The Data Quality characteristics are classified in ios main categories: From the inherent point of view, data quality refers to data itself, in particular to: Data quality is evaluated through the following characteristics: However, the organizations often lack the means to be able to assess the quality of their data.
System dependent data quality refers to the degree to which data quality is reached and preserved within a computer system when data is used under specified conditions. The assessment and improvement of data quality aims to analyze the quality characteristics of the data stored by an organization, detecting the weaknesses and proposing the improvements necessary to ensure that the data stored have the desired quality.
