In the previous
figure and throughout this document, the term SAS data sources is
used to describe data sources that you have defined in the SAS ODBC
Driver. These can include SAS data sets, flat files, and VSAM files,
as well as data from many database management systems (DBMSs) through
the use of
SAS/ACCESS software.
(
For more information,
see SAS Data Sets.)
If your PC
is connected to a TCP/IP network, you can access both local data sources
and remote data sources. (For more information about software requirements,
see
What Software Do I Need?.) Local data is data that you access through a SAS server
on your local machine. The data can be stored either on your computer's
hard drive or on a network file system, such as a NetWare Windows
NT file server, or a Windows shared folder, that makes the physical
location of the data transparent to applications. Remote data is data
that you access through a
SAS/SHARE server that runs on another (remote)
machine.
The ability to use the SAS ODBC Driver
with
SAS/ACCESS software
as a gateway to DBMS data is particularly useful in the following
situations:
-
When the DBMS vendor does not offer
an ODBC driver. In this situation, you can use the SAS ODBC Driver
with
SAS/ACCESS software
on the SAS server to connect to the DBMS.
SAS/ACCESS software to the
DBMS must be licensed.
-
You do not have a software license
for the necessary software (either an ODBC driver for the DBMS or
DBMS network access software) on your client machine.
-
You want to merge DBMS data with
other data.
Currently,
SAS/ACCESS software is available
for the following systems:
-
-
-
DB2 under UNIX, Windows, and
z/OS
-
-
-
-
-

SAS/ACCESS interfaces, see
