This curriculum spans the technical and organisational complexity of a multi-workshop data warehouse implementation, addressing the same design, governance, and operational challenges encountered in large-scale advisory engagements and internal platform modernisation programs.

Module 1: Defining Strategic Alignment and Business Requirements

  • Selecting source systems for integration based on business-critical KPIs and data availability constraints.
  • Negotiating data ownership and access rights with departmental stakeholders during requirement gathering.
  • Mapping regulatory reporting needs to dimensional models for auditability and traceability.
  • Deciding between real-time vs. batch ingestion based on SLA requirements and source system capabilities.
  • Documenting lineage expectations for executive dashboards to meet compliance standards.
  • Resolving conflicting definitions of revenue across finance and sales departments during data modeling.
  • Establishing data freshness thresholds for operational reporting versus analytical use cases.
  • Identifying high-impact data domains to prioritize in the initial warehouse rollout.

Module 2: Data Modeling for Analytical Performance

  • Choosing between star schema and data vault models based on volatility and audit requirements.
  • Designing conformed dimensions to ensure consistency across multiple business processes.
  • Implementing slowly changing dimension strategies (Type 1, 2, or 3) based on historical tracking needs.
  • Denormalizing fact tables to improve query performance on large datasets.
  • Handling degenerate dimensions from transactional systems without natural dimension attributes.
  • Modeling role-playing dimensions for dates, locations, or employees used in multiple contexts.
  • Defining grain for fact tables to prevent aggregation errors in reporting.
  • Managing surrogate key generation in distributed ETL environments.

Module 3: Data Integration and ETL Architecture

  • Configuring error handling and alerting for failed ETL jobs in production pipelines.
  • Optimizing incremental load logic to minimize processing time and resource consumption.
  • Implementing retry logic and backpressure handling in streaming data ingestion.
  • Designing staging layer structures to support reprocessing and debugging.
  • Validating data completeness and accuracy after transformation using row count and checksum checks.

  • Securing credentials and connection strings in ETL configuration files.

Module 4: Data Quality and Validation Frameworks

  • Defining data quality rules for nulls, duplicates, and referential integrity in dimension tables.
  • Implementing automated data profiling during initial data onboarding.
  • Creating alert thresholds for anomaly detection in daily data volume and value ranges.
  • Handling mismatched data types during transformation from heterogeneous source systems.
  • Logging data quality violations without blocking downstream processing.
  • Reconciling discrepancies between source system totals and warehouse aggregates.
  • Establishing ownership for data issue resolution across business units.
  • Versioning data quality rules to track changes over time.

Module 5: Performance Optimization and Query Tuning

  • Designing partitioning strategies for large fact tables based on query patterns.
  • Creating and maintaining materialized views for frequently accessed aggregations.
  • Indexing dimension table keys and filtered columns to accelerate joins.
  • Configuring workload management rules to prioritize critical reporting queries.
  • Analyzing query execution plans to identify full table scans and bottlenecks.

  • Linking business glossary terms to physical database columns and reports.
  • Tracking data lineage from source systems to final dashboards for impact analysis.
  • Implementing data stewardship workflows for metadata updates and approvals.
  • Integrating with data catalog tools to support search and discovery.
