Commonly known as a file in unix dfsmsrfp linux. A data set is a collection of logically related data records stored on one disk storage volume or a set of volumes. A data set can be: You can print a data set or display it on a terminal. Programs and system utilities can store and retrieve records either directly or sequentially.

Programs and system utilities use disk volumes for storing data and executable programs, including the operating system itself, and for temporary working storage. Program and system utilitoes can use one disk volume for many different data sets, and reallocate or reuse space on the volume. Disk storage management is done either explicitly or through automated processes or through a combination or both. DASD volumes are used for storing data and executable programs. A disk drive contains cylinders Cylinders contain tracks Tracks contain data records.
A Data Set is assigned disk space in chunks called extents A primary extent is allocated when data set is created. FB block record record block record record record record Fixed blocked records. No defined internal structure for access method.
Record and block descriptors words are each 4 bytes long 9. Simple and efficient way to organize related groups of sequential files. Similar to a PDS, but advantages include: Space reclaimed automatically utiltiies a member is deleted Faster directory searches VSAM cluster name is associated with 1 or more physical dfsmedfp set names. itilities
The control intervals are grouped into contiguous areas of storage called control areas CA. The dfsmsdgp are the different types of VSAM data sets: ZIBM 2 qualifiers A catalog is a data set used to store location information about other data sets.
Lists the data sets on a volume Lists the free space on the volume.

A catalog is a VSAM data set with information about other data sets. Catalog records associate a data set name with disk or tape volume. Locating a data set requires: An alias entry is defined in the master catalog to direct the master catalog to look into a specifically related user catalog for the all data sets names beginning with that alias aka HLQ as the first node of the data set name.
