What are the traits of a successful database administrator? How do we describe a successful DBA?

A DBA who

• who keeps everything secret
• who exaggerates his trouble-shooting
• who considers the users and developers inferior and disregard the management
• who likes mystery and non-transparency.
• who likes to brag about hidden parameters and esoteric rule of thumbs
• who doesn't share knowledge and experience
• who takes credit of success and in case of failure throws blame upon network or developers
• who refuses to learn new concepts and techniques and likes status quo

Or a DBA who

• who works as bridge between network, developers, users and the management
• who facilitates the end users
• who believes in documentation, auditing, transparency
• who is really passionate about his data and the ones who manipulate it
• who enables the developers to exploit the full potential of database
• who shares knowledge, take part in community and help others
• who admits blunders and doesn't hesitate to ask for help from others
• who is daring, visionary, and change-oriented
