Scale and Volume: The sheer size of India's population makes managing a single, comprehensive database an immense challenge. Billions of records for various services (e.g., land records, taxes, health, and social welfare) must be stored, managed, and updated in real-time.
Data Integrity: Ensuring the accuracy and consistency of data is a major hurdle. With information coming from various sources and departments, there's a high risk of duplication, errors, and outdated entries, which can lead to service delivery failures and fraud.
Security and Privacy: Protecting a centralized database from cyberattacks, data breaches, and misuse is a monumental security risk. The government must invest heavily in robust cybersecurity measures to maintain public trust.
