Data warehouse: estudo de caso em um órgão público

Abstract

The need to improve and add value to existing data analysis processes in TCE-PR, motivated the authors to search, study and research in the area of data warehouse solutions, thus aiming to add new solutions, improvements, resolution problems and data integration challenges from different systems and Parana state databases. Supported by a large number of systems, the current staging of the TCE-PR’s environment did not support the integration of data between databases from different government agencies as well as the use of techniques for performance improvement, data processing and control of problems related to incremental load, which prevented the environment for consolidating data management focused on decision making. With this motivation, this thesis provides solutions for creating a data warehouse prototype, and providing efficient methods for collecting, cleaning and analyze the data. The identification of these methods has enabled the extraction of management reports through data integration processes.
