• ODI 11g – Faster Files

  - by David Allan

  Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this?

• What do you use to bundle / encrypt data?

  - by David McGraw

  More and more games are going the data driven route which means that there needs to be a layer of security around easy manipulation.
