Oracle BI EE provides a feature called double columns.
When a repository is configured for the double column feature, column data includes a display column that has a code column mapped to it (that is, it has double columns).
A display column contains the display values for the column data,
for example, Excellent, Good, and Poor. A code column contains code values that uniquely identify display values and are consistent across users or locales,
for example, the code values 1 (uniquely identifying Excellent), 2 (uniquely identifying Good), and 3 (uniquely identifying Poor).
