Life Cycle of SA

Let’s understand the Lifecycle of SAS

The new release of SAS Model manager from the leader in business analytics makes it easier and quicker to register, validate, deploy, monitor performance and retrain models

You can evaluate monitoring result, identify the problem and we can also use the models in data exploration and data preparation.

Overview of SAS

There are three phases namely Compile phase, Executive phase and output phase

When the compilation phase is complete, the descriptor portion of the SAS data set, containing the variable names and their attributes, is created. If the DATA step successfully compiles, then the execution phase begins. During the execution phase, the DATA step reads and processes the input data line by line and in the output phase we get the final output.
