Abstract:
The need to process and analyze large data volumes, as well as to convey the information contained therein to decision makers naturally led to the development of OLAP systems. Similarly to SGBDs, OLAP systems must ensure optimum access to the storage environment. Thus, OLAP uses indexing algorithms for relational data and n-dimensional summarized data stored in cubes. This paper presents a new n-dimensional cube indexing algorithm which provides better performance in comparison to the already implemented Tree-like index types.
