Problem Statement
Data Management
Voluminous information (scalability)
Storage
Linearity → physical locality tradeoffs
dle multimedia Manipulation unstructured full-text documents, semi-structured (XML), large objects (
data, graphs,
Information Management
Balance implicit and explicit descriptions
Integrate semantic web with databases
Description Cooperative work using social networks
Reason about trust, privacy and security.
Information lost → conceptual, logical, physical perspectives.
Transformation
Model diversity: network/hierarchical, relational, OO, logical, semantical, graph, etc
Handle uncertain and incomplete data, normalize non-tabular data, preserve prove
Interfacing
Acquisition scattered, many providers, lack of search engines for scientific datasets (exceptions bioinforma
Data Discovery
Extraction Feasibility, preserve provenance, lack of semantics
Transference Availability, voluminous data, bandwidth, protocol
Publication Lack of intention, enforce access control, traceability

Proposals

SciFrame

Semantic-aware schemas (Ontologies ↔ Dbs)

Workflow inspection (DBs ↔ Application)

DB adaptiveness → CRUDI patterns

DB Descriptors → storage approaches
(1st candidate: locality properties)
