© Hortonworks Inc The Application Development Dilemma Today, application developers devote roughly 80% of their code to persisting roughly 20% of the total data flowing through their applications –80% of the data flowing through our applications is at best lost in rolling log files, at worst never collected -- without ever being analyzed or accounted for –For the remaining 20% we do currently collect – application-level database programming, licensing, storage, administration, and ETL processing have maxed out IT operations budgets and have constrained app development teams from keeping pace with the rate of change in the business Page 2

Field parsing –Unique values –Unique values per field –Access to values of each field independently from the record –Relatively fast field-based searches, without indexing –Value encoding –Etc… These are cross-cutting concerns!

How do we address cross-cutting concerns without disturbing the existing process flow? Page 4

© Hortonworks Inc Fraud Prevention Business Problem Financial institutions are always at risk of fraud Fraudsters test bank systems for vulnerabilities This testing leaves subtle patterns often undetected by bank employees or law enforcement Fraud losses costs banks millions Solution HDP reduces the cost to detect fraudulent activity HDP stores more types of data for longer Analysis of data in the “data lake” exposes fraudulent patterns that would have gone undetected Financial Services Data: Server Logs

Field parsing - unstructured data is not all that unstructured… –Unique values –Unique values per field –Access to values of each field independently from the record –Relatively fast field-based searches, without indexing –Value encoding –Etc… These are cross-cutting concerns!
