# DuBStep Checkpoint 3

• Overview: Use a precomputation period to make queries faster.
• Grade: Scored out of 10 points

Databases designed for analytics are frequently required to respond to queries very quickly -- The longer you make an analyst wait, the harder it is to explore a dataset. Fortunately, however, analysts are often ok with a preparation period: a chance to 'load' data in. In this checkpoint, we'll be moving closer to this interactive setting. This means several things:
