What are the 8 dimensions of data quality?

Data quality dimensions are essential factors used to assess how dependable and effective data is for its intended purpose.They help us understand if the information we collect and use is complete, accurate, and ready to support important decisions. These dimensions are essential for maintaining trust in data and preventing common problems that businesses often face.
The data quality definition is all about how well the data fits its purpose. In simple terms, good data should be correct, clear, and consistent.
Here are the eight main dimensions of data quality explained in a simple way:
Accuracy – The data should represent the real-world facts correctly. For example, a customer’s name or phone number should be true and updated.

Completeness – All necessary information should be available. Missing entries or blank fields can create confusion and slow down processes.

Consistency – Data should remain the same across all platforms and records. When one system shows a customer as active while another shows them as inactive, it leads to confusion and errors.

Timeliness – The data must be up to date and accessible when required. Relying on outdated information can result in ineffective or incorrect decisions.

Validity – Information should follow the correct format or rules. A date should look like a date, and a phone number should follow the right pattern.

Uniqueness – There should be no duplicates. Each record or entry must appear only once to avoid double counting or confusion.

Integrity – The relationship between different pieces of data should make sense. For instance, if a product is linked to a category, that category must exist in the system.

Relevance – Data should be meaningful and useful for the task or goal. Irrelevant data takes up space and adds no real value.

By concentrating on these eight essential data quality dimensions, organizations can enhance how they gather, organize, and utilize their data effectively.This helps minimize data quality issues and creates a more reliable base for making informed decisions.
Understanding and applying the right Dimensions of data quality is the first step toward making data a true business asset.
