Linear data set
 | This article needs additional citations for verification. (September 2017) |
A Linear DataSet (LDS) is a type of data set organization used by the VSAM computer data storage system.[1]
The LDS has a control interval size of 4096 bytes to 32768 bytes in increments of 4096. A LDS does not have imbedded 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. 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.
