ETL = Extract, Transform, Load
aka get the data you need out of the big db where it's all a mess, tidy it up and stick it nicely packaged into a small db specifically built for your purpose.

The small db is a data mart.

Be warned - enterprise ETL tools (Ab Initio, Informatica etc) cost an absolute fortune. Which you'll think of as cheap when you start looking at day rates of competent contractors (hell, even of incompetent ones).
