I saw the IBM definition too. But given the usage in the original example:

I'd say the intent was to ensure a certain set of data could be "preserved" across two or more sessions, e.g.:

1. open a session,
2. populate the session with some "persistent" data from a database,
3. fill in some additional data, make changes to existing
data, or just reuse existing "persistent data" as part
of a new record,
4. store the entered/changed data in the database,
5. close the session,
6. open a new session,
7. retrieve the "persistent data" from the database,
8. and so on and so forth.

In fact, if my interpretation is correct, a collection of "persistent data" could be made up of subsets of "persistent data" that could be used in different ways and varying combinations. I can see data that's constantly reused across multiple sessions (more than two) as persistent data that usually does not change (e.g., data common to multiple records); as well as data being entered during a specific session (e.g., a name and address) being stored as a new record for reuse, in-turn becoming persistent data. After all, isn't that how a database is used? Or am I off the mark?

Though I can kinda imagine the "persistent" (npi) folks I used to work with nodding their heads in agreement, I'd still prefer the use of "preserve," unless I was writing specifically to an audience made up of "persistent" people.

They can be kinda funny about stuff like this.

I say we write around it as long as we can--and hope it is a passing fad ;)

You know, something like "store it as persistent data" or "store it in
persistent form/configuration" etc.

When it passes into the language (like "automation", "online", and so
on) or, importantly, the specific accepted usage of the domain one is
operating in, we can get with the program.
