This repository contains the following:

1. SQL sample code of APL APIs.
2. Sample data for the sample codes.
   • For HANA On Premise, the standard HANA import statement or the HANA studio import feature must be used to import the folder dataForHANAOnPremise.
   • For HANA Cloud, the SAP HANA database explorer import Catalog objects feature must be used to import the archive dataForHANACloud.tar.gz.
3. Reference implementations of the runtime code needed when exporting a model built by APL. Runtime code is provided for the following languages:
   • C++. Find the details and instructions here
   • java. Find the details and instructions here
   • javascript. Find the details and instructions here
