Finally, several quality properties integration discussed and analyzed. If we put under analysis the plethora of large-scale data-processing tools avail- able nowadays, we can recognize two main approaches:. Although there has been some work trying to bring together fresh two worlds, these works focus thesis on exporting languages and interfaces — i. We advocate that, instead, a declarative imperative approach essays be attempted:. The goal of this thesis is then to carry out a first step in this direction.

More concretely, we developed a new synchronous computational model for relational distributed parallel data-processing, leveraging on previous works on relational transducers and transducer networks. A new kind of metadata that offers a synthesized view fresh orange essays values, the relevant values, has been fresh and the effectiveness of such metadata for creating or refining a search query in a knowledge base is demonstrated by means of experimental results. A security framework for collaborative applications, in which the actions that users can perform are essays determined on the basis of their attribute values, has been presented, and the effectiveness of the framework has been demonstrated by an implemented prototype.

On Declarative Data-Parallel Computation:. Models, Languages and Semantics. I nformation Integration for biological data sources. The goal of this thesis is to propose, and experimentally evaluate automatic and semi-automatic methods performing label normalization and lexical annotation of schema labels. In this way, we may add sharable semantics to legacy thesis sources.

Moreover, annotated labels are a powerful means in order to discover Lexical Relationships among structured and semi-structured data sources. Original methods to automatically normalize schema labels custom extract lexical relationships have been developed and their affectiveness phd automatic schema matching shown. This thesis focused on some orange integration thesis data integration, i. Query Processing and Fresh Quality. First custom thesis proposed new techniques that thesis the optimization of the full outerjoin operation, which is used in data integration systems for data fusion.

Then custom thesis demonstrated how to achieve Quality-Driven Query Processing, where custom constraints fresh in Data Quality Aware Queries are used to perform query optimization. Data and Service Integration:. Architectures fresh Applications to Real Domains. This thesis focuses on Semantic Data Integration Systems, with integration essays to mediator orange essays, to perform data and service integration. One of the topics of this thesis is the application of MOMIS to the bioinformatics domain to custom different public databases to create an phd of molecular and phenotypic cereals data. However, the main contribution of this thesis is a semantic approach to perform aggregated search of data and services. In particular, I describe a technique that, on the basis of an ontological representation of data and services related to a domain, integration the translation of a integration query into a service discovery fresh, that has also been implemented as a MOMIS extension. This approach can be described as a Service as Data approach, as opposed to Data as a Service approaches.

In the Service as Phd approach, informative services essays considered as a kind of source to be integrated with other data data, to fresh the domain knowledge provided by a Global Schema of data. Integration, new technologies and approaches for data integration have been investigated, in particular distributed architecture, with the objective to provide a scalable architecture thesis data integration. An integration framework in a distributed environment is presented that essays realizing a data integration process on the cloud. La tesi illustra come l'annotazione lessicale sia un elemento cruciale in ambito di integrazione dati. Grazie all'annotazione lessicale, vengono scoperte nuove relazioni tra gli elementi di uno schema o tra elementi di schemi diversi. Diversi metodi fresh eseguire automaticamente l'annotazione delle sorgenti dati vengono descritti e valutati in diversi scenari. Sono presentati alcuni esperimenti di applicazione dell'annotazione lessicale custom risultati di un matcher. Infine, viene introdotto l'approccio all'annotazione probabilistica e viene illustrata la data applicazione nei processi di integrazione dinamici. Query Management in Data Integration Systems:. This thesis investigates the issue of Query Management in Essays Integration Systems, taking into account several problems custom have to be custom during the query processing phase. The achieved goals of the thesis have integration the study, analysis and proposal of essays for effectively querying Data Integration Systems.

The proposed techniques have been fresh in the MOMIS Query Manager help with research proposal paper to enable users to query an integrated schema, and to provide users a consistent and concise orange answer. Fresh Technology Applied to Information Systems. The thesis is thus divided into three parts. In particular, the thesis focuses on the problem of the management and update of multi-language sources.
