Implementation of NoSQL-based Data Warehouses

Data warehouses traditionally are built using relational databases.The main reason for that -data warehouses mostly are used in enterprises with large-scale data sets stored in relational data structures of different legacy systems.Though rapidly developing non-relational databases also are still rather unusual in data processing tasks.This paper discusses the possibilities and advantages of using document-oriented NoSQL database management systems in data warehousing.The paper describes processes and implementation aspects of building data warehouses using a NoSQL data storages.The research is based on practical experience gained during implementing of NoSQL data marts in MongoDB.
