In 2015, PayPal had to pay $7.7 million to the US government when their lack of proper screening mechanisms led to 500 PayPal transactions worth $44,000, violating sanctions against Iran, Cuba, and Sudan.

In 2018, Samsung Securities incurred a cost of $105 billion when an employee issued 2 billion shares to 2,018 company employees instead of dividends totaling 2 billion won (South Korean currency).

Bad data costs companies billions of dollars every year. That’s why you need a data validation tool to ensure your data is accurate, consistent, and reliable.

What are Data Validation Tools?

Data validation tools automatically check and verify data for accuracy, completeness, and conformity to predefined standards. An organization can set up certain rules or conditions like including data from up to five years for analysis. Any value that doesn’t meet the specified criteria will be excluded. These tools meticulously examine and scrutinize the data by employing various functions to flag and rectify discrepancies.

Let’s review the top 7 data validation tools to help you choose the solution that best suits your business needs.

Features to Look Out for in Data Validation Tools

  1. Custom Rules

The ability to create specific rules, expressions, and conditions based on business requirements is crucial. A data validation tool should be able to tailor, customize, and modify the criteria based on evolving needs to ensure adaptability.

  1. Data Profiling

Data profiling enables an organization to analyze the current sources of its data and understand the structure, quality, and relationships between attributes. This overview of data highlights problems within the dataset, such as inaccuracies, inconsistencies, and irregularities. Therefore, it is essential for a data validation tool to provide an assessment of the data quality in real time.

  1. Data Transformation

Data is often in raw form and needs to be transformed into a usable format. A data validation tool should have features that include cleaning the dataset to account for missing values, converting inconsistent data into a standard format, joining/merging different datasets to provide a complete view, and, finally, enriching the data by adding new variables from external sources.

  1. Data Monitoring

Another vital feature of a data validation tool is the ability to monitor and track data over time and alert in case of errors, discrepancies, or anomalies. By informing users of any changes in data events, alerting can assist in responding, rectifying, and resolving mistakes promptly to preserve the overall quality of the data.

  1. Data Testing

Data testing or data validation refers to verifying whether the data meets the predefined conditions and constraints set so that the data aligns with the business objectives. By applying various data quality checks, the data is filtered and refined for consumption. This feature ensures that the data is healthy, trustworthy, compliant, and ready to be used for analysis. Data validation tools features

Must-have features

While selecting a data validation tool, it is essential to look out for these key features:

  1. Real-time health checks: The ability to track and monitor the data in real-time enables users to identify and resolve data quality issues as they arise. This offers a complete view of the data’s health, highlighting opportunities for cleansing, transforming, standardizing, and validating the data.
  2. Interactive Data Grid: The ability to preview, analyze, and interact with data offers the flexibility to modify it as needed. Users should be able to make the necessary changes within the grid to ensure data accuracy and consistency.
  3. Automation: A data validation tool should have a built-in scheduler so that whenever a file is dropped in the mailbox, the process automatically runs the data against the predefined rules, ensuring accuracy and automating the process.

Criteria for Selecting the Right Data Validation Tool

There are several factors that influence the decision regarding the data quality tools selection process. It is important to ensure that the features and capabilities of a data validation tool are aligned with the organization’s requirements.

The following factors stand out:

  • Data Requirements: A data validation tool should be capable of dealing with diverse data structures, formats, and sources. An organization may be dealing with structured, semi-structured, and unstructured data. Hence the data validation tool should be flexible enough to accommodate the unique demands of the various data types while maintaining quality.
  • Scalability: As data volume continues to grow, an organization should choose a solution that can handle vast amounts of data efficiently. The tool should, therefore, exhibit scalability and apply data quality checks on large datasets without compromising the speed and accuracy of data processing.
  • User-friendly Interface: Setting up custom data validation rules and checks is complex for users with a non-technical background, emphasizing the need for a simple and easy-to-use tool. By offering an intuitive approach to validate the data, such as a drag-and-drop interface and point-and-click navigation, the tool results in short learning curves and few errors, streamlining the validation process.
  • Ease of Integration: Finally, data validation tools should integrate easily with existing systems and workflows. Compatibility and connectivity with various data types and sources within an organization, such as databases, cloud systems, and APIs, are crucial to integrating the data effortlessly.

Benefits of Using Data Validation Tools

Without proper data validation mechanisms, enterprises might run into issues such as skewed analysis, flawed insights, and delayed or inaccurate decision-making. A data validation tool enhances an organization’s data management efforts for several reasons:

  1. Improved Data Accuracy

Data validation solutions prevent the spread of erroneous data throughout an organization’s systems by detecting mistakes early in the data entry or import process. This allows for well-informed decisions and accurate analysis.

  1. Resource Efficiency

Manual data validation takes time and is prone to human errors. Data validation software automates the process, quickly discovering anomalies and irregularities without requiring extensive human interaction. This automation saves time, allowing teams to focus on more strategic responsibilities.

  1. Regulatory Adherence

Maintaining correct data is not only desirable but necessary for businesses governed by strict norms and standards. Data validation solutions help organizations achieve compliance obligations by guaranteeing the correctness and integrity of their data. Compliance, in turn, helps avoid penalties and instills confidence in stakeholders who rely on accurate data for audits and reporting.

Final Words

Validation is essential for ensuring the integrity and trustworthiness of data throughout its lifecycle. As new data sources emerge, it is crucial to apply business-specific data validation rules and conditions to ensure that it is in the desired format.

Carefully analyzing the factors discussed above will help you choose the right data validation that meets your data requirements. Investing in data validation tools, such as Astera, can help your business avoid costly errors, ensure operational efficiency, and gain a competitive edge.
