• While being a DBA is exciting and lucrative,
  it's a career choice that requires years of
  preparation.  The most important thing to
  remember is that the job of a DBA requires a
  24x7 commitment.  Being an Oracle DBA can be a
  very stressful, thankless job, and many DBA jobs
  require the DBA to be on-call on Thanks giving to
  perform downtime maintenance.

• This illustrates that like most industry
  buzzwords, Big is a cynical spin on what should
  more often be called awkward. A billion rows of
  normalized data in a well-designed schema might
  be large, but it's hard to see a big pay packet
  coming from running an aggregate function like
  Average on it. To be a lucrative skill there has
  to be some pain that you can overcome for your
  patient employer.

• YOU know how the Fat Controller (yes, its
  called that at one bank) sucks in data and no one
  else does, not well enough that theyd ever dare
  lose you. Thats good until the day that some
  jerk whispers Hadoop into the ear of your CIO.
  Then what you have are non-portable skills that
  can only be used in one firm which is phasing
  them out. This is so bad that you must be that
  jerk. It's better to be leading the charge than
  be ridden over and even if the project goes tits
  up, Hadoop is a pretty good word to have on your
  CV.

• Apparently Im not the most valuable writer
  at The Reg, our wise leadership has crossed sales
  of adverts with click data to work that out.
  However, Im too petty to tell you who is because
  that is actionable data, since a rational
  response is a positive feedback loop pushing the
  parts of your business that make money and fixing
  or junking parts that dont.
• Talking to Duncan Ross, who evangelises Big Data
  for Tera data, I discover that the first skill
  you need to develop is the mindset of working out
  what would be good to know so that you can use
  it. Being interesting is necessary but not
  sufficient.

ORACLE DBA

• Each database requires at least one database
  administrator (DBA) to administer it. Because
  an Oracle database system can be large and can
  have many users, often this is not a one person
  job. In such cases, there is a group of DBAs who
  share responsibility.
