Rental Data Preparation and Enrichment
This workflow section brings together rental data from multiple sources, filters and classifies it, and then enriches it with additional information. First, the main rental dataset is split into two groups: one filtered for rows with specific distance criteria, and another classified using business rules. These two groups are then combined into a single, unified table. In parallel, mapping and lookup tables are read in, summarized, and enhanced with new columns and unique row identifiers. Additional string processing is applied to further refine the data. Lookup tables for default drivers are also filtered and enriched with calculated fields, preparing all datasets for downstream analysis or reporting.
