Bancos de dados normalmente são projetados para atender a um domínio específico de uma aplicação, tornando o acesso aos dados limitado e uma tarefa árdua em relação à integração de bancos e compartilhamento de dados. Existem várias pesquisas no intuito de integrar dados, como a criação de softwares específicos para uma determinada aplicação e até soluções mais radicais como refazer todos os bancos de dados envolvidos, demonstrando que ainda existem questões em aberto e que a área está longe de atingir soluções definitivas. Este trabalho apresenta conceitos e estratégias para a integração de bancos de dados heterogêneos e a implementa na forma do DIGE, uma ferramenta para desenvolver sistemas de banco de dados integrando diferentes bancos de dados relacionais heterogêneos utilizando grades computacionais. O sistema criado permite o compartilhamento de acesso deixando os dados armazenados em seu local de origem, desta forma, usuários do sistema acessam os dados em outras instituições com a impressão de que os dados estão armazenados localmente. O programador da aplicação final pode acessar e manipular os dados de forma convencional utilizando a linguagem SQL sem se preocupar com a localização e o esquema de cada banco e o administrador do sistema pode adicionar ou remover bancos de forma facilitada sem a necessidade de solicitar alterações na aplicação final.; Databases are usually designed to support a specific application domain...

Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.; Introdução: O intercâmbio de registros de autoridade requer o estabelecimento e a adoção de padrões de metadados, tais como o Formato MARC 21 para Dados de Autoridade, formato utilizado por diversas agências catalogadoras, e o Metadata Authority Description Schema (MADS), padrão que permanece pouco explorado pela literatura e pouco difundido entre as agências. Objetivo: Apresentar um estudo introdutório sobre o padrão MADS. Metodologia: Pesquisa bibliográfica descritiva e exploratória. Resultados: São abordados o contexto de criação do MADS...

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Ciência da Computação; Embora XML seja um padrão de fato para o intercâmbio e representação de informações, atualmente observa-se que documentos XML passaram a atuar como verdadeiros containers de dados a serem recuperados pelas aplicações. Como prova disto, sistemas gerenciadores de banco de dados passaram a fornecer meios para a persistência e manipulação de documentos XML. Diante desta nova atuação para este formato de dados, a necessidade de metodologias para a organização de esquemas XML se torna evidente. Diversos trabalhos na literatura fornecem contribuições para o projeto de documentos XML. Entretanto, não existem metodologias completamente adequadas e consolidadas para atuar no projeto de um banco de dados XML. Este trabalho vem ao encontro desta necessidade, provendo uma metodologia para o projeto lógico de banco de dados XML. O foco deste trabalho está no processo de transformação de um esquema conceitual em um esquema lógico XML. A metodologia proposta considera todos os construtores do modelo conceitual EER (Extended Entity-Relationship), bem como as restrições conceituais...

A two-level data transformation consists of a type-level transformation of a data format coupled with value-level transformations of data instances corresponding to that format. We have implemented a system for performing two-level transformations on XML schemas and their corresponding documents, and on SQL schemas and the databases that they describe. The core of the system consists of a combinator library for composing type-changing rewrite rules that preserve structural information and referential constraints. We discuss the implementation of the system’s core library, and of its SQL and XML front-ends in the functional language Haskell. We show how the system can be used to tackle various two-level transformation scenarios, such as XML schema evolution coupled with document migration, and hierarchical-relational data mappings that convert between XML documents and SQL databases.; Fundação para a Ciência e a Tecnologia (FCT) - POSI/ICHS/44304/2002.

Biomedical Text Mining (BioTM) is providing valuable approaches to the automated curation of scientific literature. However, most efforts have addressed the benchmarking of new algorithms rather than user operational needs. Bridging the gap between BioTM researchers and biologists’ needs is crucial to solve real-world problems and promote further research. We present @Note, a platform for BioTM that aims at the effective translation of the advances between three distinct classes of users: biologists, text miners and software developers. Its main functional contributions are the ability to process abstracts and full-texts; an information retrieval module enabling PubMed search and journal crawling; a pre-processing module with PDF-to-text conversion, tokenisation and stopword removal; a semantic annotation schema; a lexicon-based annotator; a user-friendly annotation view that allows to correct annotations and a Text Mining Module supporting dataset preparation and algorithm evaluation. @Note improves the interoperability, modularity and flexibility when integrating in-home and open-source third-party components. Its component-based architecture allows the rapid development of new applications, emphasizing the principles of transparency and simplicity of use. Although it is still on-going...

Various programming languages allow the construction of structure-shy programs. Such programs are defined generically for many different datatypes and only specify specific behavior for a few relevant subtypes. Typical examples are XML query languages that allow selection of subdocuments without exhaustively specifying intermediate element tags. Other examples are languages and libraries for polytypic or strategic functional programming and for adaptive object-oriented programming. In this paper, we present an algebraic approach to transformation of declarative structure-shy programs, in particular for strategic functions and XML queries. We formulate a rich set of algebraic laws, not just for transformation of structure-shy programs, but also for their conversion into structure-sensitive programs and vice versa. We show how subsets of these laws can be used to construct effective rewrite systems for specialization, generalization, and optimization of structure-shy programs. We present a type-safe encoding of these rewrite systems in Haskell which itself uses strategic functional programming techniques. We discuss the application of these rewrite systems for XPath query optimization and for query migration in the context of schema evolution.

This research line covers the topics of genome-scale metabolic model re-construction, biological text mining and metabolic engineering with the ultimate aims of designing improved cell factories for the application in industrial biotechnology processes and of improving our understanding of important human pathogens. In Metabolic Engineering problems, it is often difficult to predict the effects of genetic modifications on the resulting phenotype, owing to the complexity of metabolic networks. Consequently, the task of identifying the modifications that will lead to an improved microbial phenotype is a quite complex one, requiring robust mathematical and computational tools. Part of our effort is therefore dedicated to the generation of better mathematical models of microbial metabolism, applying Bioinformatics tools like Data Mining and Biological Text Mining. We have also developed algorithms for identifying gene knockouts that can improve productivities in strains using stoichiometric metabolic models and have been focusing our attention on the possibility of indicating other genetic modifications such as gene additions and over-expressions. Furthermore, we have developed an open-source software tool, called OptFlux...

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial Technologies; Implementation of the INSPIRE directive, the spatial data infrastructure for the Europe, has created a necessity for easy and convenient conversion between different models of geospatial data. Data model transformation across heterogeneous systems can be hampered by differences in terminology and conceptualization, particularly when multiple communities are involved. Requirement in current situation is an interface facilitating transformation of data to a desired format and immediate use of the data, which are collected from different formats and models. Ontology-aware software with shared understanding of concepts, enable users to interact with geospatial data models. Thus use of ontologies could make a friendly environment to the user in translating the data conveniently. Feature type ontologies, along with annotations are provided from an ongoing project at the Institute for Geoinformatics (IfGI, University of Münster, Germany), in order to reconcile differences in semantics. FME workbench provides a successful environment to execute set of rules for the data model transformation using a mapping file...

The γ-proteobacterium Shewanella oneidensis strain MR-1 is a metabolically versatile organism that can reduce a wide range of organic compounds, metal ions, and radionuclides. Similar to most other sequenced organisms, ≈40% of the predicted ORFs in the S. oneidensis genome were annotated as uncharacterized “hypothetical” genes. We implemented an integrative approach by using experimental and computational analyses to provide more detailed insight into gene function. Global expression profiles were determined for cells after UV irradiation and under aerobic and suboxic growth conditions. Transcriptomic and proteomic analyses confidently identified 538 hypothetical genes as expressed in S. oneidensis cells both as mRNAs and proteins (33% of all predicted hypothetical proteins). Publicly available analysis tools and databases and the expression data were applied to improve the annotation of these genes. The annotation results were scored by using a seven-category schema that ranked both confidence and precision of the functional assignment. We were able to identify homologs for nearly all of these hypothetical proteins (97%), but could confidently assign exact biochemical functions for only 16 proteins (category 1; 3%). Altogether...

SCHEMA structure-guided recombination of 3 fungal class II cellobiohydrolases (CBH II cellulases) has yielded a collection of highly thermostable CBH II chimeras. Twenty-three of 48 genes sampled from the 6,561 possible chimeric sequences were secreted by the Saccharomyces cerevisiae heterologous host in catalytically active form. Five of these chimeras have half-lives of thermal inactivation at 63 °C that are greater than the most stable parent, CBH II enzyme from the thermophilic fungus Humicola insolens, which suggests that this chimera collection contains hundreds of highly stable cellulases. Twenty-five new sequences were designed based on mathematical modeling of the thermostabilities for the first set of chimeras. Ten of these sequences were expressed in active form; all 10 retained more activity than H. insolens CBH II after incubation at 63 °C. The total of 15 validated thermostable CBH II enzymes have high sequence diversity, differing from their closest natural homologs at up to 63 amino acid positions. Selected purified thermostable chimeras hydrolyzed phosphoric acid swollen cellulose at temperatures 7 to 15 °C higher than the parent enzymes. These chimeras also hydrolyzed as much or more cellulose than the parent CBH II enzymes in long-time cellulose hydrolysis assays and had pH/activity profiles as broad...

Could a disjoint group of enzymes synchronize their activities and execute a complex multi-step, measurable, and reproducible response? Here, I surmise that the alpha-ketoglutarate dependent superfamily of non-haem iron (II) dioxygenases could influence cell physiology as a cohesive unit, and that the broad spectra of substrates transformed is an absolute necessity to this portrayal. This eclectic group comprises members from all major taxa, and participates in pesticide breakdown, hypoxia signaling, and osmotic stress neutralization. The oxidative decarboxylation of 2-oxoglutarate to succinate is coupled with a concomitant substrate hydroxylation and, in most cases, is followed by an additional specialized conversion. The domain profile of a protein sequence was used as an index of miscellaneous reaction chemistry and interpreted alongside existent kinetic data in a linear model of integrated function. Statistical parameters were inferred by the creation of a novel, empirically motivated flat-file database of over 3800 sequences (DB2OG) with putative 2-oxoglutarate dependent activity. The collated information was categorized on the basis of existing annotation schema. The data suggests that 2OG-dependent enzymes incorporate several desirable features of a systems level player. DB2OG...

The ability to efficiently transfer information among tactical systems is essential for network-centric operations. However, maintaining interoperability among heterogeneous networks and applications is a challenging issue, especially for large enterprises such as the US Department of Defense and NATO. Each of these organizations maintain extensive communication networks of tactical systems that process and manage all types of data. Additional complexity is added when considering that many systems are built with a variety of proprietary or legacy data formats. Establishing and maintaining interoperability is difficult. Using XML, many interoperability issues can now be successfully addressed. XML provides a self-describing way to effectively structure information that can be applied to compose diverse tactical communications. However, XML is inefficient for network transmission since it uses a text-based format which can consume more memory (and thus more bandwidth) than binary equivalents. In addition, parsing text-based documents is slow and computationally expensive. One potential solution is to use GZIP to reduce the file size before transmission. Unfortunately, this solution has limitations since it often provides suboptimal compression and also requires additional processing time when extracting data. Recent standardization efforts have identified promising new encodings for XML that use binary representations to reduce parsing time...

Nowadays, more than half of the computer development projects fail to meet the final users' expectations. One of the main causes is insufficient knowledge about the organization of the enterprise to be supported by the respective information system. The DEMO methodology (Design and Engineering Methodology for Organizations) has been proved as a well-defined method to specify, through models and diagrams, the essence of any organization at a high level of abstraction. However, this methodology is platform implementation independent, lacking the possibility of saving and propagating possible changes from the organization models to the implemented software, in a runtime environment. The Universal Enterprise Adaptive Object Model (UEAOM) is a conceptual schema being used as a basis for a wiki system, to allow the modeling of any organization, independent of its implementation, as well as the previously mentioned change propagation in a runtime environment. Based on DEMO and UEAOM, this project aims to develop efficient and standardized methods, to enable an automatic conversion of DEMO Ontological Models, based on UEAOM specification into BPMN (Business Process Model and Notation) models of processes, using clear semantics, without ambiguities...

Sistemas de Bancos de Dados Heterogêneos (SBDHs) integram, em um ambiente cooperativo, Sistemas de Bancos de Dados (SBDs) autônomos e heterogêneos entre si, particularmente no que concerne aos modelos de dados utilizados. A transparência de modelos em SBDHs é a propriedade que permite que o usuário visualize as informações segundo um único modelo.de dados e manipule esses dados usando uma única linguagem. Esta dissertação propõe e discute soluções para suportar tal propriedade em SBDHs construídos a partir da integração de SBDs que seguem o modelo relacional ou o modelo rede. Essas soluções incluem metodologias para conversão de esquemas, e arquiteturas e algoritmos para transformação de operações. A abordagem adotada neste trabalho difere da maioria dos trabalhos publicados em dois aspectos. Primeiro, parte do pressuposto que cada usuário vai manipular os dados do ambiente integrado usando a linguagem associada ao modelo de dados utilizado por ele antes da construção do SBDH. Segundo, propõe soluções para permitir que o usuário manipule os dados do SBDH através de programas de aplicação construídos em uma linguagem de propósito geral e não apenas através de operações ad-hoc; Heterogeneous Database Systems (HDBSs) integrate...

The XNAT informatics platform is an open source data management tool used by biomedical imaging researchers around the world. An important feature of XNAT is its highly extensible architecture: users of XNAT can add new data types to the system to capture the imaging and phenotypic data generated in their studies. Until recently, XNAT has had limited capacity to broadcast the meaning of these data extensions to users, other XNAT installations, and other software. We have implemented a data dictionary service for XNAT, which is currently being used on ConnectomeDB, the Human Connectome Project (HCP) public data sharing website. The data dictionary service provides a framework to define key relationships between data elements and structures across the XNAT installation. This includes not just core data representing medical imaging data or subject or patient evaluations, but also taxonomical structures, security relationships, subject groups, and research protocols. The data dictionary allows users to define metadata for data structures and their properties, such as value types (e.g., textual, integers, floats) and valid value templates, ranges, or field lists. The service provides compatibility and integration with other research data management services by enabling easy migration of XNAT data to standards-based formats such as the Resource Description Framework (RDF)...

A aplicação de uma restrição alimentar após o desmame, é recomendada por alguns autores para prevenir a ocorrência de doenças digestivas, cuja incidência é maior em coelhos após o desmame. O principal objectivo deste trabalho foi estudar o efeito do nível de restrição alimentar e do tempo de acesso ao alimentador em alguns parâmetros digestivos do coelho em crescimento. A experiência foi delineada de acordo com um modelo factorial 2×2, onde 4 grupos de doze coelhos com 32 dias de idade foram distribuídos ao acaso, de forma a comparar os efeitos do nível de ingestão de alimento (ad libitum vs. 75% do nível ad libitum) e do tempo de acesso ao alimentador (acesso livre ao alimentador 24h/24 ou acesso não permitido entre as 10h30 e as 16h30). Este maneio foi realizado entre os 32 e os 63 dias de idade e entre os 63 e os 70 dias de idade (abate), todos os animais foram alimentados ad libitum e com livre acesso ao alimentador durante todo o dia. A digestibilidade da dieta, o crescimento dos animais, a ingestão de alimento, o estado sanitário e o ritmo de excreção fecal foram as determinações realizadas neste trabalho. Nos resultados obtidos, não foram encontradas interacções significativas entre o nível de ingestão e o tempo de acesso ao alimentador...

The POOL data storage mechanism is intended to satisfy the needs of the LHC experiments to store and analyze the data from the detector response of particle collisions at the LHC proton-proton collider. Both the data rate and the data volumes will largely differ from the past experience. The POOL data storage mechanism is intended to be able to cope with the experiment's requirements applying a flexible multi technology data persistency mechanism. The developed technology independent approach is flexible enough to adopt new technologies, take advantage of existing schema evolution mechanisms and allows users to access data in a technology independent way. The framework consists of several components, which can be individually adopted and integrated into existing experiment frameworks.; Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 5 pages, PDF, 6 figures.

The "event" concept appears repeatedly when developing metadata models for the description and management of multimedia content. During the typical life cycle of multimedia content, events occur at many different levels - from the events which happen during content creation (directing, acting, camera panning and zooming) to the events which happen to the physical form (acquisition, relocation, damage of film or video) to the digital conversion, reformatting, editing and repackaging events, to the events which are depicted in the actual content (political, news, sporting) to the usage, ownership and copyright agreement events and even the metadata attribution events. Support is required within both MPEG-7 and MPEG-21 for the clear and unambiguous description of all of these event types which may occur at widely different levels of nesting and granularity. In this paper we first describe an event-aware model (the ABC model) which is capable of modeling and yet clearly differentiating between all of these, often recursive and overlapping events. We then illustrate how this model can be used as the foundation to facilitate semantic interoperability between MPEG-7 and MPEG-21. By expressing the semantics of both MPEG-7 and MPEG-21 metadata terms in RDF Schema (and some DAML+OIL extensions) and attaching the MPEG-7 and MPEG-21 class and property hierarchies to the appropriate top-level classes and properties of the ABC model...

We describe a binding schema markup language (BSML) for describing data interchange between scientific codes. Such a facility is an important constituent of scientific problem solving environments (PSEs). BSML is designed to integrate with a PSE or application composition system that views model specification and execution as a problem of managing semistructured data. The data interchange problem is addressed by three techniques for processing semistructured data: validation, binding, and conversion. We present BSML and describe its application to a PSE for wireless communications system design.
