Showing the Benefits of Applying a Model Driven Architecture for Developing Secure OLAP Applications
Data Warehouses (DW) manage enterprise information that is queried for decision making purposes by using On-Line Analytical Processing (OLAP) tools. The establishment of security constraints in all development stages and operations of the DW is highly important since otherwise, unauthorized users may discover vital business information. The final users of OLAP tools access and analyze the infor...
متن کاملAutomatic Generation of Secure Multidimensional Code for Data Warehouses by using QVT Transformations: an MDA Approach
Data Warehouses manage vital information for the decision making process, which may be discovered by unauthorized users if we do not establish security measures in all the stages of the development process. We have proposed an MDA architecture to develop secure Data Warehouses which allows them to be modeled at different abstraction levels (business, conceptual, logical and code level). We take...
متن کاملAn architecture for automatically developing secure OLAP applications from models
Decision makers query enterprise information stored in Data Warehouses (DW) by using tools (such as On-Line Analytical Processing (OLAP) tools) which use specific views or cubes from the corporate DW or Data Marts, based on the multidimensional modelling. Since the information managed is critical, security constraints have to be correctly established in order to avoid unauthorized accesses. In ...
متن کاملDevelopment of Secure XML Data Warehouses with QVT
Context: Data warehouses are systems which integrate heterogeneous sources to support the decision making process. Data from the Web is becoming increasingly more important as sources for these systems, which has motivated the extensive use of XML to facilitate data and metadata interchange among heterogeneous data sources from the Web and the data warehouse. However, the business information t...

Decision makers query enterprise information stored in DataWarehouses (DW) by using tools (such as On-Line Analytical Processing (OLAP) tools) which employ specific views or cubes from the corporate DW or Data Marts, based on multidimensional modelling. Since the information managed is critical, security constraints have to be correctly established in order to avoid unauthorized access. In prev...
