Question 1

What is the difference between ETL and ELT?

Accepted Answer

With ETL (Extract, Transform, Load), data is transformed before loading into the target system. With ELT (Extract, Load, Transform), raw data is loaded first and then transformed in the target system — ideal for cloud data warehouses like Snowflake or BigQuery that have enough computing power for transformation.

Question 2

Do we need a data warehouse or a data lake?

Accepted Answer

A data warehouse is suited for structured data and standardized reports. A data lake also stores unstructured data (documents, images, logs) for flexible analysis and machine learning. Many organizations benefit from a lakehouse approach combining both concepts. We advise on the right architecture for your needs.

Question 3

How do you ensure data quality?

Accepted Answer

We implement automated data quality checks at multiple levels: validation rules during loading, profiling tools to detect anomalies, and monitoring dashboards for ongoing quality control. We also establish data governance processes with clear responsibilities and escalation paths.

Question 4

How long does a data migration take?

Accepted Answer

Duration depends on data volume and complexity. A straightforward migration with clear mapping is possible in 4–6 weeks. Complex migrations with data cleansing, multiple source systems, and validation take 2–4 months. We plan migrations to minimize impact on ongoing operations.

Question 5

Can you connect our existing BI tools?

Accepted Answer

Yes. We integrate all major BI tools — Tableau, Power BI, Looker, Qlik, and others — with your data platform. Whether cloud or on-premise, we create a unified data layer that feeds your existing analytics and reporting tools with consistent, up-to-date data.

Question 6

Is the data integration GDPR-compliant?

Accepted Answer

Yes. GDPR compliance is a core part of our architecture. We implement data masking, pseudonymization, access controls, and complete audit trails. Personal data is processed following the data minimization principle, and we document all processing activities for your compliance records.
