Integration of heterogeneous databases

Abstract

Database integration implies the integration and aggregation of data from different databases within or outside the organization and use that integrated data in many real time applications. Today, due to cloud computing come into the picture there is a need of sharing the resources and need to achieve consistency also. But there are some problems like we have different platforms, different query languages, different data models, different dependencies exist among databases and applications. So, integration solves all above problems and provides a transparent environment to the user.
