Big data federated repository model

This paper introduced the concept of the term Big Data and analyzes the cause of their appearance. Big Data is a set of methods and tools for processing different types of structured and unstructured data dynamic large amounts for their analysis and use of decision support. There is an alternative to traditional database management systems and solutions class Business Intelligence. To this class belong the parallel data processing means (NoSQL, algorithms MapReduce, Hadoop). Defining characteristic for Big data is the amount (volume, in terms of volume size), speed (velocity in terms of both growth rate and the need for high-speed processing and the results), diversity (variety, in terms of the possibility of simultaneous processing of different types of structured and semi-structured data).
