Gina,

More from my EE background than my (much less than yours) database
background, I think that the generators are handled as one-of-a-kind items,
not a list of types that would get used multiple times. Each
instance/installation of a "generator" is typically a $xxx,xxx,xxx.xx
multi-year construction project. If so, then "Generator #1" is just half
of the name given to a particular generator. The full name might be Plant
#5-generator #1 If that were true, IMHO a junction table would not be
appropriate.

In order to have a good database, or to explain enough to us to help, you
are going to have to start with deciding upon what the entities are that you
are going to database, and what the mission that you want it to accomplish
is. Do this without using any database terminology.


IF (and I emphasize IF, because we don't know that) you main mission were to
track and completed maintenance, then instance of required-then-completed
maintenance would be your main table. In that case the year and or date
would be merely a field, If my guess address to Gina were right, you
would probably have a table with listings of your individual generators.
The
plant # might be just half of the name of that generator, or an attribute of
that generator.

Again, these are just guesses. You'll have to tell us more to get a real
answer.

Hope that helps a little.
