The archival database of the HELP Hospital Information System at LDS Hospital is too large to be stored on line. The archival data are important for clinical and research applications. Demountable disk packs have been used to store the archival database. This method of storage has four significant disadvantages. A virtual database was developed to overcome the limitations of this data-management scheme. This virtual database enables the transparent use of appropriate low-cost network-based storage technology to provide on-line availability of the entire archive of clinical data. The virtual database successfully resolves the problems associated with disk packs, and opens the door to enhanced use of the data for clinical and research applications.
LDS医院的HELP医院信息系统的存档数据库太大，无法在线存储。存档数据对于临床和研究应用很重要。已使用可移动磁盘组来存储存档数据库。这种存储方法有四个重大缺点。开发了一个虚拟数据库来克服这种数据管理方案的局限性。这个虚拟数据库能够透明地使用适当的基于网络的低成本存储技术，以提供临床数据整个存档的在线可用性。虚拟数据库成功解决了与磁盘组相关的问题，并为加强临床和研究应用中数据的使用打开了大门。
