The primary keys are a description of an item and the version number?
That description thing worries me a bit. It leaves editing of the description as an on-going challenge, and could become messy for grouping.
I have no idea how many items you are keeping track of, but my own preferences are:
Key 1: location/department/bldg/floor/etc.
Key 2: type/name/category
Key 3: Unique ID
Key 4: Versioning
(As many or as few keys as needed to allow managing the database.)

Hi,
Looking for design ideas or experience with the following.
We are creating a DB to hold equipment where each record holds a
description of equipment. They want to have the ability to have 1 to many
"versions" of the record. For example, if a device firmware or
configuration is updated, they want to maintain the old record.
I'm thinking I can accomplish all this by simply adding a "Version" column
to the database. Version could have values such as "1.0", "1.2", or
*CURRENT if it's the latest. When a new version is needed, we simply copy
the record and update the VERSION field.
Feedback with this approach?
Thanks in advance, Paul
