Data quality checks and deduplication routines

Purpose

1.1. Ensure accuracy, consistency, and reliability of tax records from diverse government, municipal, and financial sources.
1.2. Systematically detect duplicates, correct data anomalies, validate data against reference registries (e.g. Anagrafe Tributaria, taxpayer database), and enforce normalizations for fiscal compliance.
1.3. Automate remediation tasks like merging, flagging, or overwriting records following rule-based or ML-driven data quality logic.
1.4. Support downstream analytics, reporting, and cross-agency collaboration with high-integrity, deduplicated master records.

Trigger Conditions

2.1. New data ingestion from local tax offices, banks, or other state bodies.
2.2. Scheduled nightly/weekly ETL batch jobs.
2.3. API payloads/streams containing taxpayer updates.
2.4. Administrator or data steward manual invocation.
2.5. System detection of predefined quality thresholds breached.
