I’m somebody who believes in absolutes. My old boss used to tell me that I saw the world in terms of black and white while ignoring the gray. He’s probably right. I think being anal-retentive about things makes me a better DBA.
There are a few rules that I believe in and don’t like to budge on.
- Developers don’t touch production. Ever.
- We don’t install objects in the MASTER or MSDB databases. It’s too easy to create a database opposed to polluting system databases.
- We don’t make system changes during peak use times. Changes go in during off-hours or maintenance windows.
- The fewer people who have the SA and service account passwords, the better.
- If you need a login to a database server, it’s going to be your active directory account.
- Use triggers sparingly.
- Triggers don’t send mail. Ever. Your users will have a bad experience should the Exchange server go down. Instead, use the trigger to write to a queue table and use a scheduled task to send e-mail.
- Database servers and web servers can be friends, but they shouldn’t live together.
- If I can’t justify something to an auditor, you can’t do it.
Those are some of my rules. What are the rules in your environment?
