The document provides details of SQL projects and stored procedures developed by Chris McGlothen including: 1. Projects for a bank, library, and online movie rental company including ER diagrams and stored procedures for transactions, reports, and security. 2. Stored procedures use try/catch blocks and handle errors, dynamic SQL, and pass back data to callers. 3. Projects include backup and recovery plans with log shipping and security roles, stored procedures instead of dynamic SQL, and principle of least privilege.

28. Shredding the data

29. 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

31. 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
