WORK vs. PERMANENT Library
In SAS, there are only two types of libraries:
WORK vs. PERMANENT
The WORK Library is the temporary library. It contains all the working data sets. No data set from this library will be saved after the program is closed.
The rest of the libraries (whether it is the built-in libraries or one that you created yourself) is called the PERMANENT library.
The PERMANENT library contains permanent data sets. You will need the LIBRARY reference to access these libraries. However, the permanent library allows you to save the data sets even after the program is closed.
Let's learn more about PERMANENT library in the next session.
