Technology

A standardized schema enabling consistent representation of healthcare data across disparate EHR, claims, and pharmacy systems to support federated analytics and research. CDMs such as OMOP, PCORnet, and i2b2 are used in data warehouse implementations to harmonize terminology, patient identifiers, and clinical events for cross-system reporting.

A device or software component used in healthcare settings to automatically record environmental or physiological data such as temperature for medication storage or patient vital signs over time. Data logger output is integrated into EHR, pharmacy cold chain management, and clinical trial data systems for compliance and audit purposes.

A set of policies, tools, and technologies implemented in healthcare data environments to detect and prevent unauthorized transmission or exposure of protected health information across EHR, claims, and PBM systems. DLP solutions enforce HIPAA and organizational data governance requirements by monitoring data flows at endpoints, networks, and cloud platforms.

A legally binding contract governing the permitted uses and disclosures of a limited dataset shared between covered entities or research institutions, satisfying HIPAA Privacy Rule requirements under 45 CFR 164.514(e). In healthcare data engineering, DUAs define field-level restrictions, permissible analytics, and security controls applied to de-identified or limited datasets used in research or operational reporting workflows.

A reference or lookup table in a healthcare data warehouse star or snowflake schema that stores descriptive attributes such as provider, member, diagnosis, or facility details. Used by data engineers to join against fact tables in EHR, claims, and enrollment data models to enable slicing and filtering in downstream reporting and analytics tools.

Standardized computer-to-computer exchange of healthcare business documents between trading partners. Used in claims processing (837), remittance (835), and eligibility (270/271) transactions across payers, providers, and clearinghouses per HIPAA-mandated ANSI X12 transaction sets.

A structured, hierarchical data format widely used in healthcare data systems for exchanging clinical, administrative, and financial information. XML underlies HL7 CDA documents, X12 EDI transaction wrappers, and EHR interoperability payloads, requiring schema validation and parsing logic in ETL pipelines processing claims, eligibility, and enrollment data.

An HL7 standard defining RESTful APIs and structured data formats for exchanging healthcare information across EHR, payer, and health information exchange systems. Data engineers implement FHIR R4 resources such as Patient, Claim, and MedicationRequest to enable real-time interoperability, CMS compliance, and patient data access initiatives.

An international standards organization and messaging framework used for exchanging clinical and administrative healthcare data between EHR, lab, pharmacy, and billing systems. HL7 v2.x is widely used for ADT and lab result transactions; HL7 FHIR is the modern RESTful API standard for interoperability.

A framework of policies, technologies, and processes used to control user authentication, authorization, and access to healthcare data systems including EHR platforms, data warehouses, and payer portals. IAM systems enforce role-based access controls, audit logging, and compliance with HIPAA security rules, and are critical components of healthcare data governance and breach prevention strategies.

A discipline and set of processes used in healthcare IT to ensure a single, authoritative source of truth for core entities such as members, providers, facilities, and plans across EHR, claims, PBM, and enrollment systems. MDM eliminates duplicate records and reconciles data conflicts across disparate platforms.

The NCPDP Telecommunication Standard Version D.0 is the electronic transaction format mandated for retail pharmacy claims adjudication between pharmacies and PBM or payer systems. It defines field-level specifications for claim submission, eligibility inquiry, and claim reversal transactions processed in real time.

A continuous stretch of codons in a DNA or RNA sequence that begins with a start codon and ends with a stop codon, representing a potential protein-coding region. In genomic data systems supporting oncology or precision medicine pipelines, ORF annotations are stored in variant databases and bioinformatics platforms to identify therapeutic targets and interpret somatic mutation data.

An integrated, subject-oriented database designed for near-real-time operational reporting, sitting architecturally between transactional source systems such as EHR and claims platforms and the enterprise data warehouse. The ODS consolidates current-state member, clinical, and claims data to support daily operational workflows and analytics without impacting source system performance.

Medical imaging technology used in EHR and radiology information systems to store, retrieve, manage, and transmit digital diagnostic images such as X-rays, MRIs, and CT scans. PACS integrates with HL7 and DICOM standards, enabling data engineers to pipeline imaging metadata into clinical analytics, claims, and care coordination platforms.

A pharmaceutical manufacturing framework used in pharmacy and drug supply chain data systems to monitor and control production quality in real time. PAT data is integrated into PBM and drug formulary pipelines to ensure dispensed products meet regulatory compliance and batch integrity standards tracked by NDC.

A standardized regulatory document detailing chemical hazard, handling, and safety information required under OSHA and GHS standards. In healthcare data systems, SDS records are managed in occupational health and facility management platforms; data engineers integrate SDS data with incident reporting and employee health EHR modules.

A recombinant antibody construct consisting of fused heavy and light chain variable regions used in targeted biologic therapies. In healthcare data systems, scFv identifiers appear in specialty pharmacy, PBM formulary, and clinical trial datasets; data engineers must map these to NDC and biologic product reference tables accurately.

A data warehousing pattern that manages how reference data, such as member demographics, provider attributes, or plan details, changes over time in healthcare data systems. Data engineers implement SCD Type 1, 2, or 3 logic in EHR, enrollment, and claims EDW tables to preserve historical accuracy for longitudinal reporting.

A relational data modeling pattern organizing healthcare data into a central fact table, such as claims or encounters, surrounded by dimension tables for members, providers, dates, and diagnoses. Widely used in healthcare EDW and analytics platforms; data engineers use star schema to optimize query performance for EHR and claims reporting.
