    4. Multidiensional Databases There is no universally accepted multidimenaional algebra. There are few papers with multidimensional modeling and conceptual level description. We use a terminology based on UML core metaclasses extension described in YAM (Yet Another Multidimensional Model): An Extenssion of UML writen by A.Abello et.al.. Multidimensional databases are based on Data Cube
