Database preservation usually involves converting the information stored in a database to a form likely to be accessible in the long term as technology changes, without losing the initial characteristics (Context, Content, Structure, Appearance and Behaviour) of the data. ==Database preservation projects== In the past different research groups have contributed to the solutions of the problems of database preservation. Research projects carried out in the past in this regard include: * Software independent archival of relational databases (SIARD)〔http://arxiv.org/abs/cs/0408054v1〕 * Repository of Authentic Digital Objects (RODA)〔http://repositorium.sdum.uminho.pt/bitstream/1822/8226/1/RodaAndCrib.pdf〕 * Digital Preservation Testbed〔http://www.digitaleduurzaamheid.nl/bibliotheek/docs/volatility-permanence-databases-en.pdf〕 * Lots of Copies Keep Stuff Safe (LOCKSS)〔http://www.lockss.org〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Database preservation」の詳細全文を読む スポンサード リンク
