SQL Server Administration

Overview  Security  Server roles  Database roles  Object permissions  Application roles  Managing data  Backups  Restoration  Replication  Performance Monitoring and Optimization

Security  Server roles  Database creators  Able to create, modify, and rename databases  Security administrators  Able to create logins and modify low level statement permissions  Server administrators  Able to manage how SQL Server functions  System administrators  Able to do anything

Security  Database roles  Public  Every login is a member, permissions granted here are granted to every login  Database Owner  Has complete control over the database  Security Admin  Able to manage the logins and permissions of the database objects  DDL Admin  Used for assistant administrators; can issue all data definition language statements  Data Reader/Writer and Deny  Grants the ability to read/write or revoke read/write privileges

Security  Object permissions  Granted  Allows the action to be performed  Denied  Disallows the action even if granted in another location  Revoked  Disallows the action unless other permissions are inherited from another location  Application Roles  Grants its permissions to anyone with the correct password

Security Tips  Using views to display data  Using stored procedures to insert/update data  Dedicated login for applications

Managing Data  Backups  How often  What to back up  Restoration  Disaster recovery plan  Replication  Does it need to be done  How often  Can it be used instead of backups

Performance Monitoring and Optimization  SQL Server manages most optimization internally  There are many things that can be changed from the defaults  Query time, memory limits, parallelism  Built-in performance monitors, profiler, and counters  Can also create user-defined counters  Many optimization and monitoring tasks can be automated
