This curriculum spans the technical and operational rigor of a multi-workshop data engineering program, covering the breadth of responsibilities handled in enterprise data platform teams, from secure ingestion and schema governance to privacy-preserving transformation and production pipeline observability.

Module 1: Data Ingestion Architecture in OKAPI

  • Select between batch and streaming ingestion based on source system SLAs and downstream latency requirements
  • Configure secure credential rotation for accessing enterprise data sources via OAuth, Kerberos, or managed service identities
  • Implement schema versioning at ingestion to handle backward-incompatible changes from upstream systems
  • Design fault-tolerant data pipelines with retry logic and dead-letter queues for malformed records
  • Integrate metadata harvesting at the point of ingestion to populate data lineage registries
  • Apply data retention policies during ingestion to comply with GDPR and internal data governance rules
  • Validate payload size and frequency thresholds to prevent pipeline overloads from high-volume sources

Module 2: Schema Harmonization and Standardization

  • Define canonical field names and data types across disparate source systems using a centralized data dictionary
  • Resolve conflicting business definitions (e.g., "revenue" vs. "net sales") through cross-functional stakeholder alignment
  • Implement schema evolution strategies to support backward and forward compatibility in data contracts
  • Map legacy codes (e.g., product categories) to standardized taxonomies using reference data services
  • Automate schema drift detection using statistical profiling and alerting on structural anomalies
  • Enforce schema conformance using declarative validation rules before data progresses to transformation
  • Handle optional vs. required fields based on business criticality and downstream model dependencies

Module 3: Data Quality Assessment and Monitoring

  • Establish data quality KPIs (completeness, accuracy, consistency) per data domain and stakeholder SLAs
  • Deploy automated anomaly detection on statistical profiles (e.g., null rates, value distributions)
  • Configure alerting thresholds for data quality violations with escalation paths to data stewards
  • Implement reconciliation checks between source and target row counts and aggregate totals
  • Log data quality rule outcomes for auditability and root cause analysis in production incidents
  • Balance false positive alerts against detection sensitivity to maintain operational trust
  • Integrate data quality dashboards into existing observability platforms (e.g., Datadog, Splunk)

Module 4: Entity Resolution and Record Linkage

  • Select deterministic vs. probabilistic matching strategies based on data availability and precision requirements
  • Design blocking rules to reduce pairwise comparison complexity in large-scale customer datasets
  • Calibrate match thresholds to balance false merges and missed links in golden record creation
  • Manage identity resolution across organizational boundaries with privacy-preserving techniques
  • Implement survivorship rules to resolve conflicting attribute values from multiple source systems
  • Maintain audit trails of merge/split operations for compliance and rollback capability
  • Integrate with MDM systems to synchronize canonical entity identifiers across platforms

Module 5: Temporal Data Handling and Point-in-Time Correctness

  • Model slowly changing dimensions using hybrid Type 2/Type 6 approaches for analytical accuracy
  • Synchronize event time vs. ingestion time across pipelines to ensure temporal consistency
  • Implement point-in-time joins to reconstruct historical states for time-travel analytics
  • Manage timezone normalization and daylight saving transitions in timestamp fields
  • Handle late-arriving data with watermarking and reprocessing strategies in streaming contexts
  • Preserve effective date ranges in master data to support audit and regulatory reporting
  • Optimize temporal queries using clustering and partitioning on time keys in data warehouses

Module 6: Privacy-Preserving Data Transformation

  • Apply tokenization or format-preserving encryption to sensitive fields in non-production environments
  • Implement role-based data masking at the transformation layer based on user entitlements
  • Conduct data minimization by removing unnecessary PII before downstream propagation
  • Integrate with enterprise data classification tools to dynamically apply protection rules
  • Validate anonymization efficacy using re-identification risk scoring models
  • Log access and transformation of sensitive data for privacy impact assessments
  • Coordinate with legal teams to align data masking policies with jurisdictional regulations

Module 7: Scalable Feature Engineering Pipelines

  • Design reusable feature templates to standardize calculation logic across use cases
  • Optimize window function usage in SQL-based feature derivation to avoid performance bottlenecks
  • Cache and version engineered features to support reproducible model training and serving
  • Implement feature drift detection by monitoring statistical properties over time
  • Synchronize feature computation between batch and real-time pipelines using dual-write patterns
  • Register features in a central feature store with metadata on ownership, latency, and usage
  • Enforce data type consistency and missing value handling in feature generation logic

Module 8: Metadata Management and Data Lineage

  • Automatically extract technical lineage from ETL job execution logs and SQL parsers
  • Link business glossary terms to physical data assets using semantic tagging
  • Implement impact analysis capabilities to assess downstream effects of source changes
  • Synchronize metadata across tools (e.g., data catalog, BI platforms, ML systems) via APIs
  • Track data ownership and stewardship assignments within the metadata repository
  • Archive historical metadata versions to support audit and regulatory inquiries
  • Enforce metadata completeness as a gate in CI/CD pipelines for data transformations

Module 9: Operationalization and Pipeline Governance

  • Define SLA tiers for pipeline execution frequency, latency, and uptime by data criticality
  • Implement CI/CD for data pipelines with automated testing and deployment rollback capability
  • Configure centralized logging and monitoring with structured log schemas for root cause analysis
  • Enforce data pipeline access controls using role-based permissions and separation of duties
  • Conduct production readiness reviews covering scalability, resilience, and supportability
  • Manage configuration drift using version-controlled infrastructure-as-code templates
  • Schedule and document periodic pipeline health assessments and technical debt remediation
