Resumo
Digital preservation is emerging as an area of work and research
that tries to provide answers that will ensure a continued
and long-term access to information stored digitally. IT
Platforms are constantly changing and evolving and nothing
can guarantee the continuity of access to digital artifacts in
their absence.
This paper focuses on a specic family of digital objects:
Relational Databases; they are the most frequent type of
databases used by organizations worldwide.
Database Preservation Toolkit enables the preservation of
relational databases holding the structure and content of
the the database in a preservation format in order to provide
access to the database information in a long term period.
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, solutions are still scarce. Main products for relational
database preservation include CHRONOS and SIARD.
The rst one is, in most of the cases, unreachable due to the
associated costs. The second one is not really a product but
a preservation format.
The main idea behind this work was 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 improved with respect
to performance and also with new features addiction
in order to support more database management systems, address
some missing features of the other products, support
of a new preservation format (SIARD) and provide an interface
where it is possible to access and search the information
of the archived databases.
