This is a fictional practice case. These are learner materials, not a completed professional service, certification, deployed app, PBIX or proprietary project file.

PREREQUISITES
Python functions and file handling plus basic SQL; complete prerequisites before the pipeline project.

CASE
A training platform exports daily enrollment files. The same file may arrive twice, a column can be missing and records can be corrected later. Design a local, repeatable ingestion pipeline.

PORTFOLIO
Local ingestion pipeline design, data-quality checks and rerun evidence

Use the four stage worksheets, case-inputs.csv, review rubric and reference reasoning. Complete the learning resources in course-sequence.csv at a pace appropriate to your starting level. The project planning allowance is not a promise about completing all course material.
