AI-assisted data analysis on the company’s own data warehouse

32 documented metric tables cover revenue, margins, stock and purchasing. AI answers business questions about them in conversation, without SQL or a prepared report. The endpoint is read-only, authenticates each client and revokes deleted tokens immediately.

The warehouse answers business questions in conversation

Business users previously accessed consolidated commerce data only through prepared reports. Every other question became a request and had to wait.

Four tools now lead from business documentation through table listings and schema descriptions to read-only queries. The customer retains its own AI application.

The starting point: indirect access to answers

Questions from purchasing, controlling and product management cut across stock, sales, margins and marketplaces. No prepared report covered that combined view.

Terms such as stock cover or gross profit had different definitions across analyses.
Orders and line items were available as raw data rather than query-ready metrics.
Direct database access for AI was ruled out.
The system runs inside a VPN, without the OAuth flow used by common connectors.

The turning point: four tools with a defined access boundary

01

Consolidated metrics

Reporting tables combine revenue, gross profit, stock, stock cover and ABC classes. One question can now query them together.

02

Secured the endpoint

During implementation, we found that the database timeout did not cover certain queries. We added a second service-level deadline that forcibly closes hanging connections. SQL validation permits only individual read queries, with row and time limits.

03

Managed access

Tokens are created in the application, which stores only a hash. Every query carries the client name, and deleting a token invalidates it immediately.

04

Documented the data for AI

Curated documentation explains 32 tables, joins and query recipes so product, stock cover and gross profit have consistent meanings.

The endpoint runs in production inside the VPN. The customer’s AI application queries the reporting layer directly.
