ONE WORKFLOW

Understand first. Analyze second. Drill until the problem is specific.

LightBI separates industry context from analytical capability. A hospital can contain patient, inventory, revenue and performance evidence at the same time — only supported angles become runnable.

Connect messy sources

Excel, CSV, JSON, Google Sheets, SQL databases and explicit multi-file ERP bundles.

Review what LightBI understood

Physical structure, semantic signals, grain, evidence debt and safe business perspectives.

Investigate with traceable BA

Governed metric execution, chart drill-through, subset analysis and reusable dashboards.

LIGHTBI DEEP BA

Not a KPI summary. A structured business investigation.

What happened, where, why it may have happened, what is unusual, what matters, what to verify and what remains unknown.

LightBI Deep BA Step 1 — **Step 1 — Full-source reasoning**Build the evidence map and rank the main drivers.

LightBI Deep BA Step 2 — **Step 2 — Analyze the selected subset**Click a chart group, filter the rows and reuse the same BA framework.

BUILT FOR REAL WORK

Single file, multi-file and Advanced mode.

Related ERP reports stay governed

Compare periods and roles without silently joining unrelated source rows.

Advanced when you need control

Inspect schemas, query read-only data and hand complete results back into Simple BA.

LOCAL DATA STAYS LOCAL

Your business files are not telemetry.

The portal records a random anonymous visitor ID, campaign tags and download clicks. Desktop pairing sends only a random installation ID, app version, platform and license tier. LightBI never sends IP-derived identity, imported files, column names, query results or BA findings.
