Modern Data Warehouse Implementation

Burning Platform End of life: Environments were not being maintained Strategy: Strategic and analytic Initiatives are dependent on next generations tools Finance, HR, Clinical, Rev Cycle, Supply Chain, etc.Cost savings: Remote hosted EDW was expensive Acquisitions, EMR upgrades, clinical record, real-time data, use case expansionOne source of truth: Adventist has multi data platforms Patch’s 2 years behind plus stability and data model concernsNeeded to decrease costOwn our own destiny: Vendor dependent Timelines/roadmaps, policies on external data, Data model restraints7

What This Will Enable in the Future A Single Source of Truth Faster and More Stable Data Processing Will create a platform to accelerate our journey for using near real time data processing vs waiting for nightlybatch processingBetter Security New platforms are combatable with new technology required for more advanced data modeling, machinelearning and natural language processingMove from Retrospective to Concurrent Analytics We will be able to handle large volumes of data and significant concurrent users without experiencing longdelays or job failuresEnable Advanced Analytics We will be able to combine Clinical, Financial and operational data moreMeet Security requirements of full monitoring, logging and person activity trackingIncrease Data Quality New platforms are combatable with technology required for Governance needs. Documented and searchabledata will increase transparency and trust in data. Master Data Management to support knowledgemanagement catalog for measures, rules, definitions, etc.8
