What must be installed for PAL to work?

For the Predictive Analytics Library (PAL) to function properly, it is essential to have the SAP HANA Application Function Library (AFL) installed. The AFL framework provides the necessary infrastructure that supports the execution of various analytical functions, including predictive analytics, which are part of PAL. PAL leverages the AFL to perform its operations, allowing it to seamlessly integrate with the HANA database and utilize its in-memory computing capabilities for efficient analysis.

The ability of PAL to execute complex predictive algorithms is heavily reliant on the underlying functionalities provided by AFL. This allows users to harness advanced analytics directly within their SAP HANA environment, taking full advantage of its speed and performance benefits.

Other options mentioned, while associated with SAP HANA, do not directly facilitate the operation of PAL. Therefore, having the AFL is crucial for integrating and running the features of the Predictive Analytics Library effectively.
