The article presents a new methodology for data warehousing processes, which integrates different approaches, techniques and methodologies, such as: specification of information requirements, relational modeling, combined development model based on the Kimball and Hefesto proposals, an increased process of extraction-transformation and load that explicitly incorporates a validation phase of indicators, and finally integrated and interactive visualizations for the multidimensional analysis of the obtained indicators. The proposed methodology is not only based on the theoretical aspects described in the article, but also on the experience gained by the research team in the development of various data warehousing projects, mainly oriented to the generation of indicators of academic productivity and management of a university, which corresponds to the case study application of the methodology described. The results of success in different projects where this methodology has been used guarantee its effectiveness.
