Most of the times SDK is referred as PDI. I assume it could be Product Development Interface but never found the exact term anywhere. Is there any accurate term for it ?
Hello there Prateek,
As Zoran said above, PDI stands for Partner Development Infrastructure. This link shows us that "You may hear of the term PDI (partner development infrastructure), which was the original name of the SDK as it was first used for partners to build reusable add-ons for C4C. As we made SDK available for customers and partners to create customer specific C4C extensions, we changed the name from PDI to Cloud Applications Studio, or SDK for short."
A curiosity is that SDK stands for Software Development Kit, (in a wider concept) so our Cloud Application Studio is a SDK.
