Database preservation
open-in-new
<p>Database preservation usually involves converting the information stored in a <a href="/facts/Database/VYcpkevb">database</a> to a form likely to be accessible in the long term as <a href="/facts/Computer_technology/Kghtm9fX">technology</a> changes, without losing the initial characteristics (context, content, structure, appearance and behaviour) of the data. </p><p>With the prevalence of databases, different methods have been developed to aid in the preservation of databases and their contents. These methods vary depending on database characteristics and preservation needs. </p><p>There are three basic methods of database preservation: migration, XML, and emulation. There are also certain tools, software, and projects which have been created to aid in the preservation of databases including SIARD, the Digital Preservation Toolkit, CHRONOS, and RODA. </p>
