Linear data set
 | This article needs additional citations for verification. (September 2017) |
A linear data set (LDS) is a type of data set organization used by IBM's VSAM computer data storage system.[1]: 5
The LDS has a control interval size of 4096 bytes to 32768 bytes[citation needed] in increments of 4096.[1]: 31 A LDS does not have embedded control information, because it does not contain control information, the LDS cannot be accessed as if it contained individual records.[2]
This data set allows for physical addressing, which allows it to be used by systems such as that Operating systems.[clarification needed] The benefit of this is that systems such as the OS can access multiple disk spindles and view it as a single storage implementation. The limitations of this, though, is that this does not make this particularly useful to higher level abstraction levels.[original research?]
