In 2009 RBS set out to build a single store of trade and risk data that all applications in the bank could access simultaniously. This talk discusses a number of novel techniques that were developed as part of this work. Based on Oracle Coherence the ODC departs from the trend set by most caching solutions by holding its data in a normalised form making it both memory efficient and easy to change. However it does this in a novel way that supports most arbitrary queries without the usual problems associated with distributed joins. We'll be discussing these patterns as well as others that allow linear scalability, fault tolerance and millisecond latencies.
