To Create a Data Cache

  1. From the menus choose:

    File > Cache Data...

  2. Click OK or Cache Now.

OK creates a data cache the next time the program reads the data (for example, the next time you run a statistical procedure), which is usually what you want because it doesn't require an extra data pass. Cache Now creates a data cache immediately, which shouldn't be necessary under most circumstances. Cache Now is useful primarily for two reasons:

  • A data source is "locked" and can't be updated by anyone until you end your session, open a different data source, or cache the data.
  • For large data sources, scrolling through the contents of the Data View tab in the Data Editor will be much faster if you cache the data.
