Education

Master's degree, Computer Science

Thesis title is "An Access Control Model for Data Warehouse". Thesis presents an enhanced authorization model. The proposed model attempts to fix known security deficiencies in Data Warehouse (DW) and On-Line Analytical Process (OLAP). The proposed methodology is concerned with increasing the flexibility of the format of security rules. Besides, it utilizes a combination of facts and dimensions to set the required permissions to accomplish a task. As an integral part of this model, new methodology for avoiding wrong security impacts is shown. Such impacts could occur by using Slowly Changing Dimension (SCD) techniques, which track time-variant dimension modifications. In addition, a new language is presented to implement security predicates of data warehouse access control model (DWACM). This language is proposed on the basis of a mix of two languages: Data Control Language (DCL) and Multidimensional Expression (MDX). It utilizes commands to control access on facts, dimensions or a combination of facts and dimensions, including hierarchy levels and measures. It is effective and sufficient to implement all security rules defined by DWACM predicates. Publication URL: http://paper.ijcsns.org/07_book/html/201010/201010029.html
