Question 1

What problem does this project solve?

Accepted Answer

Enterprise knowledge is scattered across databases and document stores with no unified natural-language interface. Employees waste time finding the right system, writing SQL, and reconciling answers. This POC proves Azure-native RAG can unify access with citations and role-aware retrieval.

Question 2

How does the agent architecture work?

Accepted Answer

An Orchestrator Agent receives each user message and routes to a RAG Agent (unstructured documents via Azure AI Search) and/or a Tool Agent (NL-to-SQL against registered databases). Results merge into one GPT-4.1 response with inline source citations streamed over SSE.

Question 3

How is access control enforced?

Accepted Answer

Microsoft Entra ID groups map to data-access roles. Chunks are tagged with role metadata at ingestion; Azure AI Search filters by the user's group memberships at query time. SQL queries are scoped to permitted tables per role.

Question 4

Can admins tune behavior without redeploying?

Accepted Answer

Yes. Prompts, model selection, generation parameters (temperature, top-p, max tokens), and retrieval settings (top-k, similarity threshold, chunk size, hybrid weights) live in a versioned Cosmos DB config store with 30-second cache TTL hot-reload.

Question 5

What was validated by this POC?

Accepted Answer

That Azure OpenAI + Azure AI Search + Microsoft Agent Framework can support enterprise multi-source RAG with admin control, retrieval-layer RBAC, and Application Insights observability — documented as a blueprint for production rollout.

Question 6

Is a live demo or preview available?

Accepted Answer

No. This project was delivered for an enterprise client under confidentiality agreements. Live previews, product screenshots, and repository links are intentionally omitted from this case study due to client policies and NDAs.

Question 7

What is Enterprise AI Chatbot POC: Multi-Source RAG Chatbot on Microsoft Azure?

Accepted Answer

Question 8

What problem does Enterprise AI Chatbot POC: Multi-Source RAG Chatbot on Microsoft Azure solve?

Accepted Answer

Enterprise knowledge is fragmented across disconnected systems: multiple relational databases (MySQL, MSSQL, PostgreSQL, SQLite, Oracle, Oracle Fusion Cloud), document stores (SharePoint, Azure Blob Storage, ad-hoc uploads), and no unified natural-language interface to query across all sources.

Employees must know which system holds which information, translate questions into SQL or keyword sear…

Question 9

Why was Enterprise AI Chatbot POC: Multi-Source RAG Chatbot on Microsoft Azure built?

Accepted Answer

Business teams needed one conversational entry point over data that already lived in half a dozen systems — not another siloed search box per database or document library.

I built this POC to prove the Azure stack (OpenAI + AI Search + Agent Framework) could support production-grade RAG with admin control, Entra ID–scoped retrieval, and observable latency before committing to a full rollout.

Question 10

How does Enterprise AI Chatbot POC: Multi-Source RAG Chatbot on Microsoft Azure work at a high level?

Question 11

What was the business impact of Enterprise AI Chatbot POC: Multi-Source RAG Chatbot on Microsoft Azure?
