The benefits of metadata-bound
libraries are as follows:
-
Metadata-bound libraries can provide
seamless, secure access to SAS data.
-
Metadata-bound libraries offer
more robust protection than do other metadata-based approaches to
access control. Because enforcement for a metadata-bound library originates
from the physical data, that enforcement occurs regardless of whether
an access request from SAS is mediated by metadata (for example, from
SAS Web Report Studio) or direct (for example, from a LIBNAME statement
that is submitted in SAS Enterprise Guide).
-
The protection that metadata-bound
libraries provide is persistent. Protections for a metadata-bound
table apply to any other instances of a physical table with the same
name in the same physical library. In other words, permissions that
you set in the metadata survive activities that affect the underlying
physical table. For example, the protections remain in place after
you recreate or replace the underlying physical table.
