In
some instances, accessing instead of owning and maintaining your own
copy of a file might be preferable. Alternatively, you might need
to read data from a locally mounted tape that was created elsewhere,
or you might need to read, write, or update data that is remotely
mounted on your network.
Note: Do not confuse the term access
with the product
SAS/ACCESS. In the context of moving or accessing SAS files across operating
environments, access means to reach and process SAS files.
SAS/ACCESS enables users to use third-party
DBMS files.
You can use these methods
to access remote SAS files:
-
CEDA (Cross-Environment Data Access)
enables you to process SAS 8 and later SAS files.
-
Using
SAS/SHARE on your client enables you to access a remote SAS
file that resides on an operating environment that a
SAS/SHARE server runs under.
SAS/SHARE facilitates a transparent concurrent
access to remote data among multiple users. Restrictions apply to
cross-release access of SAS data.
In addition,
SAS/SHARE enables you to access
certain third-party DBMS files by means of engines that are supported
by
SAS/ACCESS.
-
Without the aid of
SAS/SHARE or CEDA, you can rely upon network
services for access to remote files (both SAS files and third-party
DBMS files). Usually, the client and the server must share a compatible
architecture, and they must run the same release of SAS software.
The operating environment, the network software, and the security
software might control users' permissions to access specific remote
files. For more information, see the SAS companion documentation that
is appropriate to your operating environment, and see the third-party
documentation for the network software and security software that
you use.
