Sequential dataviews used in Ideal can be created in Datadictionary ( via the FILE model) or in Ideal itself. 

The sequential dataviews created in Datadictionary ( = the old way of doing this) are called Modelled Sequential Dataviews . These dataviews have ACCESS-METHOD set to QSAM .  For documentation ,see  Creating the DATAVIEW Structure for a FILE Structure.

Sequential Dataviews created in Ideal  ( =  the new way , using CRE DVW ) are called Unmodelled Sequential Dataviews  .These dataviews have ACCESS-METHOD set to SAM .  For documentation, see Defining Unmodeled Sequential File Dataviews

Datacom/DB dataviews have blanks in ACCESS-METHOD.

ACCESS-METHOD can also be VSAM for dataviews created in Ideal on VSAM files.
