Abstract (Summary of the Work)

With the use of data warehousing and online analytical processing (OLAP) for decision support appiications, new security issues arise. Traditionally data warehouses were queried by high level users (executive managers, business analysts) only. As the range data warehouse access is steadily growing. this assumption is no longer appropriate and the neccesity of proper acess control arises. The basic aim of this work is to implement a strategy for controlling access to different aggregated views (cubes and sub-cubes) for different users based on their privileges for an OLAP application built over a relational system. To achieve this objective, a mechanism to specify privileges for different users on different category attributes and variates of a particular raw data table and a naming convention for aggregated views has been used.
