Study Notes

Data Layer

Healthcare data requirements are driven by business goals and objectives.
Data comes from sources like Electronic Medical Records (EMRs), financial, supply chain, and other operational systems.
Data in source systems are optimized for transactions, not analysis.
Data integration is necessary for enterprise-wide visibility.
An operational data store (ODS) can be used as an intermediary level of data integration.
An enterprise data warehouse (EDW) is used for cleaning, transforming, and integrating data for analysis and reporting.
Analytic sandbox is an area for lower-level data to test new business rules or run data-mining algorithms.
Data marts are subsets of data from the data warehouse, typically organized by lines of business for specific analysis.
Integration combines multiple source systems into a connected EDW, often using Extraction/Transformation/Load (ETL) processes.
Virtualization provides a single interface for accessing data points across the HCO.

Analytics Layer

This includes tools and techniques to generate information and actionable insight.
Includes the knowledge of analytics teams and the software used.
Helps identify problems, develop analytical models, perform statistical analyses, and generate insights.
Analytics requires stakeholder engagement to link strategic goals to tactical decisions.
Online analytical processing (OLAP) enables fast and efficient analysis.
