ITA Capstone 2016 The Gaian Database: a Dynamic Distributed Federated Database (DDFD) CUNY, IBM UK ______________________________________________________________________________ A new type of networked database architecture, the DDFD implements a Store Locally Query Anywhere paradigm, which provides for global access to data from any vertex in the database network. Why is a DDFD different? Fault tolerant and optimised, query routing: Features: Key issues addressed: Small footprint (~5Mb), minimal admin cost, open source Scalability of large distributed databases Network establishment using autonomic discovery of neighbouring nodes; query/data distribution governed by the dynamic establishment of connections Database federation Scale-free network topology Federation of heterogeneous data sources Data semantics Semantics added to distributed tables using annotations on logical tables Example applications N5 N7 N4 N6 N8 N3 N9 SQL Queries Query N10 N2 N0 N1 N11 Sensor Networks: Distributed Semantic Search: • Supports distributed queries for current and historical data • Distributed triple store and text index • Distributed registry for the ITA Information Fabric • Virtual Knowledgebase International Technology Alliance in Network and Information Sciences
