    • A system and method for restoring a database are described. The method may comprise requesting to begin receiving notifications of transactions that occur in the database. In response to the request, notifications of a plurality of transactions that occur in the database may be received, and information specifying the plurality of transactions may be stored. The method may further comprise receiving user input requesting to restore the database to a previous state. In response, the stored information may be retrieved, and a graphical user interface indicating the plurality of transactions specified by the stored information may be displayed. The method may further comprise receiving user input to the graphical user interface selecting a particular transaction of the plurality of transactions. In response, the database may be restored to a particular point in time relative to a time at which the particular transaction occurred.
    • 描述用于恢复数据库的系统和方法。 该方法可以包括请求开始接收在数据库中发生的事务的通知。 响应于该请求,可以接收在数据库中发生的多个事务的通知,并且可以存储指定多个事务的信息。 该方法还可以包括接收请求将数据库恢复到先前状态的用户输入。 作为响应,可以检索所存储的信息,并且可以显示指示由所存储的信息指定的多个事务的图形用户界面。 该方法还可以包括接收用户输入到图形用户界面,选择多个事务的特定交易。 作为响应,可以将数据库恢复到相对于特定事务发生的时间的特定时间点。

    • A drill pipe 10 comprises an elongate pipe section 12 having a substantially uniform pipe outer diameter 18 and a substantially uniform pipe inner diameter 20. A pin tool joint 14 is welded at one end to the pipe section, and a box tool joint 16 is welded to the other end of the pipe section. Each of the pin and box tool joints includes a thread for mating engagement and preferably first and second shoulders. The drill pipe has a ratio, R, which takes into consideration the pipe inner diameter, PID, the pipe outer diameter, POD, the tool joint inner diameter, TJID, and the tool joint outer diameter, TJOD. This ratio may be expressed as: R = ( P ID + TJ ID ) ( TJ OD - P OD ) . According to the present invention, this ratio is greater than 8.0, and is preferably from 8.1 to 8.5, thereby providing a drill pipe with desired strength and fluid flow capabilities.
    • 钻杆10包括具有基本均匀的管外径18和基本均匀的管内径20的细长管段12。 针工具接头14的一端被焊接到管部,并且盒工具接头16焊接到管部的另一端。 销和盒工具接头中的每一个包括用于配合接合的螺纹,并且优选地具有第一和第二肩部。 考虑到管内径,管径,管外径,工具接头内径TJ,钻杆的比例R, ID< / SUB>和工具接头外径TJ 。 该比率可以表示为: R = P ID MO> TJ ID MO> MI 根据本发明,该比率大于8.0,优选为8.1〜8.5,由此提供具有所需强度和流体流动能力的钻杆。
