Abstract

From time to time there have been different models of data integration to manage and analyze data. Also with the emergence of big data, the database community has proposed newer and better solutions to manage such disparate and large data. Also, the changes in the data storage models and massive data repositories on the web have encouraged the need for novel data integration models. In this article, we try to present a case of various trends in integrating data through different models. We present a brief overview of Federated Database Systems, Data Warehouse, Mediators and new proposed Polystore Systems with the evolution of architecture, query processing, distribution, automation and data models supported within those data integration models. The similarities and differences of these models are also presented. Also, the novelty of Polystore Systems with various examples is discussed. This article also highlights the importance of such system for integrating large scale heterogeneous data.

Keywords: Data integration, Multi-database systems, Polystore systems.
