Business problem

Tariff data needed more than a simple file load. The process required controlled validation, reliable SQL loading, and a way to preserve historical changes instead of replacing the prior state each time a new file arrived.

Without a structured ingestion pattern, tariff updates could become hard to trace, hard to audit, and harder to reuse in downstream analytics. The workflow needed staging, cleanup, and history-aware publication so the data could support operations with more confidence.

System built

Built local / Azure Blob ingestion, column mapping, rate cleanup, field validation, staging-table loads, stored-procedure upserts, and current/history views for tariff master data.

The result is a pipeline that behaves like an operational data platform rather than a one-time import. It accepts source files, shapes them through controlled steps, and publishes SQL outputs designed for reuse, support, and historical review.

Review controls

Signals reviewed

The pipeline checks source readiness, schema alignment, field quality, rate normalization, upsert readiness, and publication status so tariff data can be trusted as it moves into downstream reporting and operational analysis.

Processing workflow

How it works

01

Receive

Collect tariff source files from controlled intake locations and prepare them for processing.

The workflow starts by treating the source file as an operational input instead of a one-off spreadsheet, making the load more repeatable and more reliable.

02

Map

Map incoming columns into the target schema and align source fields with expected SQL structures.

This reduces fragility when source files shift slightly and helps the pipeline keep a stable contract between file layout and database design.

03

Validate

Apply field checks, date checks, rate cleanup, and row-level validation before records move into SQL.

The validation layer protects downstream tables from malformed rows, missing values, and tariff records that are not ready for controlled publication.

04

Upsert

Load clean rows into staging tables and run stored-procedure logic to merge records into current and history structures.

The upsert pattern preserves a clean operational table while also maintaining a more useful historical trace of tariff changes over time.

05

Publish

Expose usable SQL outputs through current and history views for reporting, audits, and downstream analytics.

The final layer turns the ingestion process into a dependable data asset rather than a one-time file load.

System layers

What the pipeline coordinates

Ingestion control

Handles source-file intake, batch awareness, and load preparation so the pipeline starts from a repeatable operational entry point.

Validation layer

Checks required fields, normalizes rate and date values, and filters out rows that are not ready for SQL publication.

Staging + upsert

Uses staging tables and stored procedures to control how source data becomes current-state and history-state records.

History model

Maintains current and historical views so tariff changes can be reviewed over time instead of being overwritten and lost.

Impact signals

What the pipeline improved

Effective-dated tariff history instead of overwrite-only loading

Staging-to-current pattern for safer SQL publication

Stored-procedure upsert control

Batch traceability for review and support

Cleaner downstream reporting and analytical reuse

Operational value

Why this platform matters

More controlled ingestion

Turns tariff loading into a governed process with staging, validation, and publication layers rather than a fragile spreadsheet import.

Better historical traceability

Preserves change history so tariff updates can be reviewed across time instead of only seeing the latest version.

Safer SQL delivery

Separates raw intake, staging, and published outputs so downstream users can trust the current and history views more confidently.

Stronger business reuse

Makes tariff data easier to support in reporting, audits, pricing analysis, and future automation work.

Why this project matters

Master-data pipelines become far more valuable when they preserve both operational usability and change history.

This project shows how tariff ingestion can move beyond raw file loading. By combining source intake, schema mapping, validation, staging, and stored-procedure upserts, the pipeline creates a controlled path from spreadsheet-like source files into reliable SQL data assets.

The current-and-history design is especially important because it preserves business context over time. Instead of only seeing the latest tariff state, the platform helps support auditing, change review, and downstream analysis built on a more trustworthy historical foundation.
