About the technology
Data access
A data warehouse brings data from many systems into one place for analysis. It is built for reporting, dashboards, forecasting, and audit-ready business views. Teams use it when they need stable numbers instead of live application data.
Core work
Typical work includes:
- Dimensional models and star schemas
- ETL and ELT pipelines
- Data quality checks and reconciliation
- Reporting layers for BI tools
Strong specialists understand facts, dimensions, slowly changing data, and how business rules affect metrics.
Tooling
The stack often includes SQL, dbt, orchestration tools, and cloud data warehouses such as Snowflake, BigQuery, or Amazon Redshift. Some companies still run Oracle, SQL Server, or Teradata warehouses on-premises. The right expert knows how to work across both legacy and modern setups.
When to hire
Companies bring in freelance help when a warehouse is slow, inconsistent, or hard to change. They also need support during migrations, new source integrations, or BI rebuilds. In Vienna, this often fits finance, logistics, retail, and other data-heavy teams that need clear reporting across systems.
Strong profiles
Good specialists focus on data models, not just queries. They document business logic, keep pipelines testable, and know how to handle historical data without breaking reports. They also understand security, access control, and how to support both analysts and technical teams.
Working style
Remote work is common for warehouse projects because most tasks happen in SQL, pipelines, and documentation. On-site time can help when source systems, stakeholders, or domain rules are complex. In Vienna, clear English is often enough, though local business context can make handover and workshops easier.
Frequently asked questions
What clients ask us most about Data Warehouse — answered in short.
A data warehouse collects data from different systems and turns it into a consistent base for analysis. It supports dashboards, management reporting, trend analysis, and historical views that are hard to keep stable in operational systems. Companies use it when they need one trusted place for business metrics.
No. A data warehouse is structured for analysis and business reporting, while a data lake usually stores raw or semi-structured data for broader exploration. Many teams use both: the lake for flexible storage and the warehouse for curated, reliable metrics.
Bring in Data Warehouse support when you need a new model, a migration, faster queries, cleaner pipelines, or help untangling reporting issues. Freelance specialists are also useful when the internal team is busy and a delivery deadline is close. This is common during BI changes or source-system integrations.
A strong DWH specialist should also know data modeling, ETL or ELT design, orchestration, testing, and business metric definitions. Cloud warehouse services, dbt, and BI tools are often part of the work. Good documentation and clear communication matter just as much as technical depth.
A data warehouse is the data foundation; Power BI and Tableau are reporting tools that read from it. You do not replace one with the other. If reports are slow or inconsistent, the problem is often in the warehouse model or pipeline, not in the visualization layer.
Most Data Warehouse work can be done remotely because it is built in SQL, pipelines, and documentation. On-site sessions in Vienna can help when business definitions are unclear or when teams need workshops with local stakeholders. Many projects work best with a remote build and a few in-person checkpoints.
Look for clear models, readable SQL, testing, and a strong grasp of source-to-target logic. A good enterprise data warehouse specialist explains why a metric is built a certain way and can show how they prevent breakage in downstream reports. Past work on migrations, performance tuning, or complex business logic is a strong signal.
A data warehouse is common in finance, sales, supply chain, operations, and executive reporting. It is also useful in industries that need traceable numbers and historical analysis across many systems. If a team argues about whose numbers are right, a warehouse often becomes essential.
