Healthcare Data Warehouse: Overview

Healthcare Data Warehouse for Data-Driven Health Care  - ScienceSoft

ScienceSoft has been providing a full range of data warehousing services since 2005.

Data Warehouse in healthcare: The fundamentals

A healthcare data warehouse is a centralized repository for a healthcare organization’s data retrieved from disparate sources, processed and structured for analytical querying and reporting.

Healthcare data warehouse architecture

An enterprise data warehouse in healthcare is a central element of a BI solution that includes:

A data source layer

– healthcare data from internal and external data sources (ERP, EHR/EMR, CRM, claims management system, pharmacy management systems, etc.).

A staging area

– intermediate temporary storage, where healthcare data undergoes the extract, transform and load (ETL) or the extract, load and transform (ELT) process.

Data storage layer

– includes centralized structured storage. It may also have data marts – healthcare DWH subsets oriented to a specific business line (HR, accounting, etc.) or department (radiology, intensive care, pediatrics, etc.).

Analytics and BI

– business analytics, data mining, data reporting and visualization tools.

Key features to look for in the healthcare DWH

Data integration

  • Ingesting structured, semi-structured, unstructured healthcare data (from EHR systems, ERP, HR management systems, public medical databases, claims management systems, etc.).
  • ETL/ELT-based healthcare data integration.
  • Full and incremental healthcare data extraction/load.
  • Controlled healthcare data loading/management.
  • Healthcare data transformation of varying complexity (data type conversion, summarization, etc.).
  • Healthcare data loading and querying using SQL.
  • Big data ingestion.
  • Streaming data ingestion.

Data storage

  • Integrated, historical, summarized, subject-oriented healthcare data storage.
  • Protected Health Information (PHI) storage.
  • Metadata storage.
  • Options of healthcare data storage environments (cloud, on-premises, hybrid).


  • Healthcare data indexing.
  • Materialized view support.
  • Result-caching.
  • Elastic automated scaling of storage and compute resources.
  • High performance query processing.
  • ML capabilities to dynamically manage performance and concurrency.

Security and compliance

  • Granular row and column level security control.
  • Multi-factor authentication.
  • Healthcare data encryption at rest and in transit (including backups and network connections).
  • Dynamic healthcare data masking.
  • Ongoing threat detection and vulnerability assessment.
  • Compliance with healthcare regulations (HIPAA, FDA, HITECH, etc.).

Need a DWH for Transparent Healthcare Analytics?

ScienceSoft is ready to implement your healthcare data warehouse solution to help you consolidate disintegrated data and leverage all-encompassing analytics.

Valuable integrations for a healthcare DWH

A data lake

While DWHs store highly structured healthcare data ready for analysis, data lakes serve as a cost-effective repository of semi-structured and unstructured healthcare data (clinical data, physicians’ notes, etc.). Data stored in the data lake can be further used to develop ML models (for example, predicting hospital demand).

Enabling healthcare business users to be flexible and self-reliant in analyzing, visualizing and reporting healthcare data structured in the DWH, which results in the easy transfer of analytics insights to the decision-makers and a shorter time-to-insight.

What determines medical data warehousing success

Proof of Concept

Validate your healthcare DWH solution with a PoC to better understand its real potential and get real-life user feedback.

Healthcare DWH scalability and flexibility

To instantly upload any type (structured, semi-structured, unstructured) and amount of healthcare-related data to efficiently address new data analytics objectives.

Focus on security and healthcare data protection measures

Store and process sensitive patient data within highly secure environments (AWS, Microsoft Azure, Google Cloud or private servers), ensure all-time data encryption and dynamic data masking, restrictive data access, multi-factor user authentication, healthcare DWH vulnerability assessment and penetration testing, etc.

Key financial outcomes of a healthcare DWH

As a central element of a BI solution, healthcare DWH enables consolidation of disparate healthcare data sources into a structured healthcare data repository ready for analysis to improve business and clinical decision-making and to:

  • Improve health outcomes.
  • Improve healthcare resource management.
  • Decrease healthcare operating costs.
  • Accelerate data-driven labor management.
  • Personalize care delivery and improve patients’ experience.
