We investigate two different use cases: a) In the domain of plant phenotyping, there has recently been increasing interests in finding diverse data coming from different research communities. b)In botany, the emergence of citizen sciences has fostered the creation of large and structured communities of nature observers. In this context, there is a need to retrieve diverse plant observations from a diverse spectrum of plant families, genus and species. In this talk I will present some new issues of profile diversity, a novel idea in searching and recommending scientific items (e.g. documents, images, datasets, etc), and how profile diversity can be deployed in different kinds of infrastructures (centralized and distributed).<\/p>\n<p>Titulo: CloudMdsQL: Querying Heterogeneous Cloud Data Stores with a Common Language (Prof. Patrick Valduriez, Inria, Montpellier, France)<br \/>\nThe blooming of different cloud data management infrastructures, specialized for different kinds of data and tasks, has led to a wide diversification of DBMS interfaces and the loss of a common programming paradigm. In this talk, we present the design of a Cloud Multidatastore Query Language (CloudMdsQL), and its query engine. CloudMdsQL is a functional SQL-like language, capable of querying multiple heterogeneous data stores (relational and NoSQL) within a single query that may contain embedded invocations to each data store\u2019s native query interface. The query engine has a fully distributed architecture, which provides important opportunities for optimization. The major innovation is that a CloudMdsQL query can exploit the full power of local data stores, by simply allowing some local data store native queries (e.g. a breadth-first search query against a graph database) to be called as functions, and at the same time be optimized, e.g. by pushing down select predicates, using bind join, performing join ordering, or planning intermediate data shipping. Our experimental validation, with three data stores (graph, document and relational) and representative queries, shows that CloudMdsQL satisfies the five important requirements for a cloud multidatastore query language.<\/p>\n<p>[1] Work partially funded by the European Commission under the Integrated Project CoherentPaaS [3].<\/p>\n<p>Joint work with Boyan Kolev and Carlyna Bondiombouy (Inria, Montpellier), Ricardo Jim\u00e9nez-Peris (UP Madrid), Raquel Pau (Sparcity, Barcelona), Jos\u00e9 Pereira (Inesc, Braga)<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>&nbsp;<\/p>\n<p>A Prof. Esther Pacitti co-lidera a equipe Zenith de Montpellier e\u00a0 tem como pesquisa principal a gerencia de dados distribu\u00eddas: replica\u00e7\u00e3o, processamento de consultas etc. Ela tamb\u00e9m est\u00e1 envolvida nas pesquisas de <em>data-intensive scientific<\/em> workflows sobre nuvens geograficamente distribu\u00eddas.<\/p>\n<p>Patrick Valduriez \u00e9 pesquisador senior do INRIA, liderando a equipe Zenith de Montpellier.\u00a0 O foco da pesquisa \u00e9 em ger\u00eancia de dados em larga escala em sistemas paralelos e distribu\u00eddos (P2P, cluster, grid, cloud),em particular, na ger\u00eancia de dados cient\u00edficos.\u00a0 Ele \u00e9 autor\/coautor de mais de 250 artigos cient\u00edficos e diversos livros, dentro os quais o \u201c<em>Principles of Distributed Database Systems<\/em>\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>No dia 18 de agosto, \u00e0s 10h, teremos a honra de receber os Professores Esther Pacitti e Patrick Valduriez, ambos do Inria, Montpellier, France para proferirem palestras na \u00e1rea de Banco de Dados.
