The paper discusses the possibilities of using non-relational databases as data warehouses' (DW) data mart - an area traditionally covered by relational databases. The authors highlight potential benefits when using non-relational databases (NoSQL) technology based on the main characteristics of classical relational data base management system (RDBMS) based DW. The paper outlines a creation and production process for DW using a NoSQL data mart and develops requirements for technology necessary for such processes based on practical experience when implementing NoSQL data marts with MongoDB and Clusterpoint DB. Since there currently do not exist of-the-shelf reporting solutions for most of the NoSQL data storages the authors develop requirements for a reporting solution necessary for NoSQL based DW.
