The problem of selecting an optimal fragmentation schema of a data warehouse is more challenging compared to that in relational and object databases. This challenge is due to the several choices of partitioning star or snowflake schemas. Data partitioning is beneficial if and only if the fact table is fragmented based on the partitioning schemas of dimension tables. This may increase the number of fragments of the fact tables dramatically and makes their maintenance very costly. Therefore, the right selection of fragmenting schemas is important for better performance of OLAP queries. In this paper, we present a genetic algorithm for schema partitioning selection problem. The proposed algorithm gives better solutions since the search space is constrained by the schema partitioning. We conduct several experimental studies using the APB-1 release II benchmark for validating the proposed algorithm.
