您要查找的是不是：
- How does this relate to the relative record number concept? 以上所述与相对记录编号的概念有何关系呢?
- Note that the relative record number, a logical concept, and the relative sector number, it is possible to compute a relative sector number. 注意，相对记录编号（即一个逻辑概念）与相对扇区编号（即一个物理位置）是完全相同的。
- Given a relative record number, it is possible to compute a physical disk address. 就可计算出磁盘上的一个物理地址。
- An option is passing a numeric key to an algorithm and computing a relative record number. 还有一种选择就是把数值关键字传送给一个算法，然后算出一个相对记录编号。
- The relative record number is used to retrieve the logical record from the data set. 使用相对记录号可以从数据集中检索出相应的逻辑记录。
- The basic idea of direct access is assigning each record an easy-to- remember, logical key, and then converting that key to a relative record number. 直接存取的基本思想是分配给每个记录一个容易记忆的关键字，然后把那个关键字转换成一个相对记录编号，
- While we won't discuss the details, in either case it is still possible to develop a simple algorithm to compute a record's physical location, given its relative record number. 虽然我们不考虑这些细节，但以上两种情况给定了它的相对记录编号，开发一种计算记录物理位置的算法仍然是可能的。
- VSAM arranges records by an index key, relative record number, or relative byte addressing. VSAM通过一个索引键值,相关记录号或者相关字节地址来组织记录。
- Additionally, as each record is written, the customer name and the associated relative record number are recorded inan array or index (Fig. 8.8). 除此之外，当每个记录被写入时，顾客的姓名和与姓名有关的相对记录编号记录在一个数组或索引中（图8.;8）。
- Thus, we can compute the physical location of any record by adding its relative record number to the start-of-file address (which, remember, was extracted from the disk's index when the file was opened). 因此，可以用相对记录号加上文件起始地址的方法算出任意一个记录的物理位置。（记住：文件的起始地址是当文件被打开时，从磁盘的索引中得到了）。
- A number that indicates the location of a logical record, expressed as a difference with respect to a base address. The relative record number is used to retrieve the logical record from the data set. 一种指明逻辑记录位置的号码，用相对于基地址的差值来表示。使用相对记录号可以从数据集中检索出相应的逻辑记录。
- The key to many storage and retrieval techniques is the relative record number 许多存储和检索技术的关键是相对记录号。
- An option is passing a numeric key to an algorithm and computing a relative record number 还有一种选择就是把数值关键字传送给一个算法，然后算出一个相对记录编号。
- Record number of database: no limitation. 数据库记录个数：无限制。
- Reading file record number failed. 无法读取文件记录号。
- relative record number 相对记录号
- There was a record number of candidates for the post. 这个职位的候选人数量空前。
- A record number of people have been thrown out of their homes. 创纪录的人们被赶出了家门。
- Check the calculations used in generating the record number. 检查生成记录号时所使用的计算。
- The log file does not contain the requested record number. 日志文件中没有请求的记录号。
