That is where data validation comes into the picture to ensure that your data is right, consistent, and ready to use. Whether you’re managing customer data, running analytics, or making one of the critical business decisions, validated data is the foundation of any good strategy.

But how do we make data validation efficient and foolproof? In this blog, let’s get into the importance of data validation and its benefits and discover data validation tools like Informatica, Talend, and Hevo that simplify the process. Read about the best practices as well to help you integrate robust validation into your workflows.
What is Data Validation?
- It validates the correctness, completeness, consistency, and adherence to certain criteria that the data is correct before storing, processing, or analyzing it.
- It highlights errors, inconsistencies, or anomalies to correct them to ensure the quality and dependability of the data.
- Validation can take place in any of these steps: during data entry, migration, or integration.
- Common techniques here would be checking on the type, formats, ranges, and business rules.
- Data validation verifies accuracy and cleansing errors in organizational decision-making adherence to rules, and, therefore, it is part of successful data management.
Compare data validity with data integrity to see how they determine the accuracy and reliability of data.
Benefits of Data Validation
- Data Quality and Accuracy: Data that is captured should be without errors, proper, and credible for further analysis and making decisions.
- Good Decisions: Justifies a sound platform of reliable data that will, therefore, result in the formulation of actionable insights.
- Reduces Errors and Costs: Expensive errors caused due to bad or insufficient data are reduced.
- Compliance: Helps in complying with regulation standards because of the checks of integrity and consistency of data.
- Processes: Correction of errors becomes a manual process that reduces, hence saving time and resources.
- Customer Confidence: Accuracy on data of customers means the right communication and great experiences.
