Database Restoration & Data Masking System

Project Overview

The Database Restoration & Data Masking System was a comprehensive enterprise solution designed to restore operational databases to development servers for global contractors while ensuring data security and compliance. This complex project involved extensive data masking requirements, permission management, and performance optimization to support development teams across different time zones, particularly in India.

Key Achievements

• Developed comprehensive restoration system for operational databases to development servers
• Implemented extensive data masking to protect sensitive information
• Created database role management for granular permission control
• Built table-driven solution with stored procedures for automated restoration
• Reduced restore time from 2+ hours to 20 minutes for 500GB data (83% improvement)
• Enabled earlier daily availability for global development teams
• Developed staging process for operational data processing and masking
• Implemented permission management with role-based access control
• Created automated workflow using SSIS and SQL Server
• Delivered enterprise-scale database restoration and security solution
