Providing qualitative data is one of the main objectives in organiza-tions for improvements of the quality of services provided. Assessing and im-proving the quality of data is a very difficult task due to the very large volume of data as well as, after the rapid growth of IoT devices, the different data sources and different data structure that we have today. Through this paper we are eval-uating the dimensions, metrics and existing frameworks including the respective assessment and improvement processes, thus constructing the Framework for assessment and improvement of Data Quality approach by the organization. Due to the many existing frameworks, the main focus of this paper is on frameworks that have wide implementation in various fields and not only in specific fields.
