Data Warhouses of Hybrid Type: Features of Construction

TLDR
The conceptual, logical and physical models of distributed storages and inter-level transitions procedures are proposed, and location of data on the nodes, data replication routes are determined by criterion of the minimum total cost of data storage and processing using a modified genetic algorithm.
Abstract
Actual scientific and practical task of creating information technology for construction of distributed data warehouses of hybrid type taking into account the properties of data and statistics of queries to the storage is considered in the article. The analysis of the problem of data warehouses construction taking into account data properties and executable queries is carried out. The conceptual, logical and physical models of distributed storages and inter-level transitions procedures are proposed. Location of data on the nodes, data replication routes are determined by criterion of the minimum total cost of data storage and processing using a modified genetic algorithm.
