Main data validation steps

Effective validation is a well-orchestrated process. At Nannostomus, we’ve refined it into key data quality validation steps.

1. Define validation rules

We start our data validation procedures with understanding your unique data needs and contexts. Based on these, we define suitable validation rules like range limits, acceptable formats, or uniqueness.

2. Apply validation checks

Nannostomus runs data validation testing and then puts info through our advanced validation system. Here, our experts incorporate a range of checks to ensure comprehensive scrutiny of your information.

3. Identify errors

During the data validation and verification process, we flag any details that don’t comply with the established rules. This makes it easy to isolate and address problematic entries.

4. Correct errors

Based on the errors’ nature, we either rectify them where possible or remove the faulty information to preserve the integrity of your data set.

5. Verify

We re-verify the details to ensure all errors have been properly addressed. Once the information passes this final validation check, it is ready for your data validation use.

6. Ongoing monitoring

Validation isn’t a one-time event. We provide continuous and real time data validation to ensure sustained information accuracy and reliability.
