This sounds like you would need to keep all journals online for as far back as you might ever want to look at historical data. It sounds like a very useful function for us as Higher Education always has government reporting requirements that are based on a specific date. And data changes all the time so trying to reproduce a report that was based on data from a year or two ago on a specific date is very problematic.  I guess disk is cheap so we could get a few more terabytes to keep the journals online.

Subject: Re: Temporal database feature on IBM i?

Hi Matt

I really like the idea of temporal functionality - it'd be very cool for price change history.

The word from IBM about new development in database is as follows -

The DB2 for i technical leaders (Mark & Scott) regularly review and revise the DB2 for i product strategy and enhancement plan.
They just announced DB2 for i enhancements that are being delivered on the same cadence as TR2 (7.2) and TR10 (7.1).
Customers are encouraged to follow
www.developerworks.com/ibmi/techupdatesto stay current with IBM i enhancements.

I know that doesn't directly answer your question - still, the idea is to stay tuned on that site - and I believe you can post your thoughts there - maybe!!
