Data Quality – ISO/IEC 25012
Data Quality Evaluation and Improvement The assessment and improvement of data quality aims to analyze the iiso 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.
However, the organizations often lack the means to be able to assess the quality of their data. The data have attributes with currently valid values for its specific context of use.
It can be either or both among data regarding one entity and across similar data for comparable entities. The Data Quality model represents the grounds where the system for assessing the quality of data products is built on.
Syntactic accuracy is defined as the closeness of the data values to a set of values defined in a domain considered syntactically correct. Provide data management policies to ensure quality levels. From this point of view data quality depends on the technological domain in which data are used; it is achieved by the capabilities of computer systems’ components such as: The degree to which subject data associated with an entity has values for all expected attributes and related entity instances in a specific context of use.
Know the value of the data to make better decisions. The Data Quality characteristics are classified in to main categories: The data have attributes that are considered certain and credible to users. The data have attributes that correctly represent the true value of the desired attribute for a concept or event in a specified context. 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.
The quality requirements of your data, i. It has two main aspects: Semantic accuracy is defined as the closeness of the data values to a set of values defined in a domain considered semantically correct. 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.
The data are free of contradictions and are consistent with the rest of the data of 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. From the inherent point of view, data quality refers to data itself, in particular to: Mitigate the data-related risks across the organization.
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. Specifically, those requirements are the ones that are reflected in the Data Quality model through its characteristics Accuracy, Completeness, Consistency, Credibility, Currentness, Accessibility Have absolute confidence that the data are reliable.
Become a strategic business ally, providing the most important asset. The quality of the information is 2501 key factor, because the success of the decisions made by organizations depends heavily on the quality data on which those decisions are based. Access to a copy of the data to be evaluated.
Therefore, AQCLab has developed a framework for evaluating and improving the data quality. Identify responsibilities for activities related to the data. The data model, which must specify at least the name of the tables, the attributes of each table, 2501 the relationship between the tables.

The Quality of a Data Product may be understood as the degree to which data satisfy the requirements defined by the product-owner organization.
Optimize resources in the execution of data-related activities. What is necessary to know the Data Quality level of your data? You can get more information by reading our Cookies Policy.
Latest news ProEducative 3. System dependent data ido refers to the degree to which data quality is reached and preserved within a computer system when data is used under specified conditions.
