• Helps recovering deleted data back into the database when a table or its components are deleted accidently.
• Ensure complete database recovery including components such as tables, triggers, indexes, stored procedures, etc.
• Offers to save resultant output either in SQL Server database or as SQL Server compatible scripts.
