What does the use of PROC FEDSQL imply about data processing?

• A. All processing is done in SAS
• B. Data must be stored locally
• C. Data processing occurs in the database
• D. Data must be owned by SAS

Answer: (C)

The use of PROC FEDSQL indicates that data processing occurs in the database. PROC FEDSQL is a procedure provided by SAS that allows users to execute SQL queries against data that resides within a variety of database systems. This means that when you utilize PROC FEDSQL, the SQL queries you write are sent to the database server, where the data is processed directly. This method is particularly advantageous because it leverages the power and efficiency of the database system to perform operations, potentially leading to improved performance and reduced data transfer since only the result sets are returned to SAS. By processing data in the database, users can work with larger datasets without needing to load all data into SAS, optimizing both memory use and processing time. Overall, PROC FEDSQL emphasizes an approach where operations are executed where the data physically resides, which enhances the capabilities to handle large volumes of data efficiently.
