题目：Sustainable Extensibility in Big Data
摘要：In this talk, I will present a big-data system that is in production at a major international bank to manage reference data for a variety of uses, including Anti-money laundering and "know your customer"(AML/KYC), risk assessment, and regulatory compliance. The system addresses two common big-data challenges for enterprise data systems, especially in large financial institutions. The first is "sustainable extensibility" - the system can be extended to include new data sources on an ongoing basis, allowing it to extend its coverage as more stakeholders join in (a common occurrence in today's world of corporate conglomerates). The second is bitemporality - every piece of data in the system is indexed based on system time (when the fact was known) and business time (when the fact was true). A key success factor is the use of a central ontology that manages all stages of the production system, including data ingestion, data quality, security, optimization and presentation. The system has been in production use for over a year, proving the viability of the approach.
