  abstract      = {In the multidimensional model supported by OLAP data is represented in logical dimensions to provide a consistent view of business data over time. These dimensions, although representing static information, sometimes need to be updated or new entries need to be added. However, updates to the time dimension are different than updates to other slowly changing dimensions and therefore must be handled differently. This paper addresses the issues related to updating the time dimension showing how the common techniques for handling dimension updates can or cannot be used. It also gives examples for common structural and instance updates and presents an algorithm to perform them supported by the SQL code for its implementation. Finally, it resolves general issues related to dimension updates and addresses their effect on the time dimension. These issues seem to have wide application, and yet, more in-depth investigations need to be conducted in this field for real-world time-based analysis in enterprise-wide data warehouses.}
