The diploma thesis on the topic "Determining the estimation of the laboriousness of the implementation of the Business Intelligence task" deals with the formulation of a method for estimating the complexity, resp. dimensional data model design effort in the phase of pre project preparation, ie at a time when no business or user requirements have been formulated and it is not possible to design the final dimensional model. The first part of the thesis outlines the issues of dimensional modeling and functional points and proposes its own method for evaluating the complexity and desigh effort of the proposed data model. In the second part of the thesis the applied problem is solved using the proposed method. The applicability of the proposed m...
