    • Techniques for transferring objects between database systems. As implemented in a relational database management system, the techniques employ a data transfer mechanism that operates under control of a master table in the RDBMS that is performing the transfer operation. The master table specifies the kind of transfer operation to be performed, a set of objects to be transferred, operations to be performed on the objects as they are being transferred, and filters for selecting a subset of the objects. During execution of the transfer, the transfer mechanism maintains and updates state in the master table such that queries may be made on the master table to determine the current status of the operation and such that the transfer mechanism may restart the operation after it has been stopped either at the request of a client that is performing the operation or because of an error in the transfer. The master table's persistence and the status information it contains permit the client that is performing the operation to detach from the operation without stopping the operation and later again attach to the operation to determine the operation's status or to perform operations such as creating new files for the operation or changing the degree of parallelism with which the transfer operation is being performed. Another feature of the transfer mechanism is using an object's metadata to determine the most efficient way of transferring the object.
    • 在数据库系统之间传输对象的技术。 如在关系数据库管理系统中实现的,该技术采用数据传输机制,其在正在执行传送操作的RDBMS中的主表的控制下操作。 主表指定要执行的传送操作的种类,要传送的一组对象,要传送对象时要执行的操作,以及用于选择对象子集的过滤器。 在执行传送过程中,传送机制维护和更新主表中的状态,以便可以在主表上进行查询以确定操作的当前状态,并且传送机制可以在停止之后重新启动操作 无论是在正在执行操作的客户端请求或由于传输中的错误。 主表的持久性和其所包含的状态信息允许正在执行操作的客户端从操作中分离而不停止操作,然后再次附加到操作以确定操作的状态或执行操作,例如创建新文件 操作或改变正在执行传送操作的并行度。 传输机制的另一个特征是使用对象的元数据来确定传输对象的最有效方式。

    • A tamper resistant container that can be readily opened by an elderly person but is difficult for a young child to open comprising a container for holding toxic substances with the container having a latch lip for engaging a cover and a pressure region located at the top of the container and over the latch lip, and a cover for engaging the container to close and seal toxic substances in the container with the container including a slip ring to permit free rotation of the container when the cover on the container is rotated to thereby thwart a young child from opening the tamper resistant container with the cover including a cylindrical lip to latch the cover to the container with the cylindrical lip operable for disengagement of the cover with the container by the user squeezing on a specific region on the outside of the container so that the container flexes inward to disengage the cylindrical lip from the container to thereby permit the user to remove the cover from the container.
    • 一种防篡改的容器,其可以容易地被老年人打开,但是对于幼儿来说难以打开,包括用于容纳有毒物质的容器,该容器具有用于接合盖的闩锁唇和位于顶部的压力区域 容器和闩锁唇上方,以及盖,用于接合容器以封闭和密封容器中的有毒物质,容器包括滑环,当容器上的盖旋转时允许容器自由旋转,从而阻止年轻人 孩子打开防篡改容器时,盖子包括一个圆柱形的唇部,以将盖子锁定到容器上,其中圆柱形唇缘可操作用于使盖子与容器分离,使用者在容器外侧的特定区域上挤压,使得 容器向内弯曲以将圆筒形唇缘与容器脱开,从而允许使用者从容器中取出盖子。
