The Method of Forming Contents for a NoSQL Storage of Configurable Information System

Configurable information systems operate under conditions of uncertainty regarding stored data and sources for filling this data. The change and expansion of functionality raises the problem of data collection and preparation, which, in turn, is connected with the integration of heterogeneous structures both in structure and in format. The technical solution to the problem is the use of ETL-systems that automate the operations of extracting, transforming and loading data into the store by rigidly defined rules. In the issues of data selection, exclusively the data specialist makes definition of rules for drive and transformation, the decision, which is a consequence of the lack of a methodological basis. This, in turn, raises such problems as the excess accuracy and inconsistency of imported data, a narrow specialization of rules (up to uniqueness) with a limited number of analytical models and known requirements for the data mart. The article presents the concept of the method for creating the content of NoSQL-storage of a configurable information system.
