Data analyses of telephone requests for servicing software products at Call center have been implemented. Call center business processes have been described. Conceptual model of database is presented, as well as aggregated data created with data warehouse. Multi-Dimensional On-Line Analytical Processing (MOLAP) cubes based on star and snowflake schema are implemented.
