DLI databases can be organized in 2 ways.

1. Hirerarchical sequential

access methods for this oeganization are

A) HSAM
B) HISAM
C) SHSAM
D)SHISAM

2. Hierarchical Direct

access methods for this oeganization are

A) HDAM
B) HIDAM ( Both direct and sequential access possible)

Also these access methods are for internal use of DLI and these over and above operating system access methods like SAM,QSAM,ISAM and VSAM.

They are not mutually exclusive.

Thanks,
