Research on alternate media technologies, like film, synthetic DNA, and glass, for long-term data archival has received a lot of attention recently due to the media obsolescence issues faced by contemporary storage media like tape, Hard Disk Drives (HDD), and Solid State Disks (SSD). While researchers have developed novel layout and encoding techniques for archiving databases on these new media types, one key question remains unaddressed: How do we ensure that the decoders developed today will be available and executable by a user who is restoring an archived database several decades later in the future, on a computing platform that potentially does not even exist today? In this paper, we make the case for Universal Layout Emulation (ULE), a new approach for future-proof, long-term database archival that advocates archiving decoders together with the data to ensure successful recovery. In order to do so, ULE brings together concepts from Data Management and Digital Preservation communities by using emulation for archiving decoders. In order to show that ULE can be implemented in practice, we present the design and evaluation of Micr'Olonys, an end-to-end long-term database archival system that can be used to archive databases using visual analog media like film, microform, and archival paper.

长期数据库归档的通用布局仿真

由于当代存储介质（如磁带、硬盘驱动器 (HDD) 和固态磁盘 (SSD)。虽然研究人员已经开发出用于在这些新媒体类型上存档数据库的新颖布局和编码技术，但一个关键问题仍未解决：我们如何确保今天开发的解码器可供几十年后恢复存档数据库的用户使用和执行在未来，在今天甚至不存在的计算平台上？在本文中，我们以通用布局仿真 (ULE) 为例，这是一种面向未来的新方法，长期数据库归档，提倡将解码器与数据一起归档以确保成功恢复。为此，ULE 通过使用模拟存档解码器将数据管理和数字保存社区的概念结合在一起。为了证明 ULE 可以在实践中实施，我们介绍了 Micr'Olonys 的设计和评估，这是一个端到端的长期数据库存档系统，可用于使用电影、缩微等视觉模拟媒体对数据库进行存档。 ，和档案纸。
