Abstract: In this paper a comparative analysis was made of the most frequently quoted research multidimensional models and approaches, specifying advantages and disadvantages of each one. The application software products are also studied. The . Codd's rules are analyzed and it was evaluated its applicability in the available software products for analytical data processing. A special focus is made on the multidimensionality, being a key requirement in discussed models, used in OLAP systems.

Keywords: fact, D-structures, relational algebra, software products for on-line processing
