XML Schema Collection

XML File

Shredding the data

Backup and Recovery

• Implementation of Log Shipping between headquarters server and secondary server located off site

• Off site location for archive server to hold legacy data and static information and also acts as the monitor for the Log Shipping solution

• Implementation of RAID 5 on production servers• High aggregation transfer rates• Backup strategies implemented both locally and at

corporate levels

Backup and Recovery (cont.)

Security Considerations

• Implement Principle of Least Privilege• Role based security• User management via groups and integrated

windows security• Stored Procedures for all interactions with data• Exclusion of all dynamic SQL statements• Use of Certificates and Symmetric Encryption• Additional security considerations will be included in

the front end applications that interface with the data
