Add materialized views to capture parsing errors from browser, location,
device, and geo raw staging tables and route them to dedicated error
tables in the ODS layer. Refactor DDS refresh logic to handle partial
data arrivals where device and geo events may arrive independently by
using a unified click_id source with LEFT JOINs. Add TRUNCATE command
to prevent duplicate data accumulation in DQ summary table.
Add batch ETL pipeline with ODS→DDS→DM transformation jobs and scripts.
Create DDL infrastructure with automated database schema application.
Update Makefile with transform target for executing batch processes.
Rewrite README with complete Russian documentation including architecture
diagrams, quick start guide, and data flow visualization.
