Kontrola kvality dat v datovém skladu a její reporting

The diploma thesis deals with the solution of data quality within the data warehouse of a financial institution, where the main goal is the implementation of a pilot solution of the data quality control project and the proposal of its future reporting. The first chapters contain a search of the literature, followed by an analysis of concepts related to issues such as data, methods of storing them, working with data and their categorization. Subsequently, the areas of data quality management are described - the concepts of data management, data governance and business intelligence. The middle chapter is devoted to the data quality itself, its definition, connection to other industries and thus forms a theoretical core for the practical implementation of data controls. The final chapters deal with the practical implementation of the pilot solution, first the definition of the project itself and analysis ofthe current state of data quality in the researched institution supplemented by a description of components entering the current data quality monitoring solution and their possibility of further use in our project. The penultimate chapter fulfils the main goal of this work, where we find the applied solution shown on the example of two pilot data checks. At the end of the work, there is a proposal for the future development of the project in the direction of modifications of structures and the possibility of adding user-friendly tools providing dashboarding or alerting.
