DATA MIGRATION ACROSS HETEROGENEOUS NoSQL DATABASES IN A BIG DATA CONTEXT

The recent growing interest on highly-available data-intensive applications sparked the need for flexible and portable storage technologies, e.g., NoSQL databases. NoSQL databases have emerged as the solution to handle large quantities of user-generated content still guaranteeing fault-tolerance, availability and scalability. NoSQL databases offer differentiated properties and characteristics as well as different data models, architectures and data access interfaces. As a result of these heterogeneities, the development of applications exploiting such kind of technology is strictly dependent on the specific NoSQL solution being adopted.
