Automation & data quality management
for Data Warehouse & Data Lakehouse

We automate data management in heterogeneous landscapes – from the connected source to the consumable data application. Our tiered data quality management creates traceable, auditable processes and reliable key figures for better decisions.

Why automation & data quality are crucial now

Companies today are faced with the task, many heterogeneous data sources quickly, consistently and compliantly into one analytical data platform. We rely on  metadata-driven templates and frameworks that provide reusable building blocks and realize automation – for classic data warehouse layer models as well as for Data Lakehouse Architectures.

With modern orchestration (e.g. Apache Airflow), model-driven transformation(dbt), Python, Spark clusters and established ETL tools in on-premises environments, we automate processes end-to-end – mostly platform-independent and scalable.

At a glance

Decades of experience in consolidation in international groups ensure our customers benefit from the technical and technological expertise of our team. We have the relevant experience in group accounting to make your project a success:

  • Automated connection of dozens of data sources

  • Reusable, metadata-driven templates

  • Orchestration & code generation for DWH & Lakehouse

  • Level-based data quality management (incl. SCD)

  • Auditable according to BCBS 239 & SOX

Architecture & Orchestration

Automated data management from the source to the BI level – repeatable, testable, documented.

Automation in the data warehouse & lakehouse

Data Warehouse

  • Layer model (landing, staging, core, marts)

  • Template-based loading and transformation jobs

  • Change data (CDC) & SCD automation

  • Rule-based data lineage & versioning

 
Data Lakehouse

  • Automatic orchestration & code generation

  • Delta /Iceberg tables, ACID & Time Travel

  • dbt based models & tests as standard

  • Scalable execution on Spark clusters

Data quality management – graded & auditable

Our data quality approach is layered and systematically covers the typical quality views: master data checks, format and plausibility checks, data cleansing, syntactic and semantic checks as well as SCD automation. We visualize the results in a separate DQ data model and provide key figures for monitoring and control.

Regulations & tests

Standardized dbt tests, user-defined Python checks and SQL checks per level. Rules are versioned, documented in a traceable manner and can be rolled out in a CI/CD-controlled manner.

DQ-KPIs & Scorecards

Visualization in the DQ data model: completeness, consistency, timeliness, validity, unambiguity, etc. – including trend and cause analyses.

Compliance & Audit

Auditable traceability in accordance with BCBS 239 and Sarbanes-Oxley (SOX): lineage, control reports, dual control principle, technical and functional approvals.

Methodology & Templates

We accelerate projects with metadata-driven templates for loading, transformation and test routes. This allows us to automatically generate code, orchestration plans and documentation – sustainably maintainable and expandable.

Typical deliverables

  • Source adapters & CDC pipelines (Airflow, Python, ETL Suite)

  • dbt models incl. tests, seeds & snapshots

  • Spark jobs for large amounts of data

  • DQ regulations, scorecards & operational reports

  • CI/CD setups incl. automatic documentation

 

Technology stack (excerpt)

  • Apache Airflow, dbt, Python, Spark

  • Delta Lake / Apache Iceberg

  • Cloud DWH & Lakehouse: Azure, AWS, GCP

  • ETL/ELT: classic on premises tools

  • BI tools for reporting & self-service

ML-supported data quality monitoring

Based on the DQ history, we establish machine-learning-supported processes (e.g. anomaly detection) that signal deviations at an early stage and make data quality maturity levels measurable.
