What is Data Quality (DQ)?

Data quality is a perception or an assessment of data's fitness to serve its purpose in a given context. It is an ongoing and measurable effort.

Dimesions of data quality include:

Dimensions What is it?
Accuracy How correct is the data?  Does it represent or measure what it is intended to represent or measure?
Accessibility Is the data available for access? How easily and quickly is the data retrievable?
Reliability Is the data available can be regarded as true and credible?
Completeness Is any data missed? Is all the data sufficient in breadth & depth for the task in hand?
Appropriate Representation Is the data available presented in the same format? Is it represented compactly and is the volume of data available enough for the task in hand?
Ease of Manipulation Is the data available easy to manipulate and apply to different tasks?
Interpretability Are the data languages, units, symbols etc. are clearly defined and easily interpretable?
Relevancy / Timeliness Is the data up-to date?  How applicable and helpful is the data to task on hand?
Security Is the data restricted appropriately for confidentiality & privacy?
Understandability How easily comprehendible is the data that is available?
Value added Is the data available beneficial and provides advantages from its use?

Within an organization, acceptable data quality is crucial to operational and transactional processes and to the reliability of business analytics / business intelligence (BI) reporting.

Data quality is affected by the way data is entered, stored and managed. Data quality assurance and management is the process of verifying the reliability and effectiveness of data.

Data Quality assurance and maintenance requires “Scrubbing” of data periodically – that is,

  • Standardizing Data (Consistent representation)
  • De-duplicating Data (Eliminating duplicates)

to create a single view of data, even if it is stored in multiple systems.
