Data Warehouse Testing Services

We check every step of your ETL process to catch missing or wrong data before it causes problems. Our data warehouse testing team finds duplicate records, checks for missing links, and makes sure your data is moved and changed the right way.

For large or complex data warehouses, we use smart tools like:
• QuerySurge
• Informatica Data Validation
• iCEDQ
• ETL Validator and more

We make sure your reports and dashboards are showing the right data. Our team checks:
• That all BI tools work well with your data
• OLAP tasks like slicing and drilling work as expected.
• Reports show data clearly and load on time.

As your data grows, your system needs to keep up. We test how your data warehouse handles heavy use, fast growth, and many users at once. This helps us find and fix any slowdowns or weak spots.

Your data is private and must stay safe. We test for:
• Proper access control.
• Correct use of encryption and decryption.
• Reliable backup systems.

Our qualified testing team helps make sure your data stays safe and meets your company’s security rules.

• We check everything from top to bottom — including your ETL process, performance, security setup, and how well your reports and dashboards work.
• It’s a full review to make sure everything runs smoothly.

• If you only want help with one part, we focus on that.
• For example, we can test just your ETL process or review specific items like OLAP functions or access control.
• You choose what we test.

• Dealing with large volumes of data from multiple sources? Our data warehouse testing team selects optimized data samples to ensure test quality without impacting performance.
• We also run load and stress tests to confirm your system handles high data volume smoothly.

• Data often changes over time, especially across months and fiscal periods.
• We simulate long-term data patterns (2+ years) and frequently update test sets to reflect real-world date shifts.
• This ensures your time-dependent logic functions accurately in all scenarios.

• OLAP testing involves countless combinations of filters, dimensions, and calculations.
• To avoid gaps, our testers create a traceability matrix to track coverage across all elements.
• This ensures nothing gets missed and your analytics stay reliable.

• Some components like reports or OLAP cubes need deep business understanding.
• At Cloudester, our testers bring domain experience across retail, finance, healthcare, manufacturing, and more.
• This ensures the data warehouse truly fits your operational needs.
