    In the competitive transportation sector, there’s a great need for managers to analyze the data of business processes without interrupting the daily work of an On-Line Transaction Processing (OLTP) system. The new technologies and concepts have given the opportunity to the companies for analyzing faster and more detailed results with using the Decision Support System (DSS). Improvements in the data warehousing technologies expanded the view of the business about the decision making. With the On-Line Analysis Processing (OLAP) concepts of the data warehouse, presentation of the data through multidimensional views and graphical displays provide great support for the decision-makers. With new DSS technologies, transportation companies will get chance to analyze their business more efficiently. In this thesis, we analyzed the structure of OLTP of a transportation company and we proposed the most suitable DSS model as a data warehouse based model. For the DSS data warehouse database, we modeled a hybrid structure which is suitable for the business functions’ data of the transportation company.
