Development of methods for receiving analytical data from different SQL/ NoSQL databases and leading to uniform format

In this paper unified structure formation method (ETL) development for operative analysis of data stored in different SQL and NoSQL databases are considered. Unified structure formation method (ETL) is based on work with Map Reduce parallel model. In order to perform the method following steps should be considered: development of searching forms (pattern) for data searching in different database, transforming results of searching through Map Reduce parallel model, taking pre-aggreagtional data during transforming process and preparing data for downloading to data warehouse.
