There may, in fact, not even be any connectivity with data marts in other workgroups, departments, or lines of business.
实际上,它们甚至与其他工作组、部门或业务线中的数据集市没有任何连通性。
Because the concept of "lines" isn't relevant for binary files (logical data constructs are not generally terminated by newlines), you must always specify the number of bytes that you wish to read in.
由于“行”的概念与二进制文件无关(逻辑数据结构通常都不是由新行终止),因此您必须指定需要读入的字节数。
Note that you have to read the data using sysread because you are reading raw binary packets (not lines).
请注意,您必须使用sysread来读取数据,因为您读取的是原始二进制包(而不是行)。
