The project implements a complete data ingestion and migration framework using Pentaho Data Integration (PDI) 9.4, designed to populate and consolidate information in a new healthcare information system. It covers two major data domains:
1. Master Data Loading (Excel/CSV Sources)
2. Patient Data Migration (SQL Server/CSV Sources)
If I had to do it again, I would focus earlier on defining a strict data structure validation layer before loading anything into the target system. Setting those rules from the beginning would have saved time in later iterations when new sheets and files appeared with unexpected formats or missing fields.
