About this Product
NovaCart Retail Inc. is an online marketplace for home and lifestyle goods. Its Marketing & Personalization team wants to run targeted campaigns such as loyalty offers, win-back emails, and VIP perks, but lacks a repeatable, governed way to transform raw shopper data into a trustworthy segment table. Today, an analyst manually assembles the data in a spreadsheet, making the process slow, error-prone, and difficult to audit.
In this lab, you build a small governed data pipeline based on standard data-lake zoning: a raw zone for landed source files, a curated zone for validated and deduplicated records, and a consumption zone for marketing queries. You ingest two flat files, customers.csv and orders.csv, into the raw zone, validate and deduplicate them into the curated zone with a detailed reject log, compute per-customer metrics such as total spend and days since last order, and assign each customer to one of five segments: VIP, Regular, New, At-Risk, or Inactive. Segment thresholds are read from a YAML configuration file rather than hardcoded.
A single Python orchestrator runs ingestion, curation, and segmentation in strict order, halting on the first failing stage. A lightweight role-permission check enforces which service role can read or write each zone, while per-stage run logging provides an audit trail.
You will practice designing storage zones, validating file presence and business rules, deduplicating records by primary key, computing aggregations and joins with pandas, externalizing configuration to YAML, implementing role-based access control, and orchestrating a multi-stage pipeline with fail-fast behavior and run logging.
By the end, you will have a working, tested pipeline with sample data, run logs, and a consumption-ready shopper_segments table committed as evidence of a successful run. You will also create a short skill-mapping write-up that can be used as interview talking points and portfolio material.
