key|(
This section shows you how to speed up your data retrievals
by building keys for some commonly accessed columns.
A key is a list of pointers to the data records
of a table. The key is ordered by the values of the column
for which the key is defined.
Whenever Rim is performing an ``equals'' type of search,
it will use the pointers to access data records, resulting in
a much faster retrieval.
However, updates to the table are more time consuming when
columns are keyed. When possible, you should first load
the table and then build any useful keys.
