چکیده
Abstract: The Purpose of Multidimensional modeling is to provide the business analyst with a tool to get quick answers on totals and averages from an attribute in a dataset. Moreover, the user could switch quickly to totals on sub-group level. This white paper includes description logics, language, concept language and semantic of cube operators, description of an object-centered framework for multidimensional data models to overcome common vocabulary and common understanding of multidimensional problems.

An Object Oriented Approach to Multidimensional Database Conceptual Modeling (OOMD)
In the recent past, there has been an increasing interest in multidimensional databases (MDB) and On-line Analytical Processing (OLAP) scenarios. Several multidimensional models have been proposed in the last days. However, very few works have been focused on the area of multidimensional database conceptual modeling. Moreover, they are either conceptual extensions to the classical multidimensio...
متن کاملA Procedure of Conversion of Relational into Multidimensional Database Schema
It is universally recognized that operational information systems lean on the relational model and data warehouses on the multidimensional model. The phrase On-Line Analytical Processing OLAP means summarizing, consolidating, viewing, and synthesizing data according to multiple dimensions. The process of modeling data warehouse may start from operational system’s database. It may be helpful to ...

متن کاملPhysical Data Modeling for Multidimensional Access Methods
Despite the fact that the database community has proposed a vast number of indexing methods over the years, no standard physical data model has been established like it has been achieved on the conceptual and logical level. How to optimize a given data model by using various indexing methods is still the ‚trade secret‘ of the database administrators. Only recently, some approaches have been tri...
