I need to put a few bossiness constants, such as a labor rate multiplier

i have come up with so far is to store them in a table, which would have
only 1 row, and a column for each needed constant.
Anyone have a better way to do this?
Failing a better way is there some way I can limit this table to only
allow one row to exist?
Stan,
I've resolved similar issues with changing regulatory agency staff. For your
application(s) I suggest a table like this:
create table labor_rate_mult (
rate real primary_key,
start_date date not null,
end_date date
)
This provides both a history of labor rate multipliers and the ability to
select either the most current one or a previous one.
If other factors affect the rate, add attribute columns for them.
