一些领域的应用程序,如隐私、安全和完整性验证,需要直接访问数据库管理系统(DBMS)存储。然而,关系型DBMS是为物理数据独立性而设计的,因此限制了内部存储的暴露。因此,应用程序无法启用或使用临时解决方案访问存储,例如查询ROWID(可以暴露DBMS存储中的物理记录位置,但不能暴露OS存储中的物理记录位置)或使用直接读取和写入DBMS数据页的DBMS“页面修复”工具。这种ad-hoc方法的能力有限,并且难以编程、维护和跨各种DBMS移植。在本演示中,我们展示了DF-Toolkit -一组提供对DBMS存储层的抽象访问的工具。用户将能够查看无法通过其他应用程序访问的DBMS存储。示例包括未分配的(例如,删除的)数据、索引值-指针对和RAM中的缓存DBMS页面。用户还将能够与几个特殊用途的安全应用程序进行交互,这些应用程序对DBMS存储进行审计,超出了DBMS供应商的支持。
Applications in several areas, such as privacy, security, and integrity validation, require direct access to database management system (DBMS) storage. However, relational DBMSes are designed for physical data independence, and thus limit internal storage exposure. Consequently, applications either cannot be enabled or access storage with ad-hoc solutions, such as querying the ROWID (which can expose physical record location within DBMS storage but not within OS storage) or using DBMS "page repair" tools that read and write DBMS data pages directly. Such ad-hoc methods are limited in their capabilities and difficult to program, maintain, and port across various DBMSes. In this demonstration, we showcase DF-Toolkit - a set of tools that provide an abstracted access to the DBMS storage layer. Users will be able to view DBMS storage not accessible through other applications. Examples include unallocated (e.g., deleted) data, index value-pointer pairs, and cached DBMS pages in RAM. Users will also be able to interact with several special-purpose security applications that audit DBMS storage beyond what DBMS vendors support.
