The
preservation of information systems is one of the biggest challenges of
digital preservation. Among those systems we can find databases. Databases
support the majority of the information management systems, showing
themselves as a valuable resource to preserve.
If in one
hand there is a need to migrate databases to newer ones that appear with
technological evolution, on the other hand there is also the need to
preserve the information they hold for a long time period, due to legal
duties but also due to archival issues. That being said, that information
must be available no matter the database management system where the
information came from.
In this
area, the existing products for relational database preservation are still
scarce - CHRONOS and SIARD are the main ones. The first one is, in most of
the cases, unreachable due to the associated costs. The second one only
supports basic features.
Therefore
there is the urge to explore the main features and limitations of the
existing products in order to improve 'db-preservation-toolkit'
(http://keeps.github.io/db-preservation-toolkit/), an extracted component
from the RODA project (http://www.roda-community.org).
Therefore,
'db-preservation-toolkit' was inproved with
respect to performance and also adding new features in order to support
more database management systems, address some
missing features of the other products and provide an interface where it is
possible to see and search the information of the archived database.
