lookup table

1. A special tabular data file containing additional attributes for features stored in an associated feature attribute table. The table can be an external attribute table or an INFO table that describes coverage features.
2. A special lookup table in which numeric item values are classified into categories. For example, well depth can be recorded explicitly in the feature attribute table, but displayed and used as a set of classes, such as 0 to 250 feet, 251 to 500 feet, and so on. An INFO lookup table contains at least two items: the relate item and an item named either SYMBOL or LABEL.

A collection of data used as ready reference stored in a row and column format Note: In computers, this term can refer to almost any table used to associate a name and a value.
