Caching in Multidimensional Databases
István Szépkúti
One utilisation of multidimensional databases is the field of On-line Analytical Processing (OLAP). The applications in this area are designed to make the analysis of shared multid…
Difference Sequence Compression of Multidimensional Databases
István Szépkúti
The multidimensional databases often use compression techniques in order to decrease the size of the database. This paper introduces a new method called difference sequence compres…
On the Scalability of Multidimensional Databases
István Szépkúti
It is commonly accepted in the practice of on-line analytical processing of databases that the multidimensional database organization is less scalable than the relational one. It i…
Difference-Huffman Coding of Multidimensional Databases
István Szépkúti
A new compression method called difference-Huffman coding (DHC) is introduced in this paper. It is verified empirically that DHC results in a smaller multidimensional physical repr…
Multidimensional or Relational? / How to Organize an On-line Analytical Processing Database
István Szépkúti
In the past few years, the number of OLAP applications increased quickly. These applications use two significantly different DB structures: multidimensional (MD) and table-based. O…
