SAS programming is the process of writing programs using the SAS language to access, explore, prepare, and analyze data. SAS stands for Statistical Analysis Software, and it is a command-driven statistical software suite widely used for statistical data analysis and visualization. SAS is a software suite that has been developed by SAS Institute, one of the leaders in analytics, and it is useful for performing advanced analytics, multivariate analyses, and generating informative reports. SAS programming enables users to perform advanced analysis, business intelligence, predictive analysis, and data management to operate effectively in competitive and changing business conditions.

SAS programming applications are characterized by the flow control specified in the diagram below:

2. Explore data: In this phase, the data is explored to identify patterns and relationships.

3. Analyze data: In this phase, statistical analyses are performed on the data.
