Summary


As a new DBA, one of the hardest things to figure out is the philosophy behind the position. The best DBAs in the business seem to have an underlying sense or gut feeling when something is wrong, and when to speak up and say no.

Treat others as you would like to be treated with a certain amount of respect. There should be lines drawn based on your position in the organization. Those boundaries are there for a reason—responsibilities and duties are attributed to the team player based on those boundaries. You will be working closely with the team and you will depend on them doing their job. A database is dependent on a reliable framework of underlying software and hardware, which most often is not your responsibility; this makes your job very dependent on your fellow team members' expertise.

This chapter helped to show what a DBA does all day. All rules may need to be bent or modified to suit your organization's needs. Only experience and testing will allow your team to decide how best to proceed on any single rule or suggestion in this chapter.
