比如，访问也许被设为：用户拥有某文件的读写权限，而组拥有该文件的只读权限，并且该文件拒绝这个系统上的其他用户访问。

由于是根据程序代码内的定义读写文件，没有外部数据定义，这使得数据共享很难且不可能进行专门报告。
Because a file was written and read according to definitions within the program code, there was no external data definition, making data sharing difficult and AD hoc reporting impossible.
所以文件系统缓存可以很大程度上帮助避免对磁盘的读写操作。
So the file system cache can help there quite a bit to avoid read and write operations on the disk.
而直接I/O 可以避免使用文件系统缓冲区，因而对于磁盘的读写更为高效。

你可以使用这些数据来找出哪些程序在经常读写硬盘，然后在这些文件安全的基础上，选择是否排除。

文件系统就算把硬盘格式化成系统可以读写操作的一种“表”结构。
A file system is a formatting of the disk into a table that the operating system can read, interpret, and write to.

因为典型的tmpfs文件系统会完全驻留在RAM中，读写几乎可以是瞬间的。
Because a typical TMPFS filesystem will reside completely in RAM, reads and writes can be almost instantaneous.
适配器可以在包含分隔符的文件中读写数据。
The adapter can both read and write files that contain a delimiter.
当解析器读写大型文件(特别是文本格式的大型文件)时，并不能达到其读取较小的文件或计算简单函数时的性能。
They don't work as well with reading large files, particularly in text format, as they do with reading much smaller files or calculating simple functions.
对应用程序透明：应用程序会将RAID作为一个整体，我的文本编辑器才不会关心它加载或者保存的文件是要读写多个磁盘的。
Transparent to the application: applications using the RAID as a single device. My text editor doesn't care that the file it is saving or loading is split across many disks.
随着程序对该文件进行读写操作，AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.
如果有可以兼容的文件系统，系统也可以读写那个分区。
If you have other drives, and they have a compatible file system, then it'll read them as well.
包括读写文本文件的便捷方法，快速地列举目录，对内存映射文件的支持。

Instead of IO, where you could read a file and write a file, ABC's designers decided to just have global variables in the program.
如果文件系统数据结构正好与底层物理分区大小一致，对4096字节数据结构的读写会产生对单一扇区的读写。
If the file system data structures happen to align perfectly with the underlying physical partition size, a read or write of a 4096-byte data structure results in a read or write of a single sector.
DATAFILES是每个外部表的必需子句，它指定读写数据的文件路径。
DATAFILES is a mandatory clause for each external table. It specifies the file path where the data can be read from or written to.
