    • An inexact query transformation system selects a query element from a query statement. If an inexact transformation improves the query performance, the system prioritizes the candidate transformation rules applicable to the selected query element. The system applies the candidate transformation rules to the selected query element to generate a transformed query element that includes a transformed remote query element. If the transformed remote query element is pushdownable, the system adds the transformed remote query element to a transformed inexact query output. Otherwise, the system applies additional candidate transformation rules to the selected query element to generate the transformed inexact query output. The system applies the transformed inexact query output to a heterogeneous datastore to provide an output query result.
    • 不精确的查询转换系统从查询语句中选择查询元素。 如果不精确的转换提高了查询性能,系统将适用于所选查询元素的候选转换规则确定优先级。 系统将候选变换规则应用于所选择的查询元素,以生成包含经变换的远程查询元素的变换查询元素。 如果转换后的远程查询元素是可下载的,则系统将转换后的远程查询元素添加到已转换的不精确查询输出。 否则,系统对所选择的查询元素应用附加的候选变换规则以生成变换的不精确查询输出。 系统将转换的不精确查询输出应用于异构数据存储区以提供输出查询结果。

    • A virtual binding system ensures that the WORM logic for protecting data immutability cannot be circumvented, effectively guaranteeing WORM property of a WORM storage system composed of rewritable magnetic hard disks. To close the security hole between the rewritable media and the WORM logic, virtual binding securely authenticates the legitimacy of a WORM logic controller before granting data access on a WORM storage media. Furthermore, the system verifies the legitimacy of the WORM logic controller during data access. This approach virtually binds together the WORM logic controller and the WORM storage media even though the WORM logic controller and the WORM storage media may be physically separate.
    • 虚拟绑定系统确保不能避免用于保护数据不变性的WORM逻辑,有效地保证由可重写磁性硬盘组成的WORM存储系统的WORM属性。 要关闭可重写介质和WORM逻辑之间的安全漏洞,虚拟绑定安全地验证WORM逻辑控制器的合法性,然后授予WORM存储介质上的数据访问权限。 此外,系统在数据访问期间验证WORM逻辑控制器的合法性。 即使WORM逻辑控制器和WORM存储介质可能是物理上分离的,这种方式实际上将WORM逻辑控制器和WORM存储介质绑定在一起。

    • A storage device backplane and an identification circuit for identifying using situations of the storage device backplane are provided. The storage device backplane possesses a first connection interface and a second connection interface, for being used as a first backplane supporting a motherboard, or a second backplane cascaded to the first backplane, or a first backplane supporting a daughterboard of the motherboard. The first and second backplanes possess the same storage device backplane structure. If the storage device backplane is used as the first backplane, a first connection interface of the first backplane is coupled to the motherboard or the daughterboard thereof; if the storage device backplane is used as the second backplane, a first connection interface of the second backplane is coupled to a second connection interface of the first backplane. The identification circuit identifies using situations of the storage device backplane and display corresponding correct indicator number.
    • 提供了存储设备背板和用于识别存储设备背板的使用情况的识别电路。 存储设备背板具有第一连接接口和第二连接接口,用于作为支撑母板的第一背板或级联到第一背板的第二背板或支撑母板的子板的第一背板。 第一和第二背板具有相同的存储设备背板结构。 如果存储设备背板用作第一背板,则第一背板的第一连接接口耦合到主板或其母板; 如果存储设备背板用作第二背板,则第二背板的第一连接接口耦合到第一背板的第二连接接口。 识别电路识别存储设备背板的使用情况,并显示相应的正确指示器编号。
