The Quality of a Data Product may be understood as the degree to which data satisfy the requirements defined by the product-owner organization. Uso 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.
The data have attributes that correctly represent the true value of the desired attribute for a concept or event in a specified context. Provide data management policies to ensure quality levels.
Identify responsibilities for data management and use. Semantic accuracy is defined as the closeness oso the data values to a set of values defined in a domain considered semantically correct.
The degree to which data has attributes that correctly represent the true value of the intended attribute of a concept or event in a specific context of use. The quality of the information is a key factor, because the success of the decisions made by organizations depends heavily on the quality data on which those decisions are based.
The Data Quality model represents the grounds where the system for assessing the quality of data products is built on. 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. In a Data Quality model, the main Data Quality characteristics that must be taken into account when assessing the properties of the intended data product are established.

However, the organizations often lack the means to be able to assess the quality of their data. Specifically, those requirements are the ones that are reflected in the Data Quality model through its characteristics Accuracy, Completeness, Consistency, Credibility, Currentness, Accessibility Syntactic accuracy is defined as the closeness of the data values to a set of values defined in a domain considered syntactically correct. The data have attributes with currently valid values for its specific context of use.
The degree to which data has attributes that are free from contradiction and are coherent with other data in a specific context of use.
