Midrange users,

SQL 2016 will be introducing a temporal database feature which appears to be journaling on steroids.

Apparently oracle already has this feature.

Just wondering what is the feature equivalent on DB2 for the i?

Here are screenshots of the feature:

You basically add a clause to your SQL that says "FOR SYSTEM_TIME AS OF 'date/time value'" at the end of your SQL and voila, you get a picture of your table(s) as of a particular point in time. No reading cryptic squished together fields in journals, just natural queryable data!

Not only that you can "stretch" your database to the cloud, so all historical data is housed off site in presumably cheaper compute/storage infrastructure rather than your expensive on-premise database. Which makes sense for historical data since you are likely not looking at it very often.
