KB10257 - Attribute storage within a shape file versus in a joined database.

Any vector attribute information that will influence the appearance of the shapes (colors, fills, line widths, etc.) upon rendering is better recorded in the shape file itself. This will result in much faster rendering each time the map view is refreshed. If, for example, roads or streets of different classes are to to be rendered using different colors or widths, it is better to enter the road/class information as a shape file attribute. Other information can be stored to the external database.
