یک کاربرد عملی از روش اختلال افسردگی اساسی ما برای مدل سازی امن XML پایگاههای اطلاعات

In order to deal with this situation, in this paper we propose a methodological approach for the model driven development of secure XML data warehouses. We also specify a set of transformation rules that are able to automatically generate not only the corresponding XML structure of the data warehouse from secure conceptual data warehouse models, but also the security rules specified within the data warehouse XML structure, thus allowing both aspects to be implemented simultaneously. We additionally introduce our secure XML DW development approach, in which the secure conceptual DW data model, the PIM, is transformed into a secure XML DW, as a PSM, by applying a set of transformation rules. Our proposal is validated through the practical application of our model driven development approach for Modeling Secure XML Data Warehouses to a case study, which is based on a central Airport DW. We first describe the transformation rules defined, then use a step by step illustration to show how they will be applied to the secure conceptual model of the case study to obtain the Secure XML Data Warehouse, thus demonstrating the benefits of our proposal, and finally we analyze how to achieve the secure implementation into commercial database management systems, providing details of the secure implementation in Oracle XML DB 11 g.
