Lookups
provide lists of valid values for certain items of information. This has two
key advantages:
- It ensures
that all users use the same terminology, which makes it easier to inquire
and report on the information.
- It speeds up
data entry because you can enter just enough to identify the value, and
the system completes the entry.
In Oracle HRMS, a list of values is
called a lookup type. Each value comprises a code, a meaning, and
sometimes, a legislative tag.
