Abstract: Virtual databases are provisioned using point-in-time copies of a source database. Transaction logs received from the source database are applied to a point-in-time copy of the source database to create recovery milestones comprising database blocks that can be used to provision virtual databases. The recovery milestones are created in advance of receiving a request to provision a virtual database. Each recovery milestone is validated to determine that a consistent database snapshot can be created using the recovery milestone. If a problem is identified that prevents creation of a consistent database snapshot, the problem is fixed before creating the next recovery milestone. In response to receiving a request to provision a virtual database corresponding to a point in time, a recovery milestone is identified and transaction logs applied to the recovery milestone to create a database snapshot corresponding to the requested point in time.

Abstract translation: 使用源数据库的时间点副本来提供虚拟数据库。 从源数据库接收的事务日志应用于源数据库的时间点副本，以创建包含可用于配置虚拟数据库的数据库块的恢复里程碑。 恢复里程碑是在接收到提供虚拟数据库的请求之前创建的。 验证每个恢复里程碑以确定可以使用恢复里程碑创建一致的数据库快照。 如果确定了阻止创建一致的数据库快照的问题，则在创建下一个恢复里程碑之前，问题已解决。 响应于接收到对与时间点相对应的虚拟数据库的请求，识别恢复里程碑，并将事务日志应用于恢复里程碑以创建与所请求的时间点对应的数据库快照。

Abstract: A database storage system provides replication capability that allows data from a source database and application specific data from a source application to be replicated respectively to a target database storage system and a target application, thereby creating a virtual database and a virtual application. The database storage system generates a plurality of snapshots of the virtual database at a corresponding plurality of time points and a plurality of snapshots of the virtual application at the corresponding plurality of time points. The database storage system associates the plurality of snapshots of the virtual database with the plurality of snapshots of the virtual application at the corresponding plurality of time points so as to generate a historical time-sequence of concurrent modifications to both the virtual database and the virtual application at the one or more development environments, thereby allowing concurrent read/write and rollback, of data and applications.

Abstract translation: 数据库存储系统提供允许来自源数据库的数据和源应用程序的应用程序特定数据分别复制到目标数据库存储系统和目标应用程序的复制功能，从而创建虚拟数据库和虚拟应用程序。 数据库存储系统在对应的多个时间点的相应多个时间点和虚拟应用的多个快照生成虚拟数据库的多个快照。 数据库存储系统将虚拟数据库的多个快照与对应的多个时间点的虚拟应用的多个快照相关联，以便生成对虚拟数据库和虚拟应用程序的并发修改的历史时间序列 在一个或多个开发环境中，从而允许数据和应用的并发读/写和回滚。
