  1. Hemera KickOffOctober 5th, 2010 Working Group B5 Efficient management of very large volumes of information for data-intensive applications Gabriel Antoniu, Jean-Marc Pierson

  2. Challenges • Tremendous volumes of data (up to Petabytes), increasing every year • Cloud infrastructures enforce this trend • Large span of diverse applications • Different modalities of data: images, text, video, raw values • Distributed, heterogeneous, structured or not, semantically (en-)riched, confidential • Stored in DFS or DDB, Cloud storage services, Warehouses

  3. Aim of the WG • Explore research issues related to high-level services for information management (search, mining, visualisation, processing) • For large volumes of distributed data • Taking into account • security, efficiency and heterogeneity • applications requirements • and the execution infrastructure (grids, clouds)

  4. Issues to be addressed • Low-level: • Fault-tolerance, caching, transport, security (encryption, confidentiality), consistency, location transparency • Intermediate-level: • Interoperability among storage systems • Data indexing • High-level: • Data mining, data classification, data assimilation, knowledge extraction, data visualization • Metadata management

  5. Communities involved • Distributed applications • Distributed systems • clusters, grids, P2P, clouds • Fault-tolerant systems • Databases, data mining • Security • Numerical algorithms

  6. Roadmap • Identify research teams • Active in the area of the WG • With experience in data-intensive applications on Aladdin-G5K • And new comers… • Organize workshops and possibly schools to share and disseminate experience and knowledge
