Design and implementation of a distributed cache store of financial data replicated across 3 regions: US, UK and Hong Kong. The system handles bi-temporal queries, and derivation rules. It is implemented in Java using GemFire, the Oracle database and ActiveMQ. Design and development of a prototype using a distributed cache (Oracle Coherence and Hazelcast) and the distributed database MongoDB to evaluate the use of those technologies for a datastore of derivative products. Implemented a UI interface using Jide to fetch derivative products and display charts, grids, derivation rules.
