Data integrity and accuracy are essential to every organization. Many factors affect data quality. This article will examine these factors and discuss their impact on data quality.

What is Data Quality?

Data quality can be defined as "the extent to which data are consistent with the intended use."  This definition emphasizes the importance of understanding what you want from your data. Without a clear idea of how you will use the data, it isn't easy to know whether the data meets your requirements.

Factors of Data Quality

Factors of Data Quality include:

  • Integrity (reliability, current and relevant)
  • Accuracy (correctness)
  • Bias
  • Lack of Knowledge
  • Intentional Falsification

1. Data Integrity

The first step in achieving high-quality data is ensuring its integrity. The integrity of data refers to the ability of the system to maintain consistency over time.

When designing a database, you should consider how you will manage data integrity. For example, if you plan to store customer information in a relational database, you must ensure no two customers share the same name. You could do this by assigning each customer a unique identifier.

2. Data Accuracy

A second factor affecting data quality is accuracy. Accurate data is correct and reliable. Accuracy also includes completeness. If you have incomplete data, you may not be able to make proper decisions about an issue or problem.

Accuracy refers to the truthfulness of the data. It implies that the data are true and free from error. Accurate data are useful because they provide an exact representation of reality.

3. Bias

Bias occurs when there is some sort of systematic error in the data. A bias might occur because of incorrect data entry, inaccurate assumptions, or other errors.

4. Lack of Knowledge

Another factor affecting data quality is lack of knowledge. The lack of knowledge factor refers to the fact that people may unintentionally falsify data without realizing it. These actions could lead to inaccurate data.

5. Intentional Falsification

Fraud refers to the intentional falsification of data. It is often used to describe the deliberate manipulation of data. In this case, the data are intentionally altered to produce misleading results.


Achieving & Maintaining Data Integrity

Maintaining data quality and integrity is vital for any business. Consider the following factors to ensure data quality and integrity:

  • You want to ensure that you're collecting quality data from a reliable source.
  • To ensure accuracy, check often, and be vigilant about errors.
  • Use a variety of methods to verify your work. Be cautious, especially if working with large amounts of data.
  • You should be aware of cybersecurity threats and how to prevent them.
  • You need to monitor changes to your data to ensure its reliability.
  • Maintain a backup copy of all your data.
  • Ensure that your data are stored in a secure location.
  • Use a method to identify who has access to your data.
  • Make sure that you address privacy and confidentiality issues before sharing your data.
