agent builder RAG

[Rajavelu]

Hi Experts,

I would like to understand difference between RAG and Agent Builder Data store.
I understand RAG uses vector data for retrieval and data store contains indexed documents.

1)Now which one i have to choose if I am having 80 PDF documents and which approach is more accurate if I need some information from on of the document?

2)Sometimes the table data inside pdf documents retrieval using agent app and data store is not accurate. It couldn't retrieve data of columns inside some contents of pdf document.

Kindly help me to understand.
