt] A recuperação da documentação relativa à estrutura de um sistema legado visa apoiar o seu entendimento e sua manutenção. Com base em diagramas que descrevem a estrutura do sistema tal como implementado, facilita-se entender o sistema e analisar o impacto de pedidos de mudança. Este trabalho apresenta uma metaferramenta que utiliza metadados para a sua instanciação visando representações específicas. Para avaliar a metaferramenta e o processo de engenharia reversa por ela apoiado foi conduzido um estudo experimental visando a recuperação dos modelos de um sistema legado implementado em PL/SQL. / [en] The recovery of the documentation of the structure of a legacy system aims at supporting its understanding and maintenance. Based on diagrams that describe the structure of the system as it was implemented, it is easier to understand the system and analyze the impact changes may have. This dissertation introduces a meta-tool that uses metadata for its instantiation aiming at specific representations. An experimental study on the recovery of models of a legacy system implemented in PL/SQL was conducted to enable the evaluation of the meta-tool and the reverse engineering process that it supports.
