The structure of VSAM evolves around four basic concepts: the master catalog, the user catalog, the data space and, of course, the file itself which is commonly referred to as a cluster.
VSAM files can be organized by a key field in a logical sequence (key-sequenced organization), in the physical sequence in which they are entered into the file (entry-sequenced organization) or according to their relative record numbers in the file (relative-record organization).
VSAM is a large and complex subject and to study it in detail could easily require a separate book.
