Abstract: Information from multiple databases is retrieved and stored on a database storage system. Multiple point-in-time copies are obtained for each database. A point-in-time copy retrieves data changed in the database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system. Each file in the set of files created for a VDB is linked to the database blocks on the database storage system associated with a point-in-time copy of the source database. The set of files associated with the VDB are mounted on a database server allowing the database server to read from and write to the set of files. Workflows based on VDBs allow various usage scenarios based on databases to be implemented efficiently, for example, testing and development, backup and recovery, and data warehouse building.

Abstract translation: 来自多个数据库的信息被检索并存储在数据库存储系统上。 为每个数据库获取多个时间点副本。 时间点副本从检索先前的时间点副本后检索数据库中已更改的数据。 通过在数据存储系统中创建一组文件来创建虚拟数据库（VDB）。 为VDB创建的文件集中的每个文件都链接到与源数据库的时间点副本相关联的数据库存储系统上的数据库块。 与VDB相关联的一组文件安装在数据库服务器上，允许数据库服务器从该文件集中读取和写入。 基于VDB的工作流程允许基于数据库的各种使用场景被有效地实现，例如测试和开发，备份和恢复以及数据仓库构建。
