CSPEX is committed and dedicated to insuring that we make your data more valuable to the degree that you can measure our services based on increases in your sales. High-quality data needs to pass a set of quality criteria. Those include:

Accuracy: an aggregated value over the criteria of integrity, consistency, and density

Integrity: an aggregated value over the criteria of completeness and validity

Completeness: achieved by correcting data containing anomalies

Validity: approximated by the amount of data satisfying integrity constraints

Consistency: concerns contradictions and syntactical anomalies

Uniformity: directly related to irregularities and in compliance with the set 'unit of measure'

Density: the quotient of missing values in the data and the number of total values ought to be known.
